Cannabidiol-Loaded Mucoadhesive PLGA Nanosphere-Chitosan Hydrogel Patch for Oral Therapeutic Applications

Posted on by

Delivering cannabidiol (CBD) directly to tissues inside the mouth could provide a new approach to treating inflammatory oral diseases such as gingivitis and periodontitis.

In this study, researchers developed a mucoadhesive hydrogel patch containing CBD-loaded nanospheres designed to remain attached to oral tissue and gradually release CBD. The formulation demonstrated sustained CBD release, improved mucosal permeability, strong antibacterial activity and reductions in inflammatory markers.

The findings highlight the potential of targeted CBD delivery systems for treating inflammation and supporting healing in the mouth.

“Cannabidiol (CBD), the primary bioactive element of cannabis, has shown promise in alleviating pain and inflammation, although mechanisms in periodontal inflammation are not fully understood.

To improve its limited solubility and mucosal permeability, the developed chitosan-based mucoadhesive hydrogel incorporating CBD-loaded PLGA nanospheres (CPN hydrogel) was characterized by FT-IR, SEM, particle size, rheological, swelling, and diffusion analyses, followed by biological evaluations, including wound-healing and RT-qPCR-based anti-inflammatory assays.

The improved CPN hydrogel had a homogeneous shape, better viscoelastic behavior, and sustained drug release. Over 90% of CBD was released within 96 h, and Franz cell experiments showed improved permeability (124.1 μg/cm2 after 72 h). The gellan gum-based mucosal substrate significantly increased adhesion (1137.33 ± 142.25 s) compared to the control groups.

Antioxidant studies indicated 73.65% DPPH radical scavenging, whereas antibacterial tests showed more than 99% suppression of Staphylococcus aureus. Furthermore, in vitro studies validated its wound healing and the downregulation of the inflammatory cytokines IL-6 and TNF-α.

The results indicate that the CPN-loaded chitosan hydrogel has extended mucosal retention, strong antibacterial activity, and steady release of CBD. This underscores its significant potential as a targeted treatment for inflammatory oral diseases such as gingivitis and periodontitis.”

“Cannabidiol (CBD), a non-psychoactive phytocannabinoid from Cannabis sativa with anti-inflammatory, immunomodulatory, and antimicrobial properties, is a promising bioactive compound for oral health applications [9,10,11]. In addition, CBD not only reduces inflammation, but also fights P. gingivalis very well.”

Development of smart/active chitosan/Kapppa-carrageenan films incorporating Aronia anthocyanin and ginger essential oil Pickering emulsion stabilized by hempseed protein nanoparticles

Posted on by

Hempseed protein is finding new uses as a functional ingredient in sustainable food-packaging technologies.

In this study, researchers used hempseed protein nanoparticles to stabilize a ginger essential-oil nanoemulsion incorporated into an edible film designed to both protect food and indicate freshness. The resulting material showed improved antioxidant and antimicrobial activity, stronger barrier properties, and color changes in response to conditions associated with spoilage.

The findings highlight hempseed protein’s potential role in developing bio-based “smart” packaging that can help preserve food while also signaling changes in freshness.

“The present study aimed to develop a multipurpose edible film with active (antioxidant/antimicrobial) and intelligent (food freshness monitoring) capabilities.

A Pickering nanoemulsion containing ginger essential oil (PNGEO) was prepared using hempseed protein as a stabilizer.

The effect of incorporating varying concentrations of PNGEO (0%, 5%, 10%w/v) and Aronia anthocyanin extract (AE) (0%, 4%, 8%w/v) on the physicochemical properties of films were evaluated using RSM and CCD, then optimal samples were identified using the utility function method, and their properties were examined.

The results demonstrated that the PNGEO formed a stable O/W emulsion with a Z-potential of -18.3 mV, a particle size of 108 nm, and PDI of 0.44. The encapsulation efficiencies were 91.72% for PNGEO. The AE exhibited pH-responsive color changes, transitioning from red to green across a pH range of 2-13. Increasing the AE and PNGEO enhanced the films’ water vapor barrier, antioxidant and antimicrobial properties. Elongation at break and tensile strength increased from 19.21% to 45.89% and from 6.25 to 15.97 MPa, respectively.

The pH color changes and sensitivity to ammonia gas confirmed the smart functionality of films. SEM and FTIR revealed minor changes in the chemical structure and strong molecular interactions between the biopolymer matrix and the incorporated components. XRD and DSC analyses indicated an increase in crystallinity index and a slight reduction in thermal stability. Release kinetics studies showed that higher temperatures and GEO content can increase the release rate and D values.

In conclusion, the film containing 8% AE and 10% PNGEO showed the best performance by simultaneously providing improvements in antioxidant/antimicrobial properties and sensitive color response to volatile spoilage compounds, and is introduced as a bio-based system with dual capabilities for maintaining quality and monitoring food freshness.”

Green Synthesis and Characterization of Nanographene-MnO Composite Nanoparticles for CO2 Capture: Adsorption Performance, Isotherm Analysis, and Reusability

Posted on by

Cannabis and hemp-derived materials are increasingly being explored in environmental technologies as well as medical and industrial research.

In this study, researchers developed nanographene–manganese oxide composite nanoparticles using a green synthesis approach and evaluated their ability to capture carbon dioxide. The material showed effective CO₂ adsorption, favorable adsorption behavior and reusability across repeated cycles.

The findings highlight the potential of plant-assisted nanomaterials for more sustainable carbon-capture technologies.

“In this study, hybrid composite nanoparticles (MnO-NG/green) containing nanographene (NG) and manganese oxide (MnO) were produced by using an environmentally friendly synthesis approach, and their CO2 adsorption performance was investigated in detail.

The conventional method was used to synthesize MnO-NG composites, which were then compared with MnO-NG/green composites prepared via green synthesis using bioextract from the hemp plant.

The composite nanoparticles were structurally characterized using various analytical methods, including FTIR, XRD, SEM, TEM, EDX, and BET analyses. The surface morphology of the composites obtained through green synthesis demonstrated a more homogeneous and regular distribution of MnO nanoparticles on the NG surface.

BET analysis revealed that the specific surface area of the MnO-NG/green composites was 629 m2/g, with a mean pore diameter of 4.65 nm. CO2 adsorption tests were conducted at 273 and 298 K under 1 bar, and it was determined that the MnO-NG/green composites achieved 5.81 and 4.94 mmol/g CO2 uptake capacities, respectively.

These values were significantly higher than those of NG (2.59-2.07 mmol/g) and conventional MnO-NG (4.43-3.74 mmol/g) composites. Analysis of the adsorption isotherm models indicated that the experimental data were better fitted by the Langmuir model. The calculated isosteric heat of adsorption (Q st, 19.4-24.5 kJ/mol) suggests that the adsorption of CO2 by MnO-NG/green composites predominantly occurs via physisorption. The MnO-NG/green composites demonstrated high structural stability and thermal resistance in five-cycle reusability tests, showing a reuse efficiency of 97%.

This study clearly demonstrates that the production of MnO-NG/green composite nanoparticles via a green synthesis offers a promising approach.”

https://pubmed.ncbi.nlm.nih.gov/42110753

“This study provides a strong demonstration of the successful production of nanographene-manganese oxide (NG-MnO) composite nanoparticles via an environmentally friendly green synthesis method and of the use of this structure as a high-performance adsorbent for CO2 capture applications. Superior properties were exhibited by MnO-NG/green composites produced using bioextracts from the hemp plant”

“In conclusion, the achievement of sustainable material production through a green synthesis approach with low environmental impact is not the study’s only accomplishment. The development of a high-performance, reusable, and environmentally friendly adsorbent that can contribute to the reduction of CO2 emissions is another. The resulting MnO-NG/green nanocomposites could be used in many different ways, from in the lab to in industry, which makes them a good choice for next-generation adsorbents in carbon capture technologies.”

Plant-derived neuroprotective compounds and nanoformulations targeting Parkinson’s disease: a semi-systematic review of mechanisms and therapeutic potential

Posted on by

Plant-derived compounds are being studied for their potential to protect brain cells from the processes involved in Parkinson’s disease, including oxidative stress, inflammation, mitochondrial dysfunction and abnormal protein accumulation.

This review examines natural neuroprotective compounds and newer nanoformulations designed to improve their delivery to the brain. It highlights multiple plant-based candidates, including cannabis-derived compounds, that may influence pathways involved in neuronal survival and disease progression.

The findings point to growing interest in combining natural bioactive compounds with nanotechnology to develop more effective strategies for Parkinson’s disease.

“Parkinson’s disease (PD) is a progressive neurodegenerative disorder characterized by aggregates of α-synuclein and the degeneration of dopaminergic neurons in the substantia nigra. Current pharmaceutical therapies mainly alleviate symptoms without halting disease progression.

Evidence suggests that traditional plant-based interventions may serve as supplementary therapies by targeting oxidative stress, mitochondrial dysfunction, neuroinflammation, and apoptosis.

This review explores the neuroprotective properties of ten medicinal plants commonly used in traditional medicine: Bacopa monnieri, Curcuma longa, Mimosa pudica, Zingiber officinale, Ocimum sanctum, Emblica officinalis, Camellia sinensis, Cannabis sativa, Panax ginseng, and Withania somnifera. A systematic and comprehensive search of PubMed, Scopus, and Web of Science identified relevant in vitro, in vivo, and clinical studies.

This study highlights the mechanisms by which plant-derived chemicals influence cellular pathways associated with PD, emphasising their therapeutic potential despite limited clinical validation.

Studies have shown that bioactive compounds such as curcumin, bacoside, Epigallocatechin-3-gallate (EGCG), cannabidiol, ginsenosides, and withanolides exhibit antioxidant, anti-inflammatory, anti-apoptotic, and neuroprotective effects in PD models.

Nanotechnology offers promising strategy to enhance the efficacy of herbal compounds, addressing challenges of poor solubility, rapid metabolism, low bioavailability, and restricted blood-brain barrier penetration. Nano-delivery systems including liposomes, polymeric nanoparticles, nanoemulsions, and metal nanoparticles can improve stability, brain targeting, controlled release, and cellular uptake of these bioactives, thereby enhancing therapeutic efficiency while reducing systemic toxicity.

Green-synthesized plant-based nanoparticles further provide synergistic neuroprotective benefits, positioning phyto-nanomedicine as a multi-target approach for PD therapy. However, extensive clinical studies are required to confirm safety and effectiveness.”

Phytochemistry-Guided Green Synthesis of Antimicrobial Silver Nanoparticles from Cannabis sativa Chemovars

Posted on by

Cannabis sativa contains a diverse mixture of phytochemicals that may also be useful in the development of antimicrobial materials.

In this study, researchers used extracts from different cannabis chemovars to guide the green synthesis of silver nanoparticles and examined how differences in plant chemistry influenced nanoparticle formation and biological activity.

The resulting nanoparticles showed antimicrobial potential, highlighting how cannabis-derived compounds may serve as natural reducing and stabilizing agents in the development of new bioactive nanomaterials.

“The phytochemical variability in Cannabis sativa L. chemovars represents an underexplored factor in environmentally sustainable nanomaterial production.

In this study, three distinct chemovars, (i) High-Δ9-Tetrahydrocannabinol (THC) (89% THC), (ii) Balanced (60% Cannabidiol (CBD)), and (iii) High-CBD (89% CBD), were comparatively evaluated to determine their suitability for the green synthesis of silver nanoparticles (AgNPs).

Ethanolic inflorescence extracts were used to recover bioactive secondary metabolites; among them, the High-CBD extract exhibited the highest total phenolic (3.34 mg gallic acid equivalent/g) and flavonoid (29.49 mg quercetine equivalent/g) contents, together with superior antioxidant capacity (53.16% 2,2-diphenyl-1-picrylhydrazyl free radical (DPPH) inhibition), indicating enhanced redox potential for nanoparticle formation. The terpene profile of High-CBD showed a dominance of myrcene (21.4%), contributing to the stabilization of the system.

Using the High-CBD extract, predominantly spherical nanoparticles of 5 ± 0.9 nm were synthesized and confirmed by UV-vis, EDS, and TEM. The biogenic AgNPs demonstrated significant dose-dependent antibacterial activity, with minimum bactericidal concentration (MBC) of 1.0 mg/mL against Staphylococcus aureus and 4.5 mg/mL against Escherichia coli.

These findings highlight the critical role of chemovar-dependent phytochemical composition and support a phytochemistry-guided approach for developing silver nanoparticles with potential biomedical applications.”

https://pubmed.ncbi.nlm.nih.gov/42123299

“This approach pursues to emphasize the relevance of full-spectrum compositions in cannabis extracts, particularly considering the reported ‘entourage effect’, where synergistic interactions among metabolites may enhance biological activity.”

“As a recognized medicinal plant, utilizing these inflorescence-derived compounds imparts an intrinsic therapeutic ‘added value’ to the nanoparticles.”

“By leveraging the synergistic potential between the plant’s bioactive constituents … and the antimicrobial silver core, this method offers an enhanced potential for biomedical applications compared to traditional chemical synthesis.”

“The successful synthesis of small, stable, and biologically active silver nanoparticles using the High-CBD extract underscores the potential of phytochemistry-guided strategies in advancing green nanotechnology for biomedical applications.”

Antimicrobial Agents in Fibrous Materials: A Comprehensive Review of Natural, Inorganic, and Organic Systems

Posted on by

Fibrous materials are increasingly being engineered to do more than provide structure—they can also be designed to resist microbial growth.

This review examines natural, inorganic and organic antimicrobial agents used in fibers and textiles, including plant-derived materials such as hemp. It explores how these agents are incorporated into fibrous systems and how they may help create surfaces with antibacterial and other protective properties.

The review highlights the growing role of bio-based fibers and antimicrobial technologies in developing safer, more functional materials.

“The escalating threat of antimicrobial resistance has spurred extensive research into antimicrobial fibers.

While numerous reviews have comprehensively cataloged the classification and mechanisms of natural, inorganic, and organic antimicrobial agents, a critical gap remains: few have systematically evaluated the engineering strategies that translate intrinsic biocidal activity into durable, real-world fiber performance.

This review addresses this gap by shifting focus from encyclopedic enumeration to a problem-oriented critical assessment of performance optimization strategies. We examine recent advances in natural fibers (bamboo, hemp, chitosan, jute) and synthetic fibers modified with antimicrobial agents, with emphasis on three core challenges-poor wash durability of natural agents, aggregation and leaching of inorganic nanoparticles (e.g., Ag, ZnO, MOFs), and structural limitations of organic agents (e.g., QACs, QPSs, N-halamines, PHMB). Key optimization routes, including covalent grafting, microstructural control (e.g., triaxial microfluidic spinning), organic-inorganic hybridization, and rechargeable N-halamine systems, are critically assessed for their effectiveness in enhancing washing resistance, stability, and antimicrobial synergy.

Based on this comparative synthesis, we identify future directions-smart-responsive systems, sustainable processing pathways, and standardized evaluation protocols-to guide the rational design of next-generation high-performance antimicrobial fibers.”

“Zhao and colleagues successfully converted seed-type hemp into regenerated cellulosic fibers through sequential degumming, pulping, and spinning processes”

“The resultant fibers exhibited significant antimicrobial effectiveness”

“The observed antimicrobial effects are primarily attributed to cannabinoids and their derivatives.”

“As global healthcare and sustainability challenges change, antimicrobial fibers are set to be crucial components in innovative solutions for public health protection and advanced material applications.”

Collective weak interactions of formic acid with hemp protein: Mechanism and application in Pickering emulsion stabilization

Posted on by

Hemp protein is being explored as a functional ingredient in advanced food and material systems, but its performance depends heavily on how it interacts with other molecules.

In this study, researchers examined how formic acid interacts with hemp protein and how those interactions influence the protein’s structure, solubility and ability to stabilize Pickering emulsions.

The findings help explain how hemp protein can be modified to improve emulsion stability, supporting its potential use in food, pharmaceutical and other formulation technologies.

“Anti-solvent precipitation using formic acid (FA, 0-98%, v/v) was developed to fabricate hemp protein nanoparticles (HPNs) for Pickering emulsion stabilization.

FA ≥10% (v/v) increased hemp protein solubility from 38.0% to 86.9% by solubilizing storage globulins, yielding HPNs with tunable sizes (100-780 nm), high ζ-potentials (>30 mV), and adjustable contact angles (57.7°-126.6°).

HPNs prepared at 40% FA exhibited optimal interfacial properties, including the lowest interfacial tension and highest emulsifying activity index (∼1800 m2/g), forming Pickering emulsions with 3-week stability and solid-like rheology.

Spectroscopic analysis revealed concentration-dependent conformational changes: invariant Raman spectra confirmed intact primary bonds, while fluorescence and UV-vis indicated initial unfolding (10-40%) followed by refolding (50-98%), and FT-IR showed that β-sheet content peaked at 61% (40% FA), which correlated with optimal interfacial performance.

Molecular dynamics simulations elucidated a dynamic “besieging effect” where numerous FA molecules collectively disrupted edestin’s hydrogen-bond network via weak interactions (binding energy -3.1 kcal/mol), inducing transient conformational expansion.

This work demonstrates the feasibility of FA as a solvent system for hemp protein nanoparticle fabrication and provides mechanistic insights into unconventional protein-solvent interactions, offering a foundation for future food-grade applications.”

Rethinking Punitive Responses to Underage Marijuana Use in the Era of Legalization: Insights from an Online Survey

Posted on by

As cannabis legalization expands, questions remain about how society should respond when minors possess, use or attempt to purchase marijuana.

This study surveyed more than 1,500 U.S. registered voters about penalties and interventions for underage cannabis-related behavior. Respondents generally showed stronger support for parental notification, community service and drug education than for jail time, while support varied depending on the specific offense.

The findings provide a snapshot of public attitudes toward balancing accountability, prevention and punishment in the legalization era.

“Background: As adult nonmedical marijuana use becomes legal in many U.S. states, policymakers have adopted a range of responses to underage marijuana-related behaviors, often emphasizing punitive consequences. The extent to which these approaches align with public preferences remains unclear.

Methods: Data were drawn from an online survey of 1502 U.S. registered voters recruited from a national opt-in online panel. Analyses assessed support for a range of consequences for underage marijuana-related behaviors (i.e., possession, use, sale, and use of false identification), with selected bivariate comparisons across demographic groups.

Results: Respondents supported penalties for using false identification (89%) and selling marijuana (84%); fewer supported penalties for possession (59%) or use (57%). For attempted purchases, parental notification (79%), community service (64%), and drug education (58%) were more commonly endorsed than jail time (18%). Several differences by age, sex, race/ethnicity, and parent status were observed.

Conclusions: Respondents generally expressed greater support for parental notification, community service, and education as a response to underage violations of marijuana laws than for punitive responses. Policies that emphasize supportive, health-oriented responses, alongside stronger adult and industry accountability, may be more consistent with public attitudes and more effective than punitive responses in advancing youth protection goals in legalized contexts.”

Multiple binding modes underlie Cannabis sativa cannabinoids recognition by peroxisome proliferator-activated receptor gamma

Posted on by

Cannabinoids interact with more than the classical cannabinoid receptors CB1 and CB2. One important target is PPARγ, a nuclear receptor involved in metabolism, inflammation, insulin sensitivity and several disease-related pathways.

In this study, researchers examined how multiple Cannabis sativa cannabinoids bind to and activate PPARγ. The results showed that different cannabinoids can engage the receptor through multiple binding modes, with acidic cannabinoids such as THCA and CBDA showing particularly strong activity.

The findings help clarify another molecular pathway through which cannabis compounds may influence biological processes relevant to metabolic, inflammatory and other disorders.

“Introduction: Peroxisome proliferator-activated receptor gamma (PPARγ) is a ligand-activated nuclear receptor with broad therapeutic relevance across various pathologies, including type 2 diabetes, obesity, cancer, and inflammatory disorders. Cannabinoids are a class of terpene-phenolic compounds from Cannabis sativa L. that have been shown to act as partial agonists of PPARγ. Among them, the acidic forms Δ9-tetrahydrocannabinolic acid (THCA) and cannabidiolic acid (CBDA) display higher potency than their decarboxylated counterp arts Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD). Despite experimental evidence supporting direct PPARγ-cannabinoid interaction, the molecular determinants governing ligand recognition within the binding pocket have not yet been comprehensively investigated.

Methods: A combination of molecular docking and molecular dynamics simulations was employed to characterize the binding modes of THC, CBD, THCA, and CBDA within the PPARγ ligand-binding domain. Docking calculations were performed on a curated set of 70 PPARγ crystal structures co-crystallized with structurally diverse ligands, exploiting thus the conformational variability of the binding pocket. The best-ranked solutions were subjected to 500 ns MD simulations and evaluated on the basis of ligand stability, persistence of polar and aromatic-aromatic interactions with the receptor, and energetic contributions estimated by MM/GBSA. Three candidate binding modes per ligand were selected and their trajectories extended to 1,000 ns.

Results: All four cannabinoids yielded at least one stable binding mode at the microsecond timescale. The cannabinoids THCA and CBDA displayed a greater number of stable binding modes than THC and CBD, a result consistent with the higher potency previously reported for these compounds in experimental studies. This behavior may be attributable to the formation of salt bridges with basic residues in the binding pocket.

Conclusion: Our findings provide a structural framework for understanding cannabinoid recognition by PPARγ. The ability of these compounds to adopt multiple binding modes may contribute to their partial agonist profile, opening new avenues for the rational design of selective PPARγ modulators with improved therapeutic properties.”

https://pubmed.ncbi.nlm.nih.gov/42639023

“This work provides a foundation for future studies addressing the molecular basis of cannabinoid action on PPARγ.

Moreover, these findings could serve as a starting point to explore the allosteric mechanism by which these small lipophilic molecules influence receptor structure and dynamics.

Finally, the strategy described here may also be applied to determine the binding modes of these natural compounds in other members of the nuclear receptor family, including PPARα and PPARδ, as well as to investigate the binding modes of minor cannabinoids, such as cannabichromene and cannabigerol.”

Long-term experiences of patients prescribed medicinal cannabis in Australia: a qualitative interview study 

Posted on by

As medicinal cannabis becomes more widely prescribed, long-term patient experiences can help show how it is actually being used outside controlled clinical trials.

In this Australian qualitative study, researchers interviewed patients who had been prescribed medicinal cannabis for chronic conditions and explored their experiences with symptom relief, side effects, treatment decisions and everyday use.

Participants commonly described improvements in symptoms such as pain, anxiety, spasticity, insomnia and depression, providing real-world insight into the perceived benefits and challenges of longer-term medicinal cannabis treatment.

“There is limited, but emerging, evidence supporting the use of medicinal cannabis (MC) to manage pain, anxiety, spasticity, insomnia and depression. Although Australian legislation changed in 2016 to provide access to unapproved MC products, clinical guidance on prescribing MC is limited because it is still mostly an unapproved therapy accessed under strict conditions. Since legislation changed, little is known about the long-term lived experience of patients being prescribed unapproved MC products in Australia. We aimed to explore, and obtain an in depth understanding of, the long-term experiences of patients prescribed MC.

Using an interpretive qualitative approach, participants were recruited from the Quality-of-Life Evaluation Study, a nationwide longitudinal study of patients with any chronic health condition prescribed orally administered MC oil over 1 year. Semi-structured interviews explored experiences of accessing and using MC during and since completing the Quality-of-Life Evaluation Study. Thematic analysis identified themes and subthemes from the data.

Results

Fifteen participants aged 33–78 years (nine female) who had completed the Quality-of-Life Evaluation Study and renewed MC oil prescriptions within the previous 6 months to manage chronic pain, insomnia, muscle spasticity, anxiety or depression were interviewed. Analysis identified four overarching themes: ‘This isn’t living’; ‘I was looking for a solution’; ‘It wasn’t to get high’; and ‘Everything’s much better’, and eight subthemes covering concerns, barriers, patient autonomy and benefits. Participants commonly used MC to reduce or replace conventional medications taken for their conditions, and viewed MC as a low-risk ‘natural’ alternative. Barriers to accessing MC included difficulties obtaining prescriptions and the cost of MC products. Participants reported symptom improvements that flowed on to benefit relationships, productivity and mental health over the long term. Although initially concerned about side-effects, participants self-managed these effectively, with perceived benefits outweighing side-effects. Participants described roadside drug testing as an ongoing concern.

Conclusions

This group of patients prescribed orally administered MC oil in Australia reported many benefits of MC, but faced ongoing barriers to MC access. Improved awareness and education, simplified prescribing processes, and less prohibitive driving laws could lead to wider acceptance of MC as a therapeutic option and improved patient-centred care.”
