1. An Injectable CMCS/γ-PGA/PRP Bioadhesive With Antibacterial, Adhesive, and Regenerative Properties for Infected Wound Healing.
An injectable CMCS/γ-PGA/PRP bioadhesive (CγR) integrates antibacterial, adhesive, and regenerative functions. It sterilized infected wounds, enabled >3 kPa wet adhesion, sustained growth factor release, achieved full epithelialization within 6 days in rats, enhanced collagen deposition, and promoted M2 macrophage polarization.
Impact: By condensing suture-antibiotic-dressing into a one-step, biosafe platform with strong in vivo efficacy, this work could shift management of contaminated wounds and cosmetic outcomes after trauma or procedures.
Clinical Implications: If validated in humans, a single-application bioadhesive could reduce infection risk, procedure time, and scarring in contaminated lacerations and surgical wounds, including aesthetic procedures.
Key Findings
- CγR achieved >99.9% bactericidal efficacy against E. coli and S. aureus.
- Instantaneous wet-tissue adhesion exceeded 3 kPa.
- Sustained gradient release of PDGF, TGF-β, and VEGF was demonstrated.
- Infected rat full-thickness wounds showed sterile sealing and complete epithelialization within 6 days after a single application.
- Collagen deposition increased 1.5-fold and macrophages polarized toward an M2 prohealing phenotype.
Methodological Strengths
- Rational compositional tuning of CMCS/PRP/γ-PGA with quantitative adhesion and bactericidal assays.
- In vivo validation in an infected full-thickness rat wound model with histologic and immunophenotypic readouts.
Limitations
- Preclinical animal data without human clinical validation.
- Short-term, single-application outcomes; long-term durability, safety, and PRP variability were not assessed.
Future Directions: Conduct dose-ranging and comparator-controlled human trials across contaminated wound types; standardize autologous PRP content; evaluate manufacturing scalability and regulatory pathways.
Infected traumatic wounds remain a formidable clinical challenge because existing bioadhesives provide only tissue adhesion and lack concurrent antimicrobial and regenerative capabilities. Here, we developed an injectable bioadhesive (CγR) that integrates an "antibacterial-adhesive-regenerative" (AAR) triad by precisely tuning the ratio of carboxymethyl chitosan (CMCS), autologous platelet-rich plasma (PRP), and γ-polyglutamic acid (γ-PGA). CγR exhibits > 99.9% bactericidal efficacy against Escherichia coli and Staphylococcus aureus, delivers instantaneous wet-tissue adhesion (> 3 kPa), and sustains a gradient release of PDGF, TGF-β, and VEGF. In a rat model of infected full-thickness wounds, a single application achieved sterile sealing and complete epithelialization within 6 days, increased collagen deposition by 1.5-fold, and markedly drove macrophage polarization toward the prohealing M2 phenotype. By condensing the conventional "suture-antibiotic-dressing" regimen into a one-step procedure, CγR offers a biosafe and readily scalable platform for managing contaminated complex wounds and holds promise for clinical translation.
2. Botanical and Upcycled Bioactives for Advanced Topical Formulations: Mechanistic Pathways, Cutaneous Delivery, and Sustainability-by-Design.
This narrative review synthesizes molecular mechanisms of botanical actives with state-of-the-art delivery platforms (e.g., nanoemulsions, SLNs/NLCs, microneedles, PDEVs) and embeds sustainability-by-design (upcycling, green extraction, LCA). It proposes a translational framework linking phytochemistry, delivery science, safety, and circularity for rational topical formulation development.
Impact: By integrating mechanistic dermatology, delivery science, and sustainability into a unified framework, the paper guides evidence-based development of effective and greener topical products beyond ingredient catalogues.
Clinical Implications: Supports rational selection and delivery of botanicals for skin regeneration, pigmentation control, and barrier support while aligning with regulatory and sustainability requirements.
Key Findings
- Botanical actives modulate oxidative stress, inflammation, ECM remodeling, pigmentation, and immune pathways relevant to skin homeostasis.
- Advanced delivery systems (nanoemulsions, SLNs/NLCs, vesicles, microneedles, 3D matrices, PDEVs) improve cutaneous bioavailability, controlled release, and targeting.
- Sustainability-by-design (upcycling by-products, green extraction, biodegradable packaging, life cycle assessment) is reshaping cosmetic innovation.
- A translational framework links phytochemistry, delivery science, safety-by-design, and sustainability for topical dermatology.
Methodological Strengths
- Mechanistically oriented synthesis linking formulation attributes to exposure–response relationships.
- Structured literature search with integration of delivery technologies and sustainability considerations.
Limitations
- Narrative review design; not a PRISMA-compliant systematic review.
- Heterogeneity of source studies precludes quantitative synthesis and may introduce selection bias.
Future Directions: Standardize botanical extracts, define bioequivalence metrics, and conduct controlled clinical trials; embed circularity metrics and regulatory harmonization in product development.
Natural and sustainable cosmetics represent a rapidly evolving frontier in dermatological science, integrating plant-derived bioactive compounds with advanced delivery technologies and environmentally conscious formulation design. Botanical ingredients, including polyphenols, flavonoids, terpenoids, alkaloids, and polysaccharides, modulate key biological pathways involved in oxidative stress, inflammation, extracellular matrix remodeling, pigmentation, and immune responses, thereby supporting skin regeneration, protection, and homeostasis. To overcome limitations related to instability, compositional variability, and limited skin penetration, these compounds are increasingly incorporated into advanced delivery systems such as nanoemulsions, solid lipid nanoparticles (SLNs), nanostructured lipid carriers (NLCs), vesicular systems, microneedle platforms, three-dimensional matrices, and plant-derived extracellular vesicles (PDEVs). These technologies enhance cutaneous bioavailability, enable controlled release, and improve tissue targeting, linking formulation design to exposure-response relationships. In parallel, sustainability has become a critical component of product development. Circular economy strategies, including the upcycling of agro-industrial by-products, green extraction technologies, biodegradable packaging, and life cycle assessment, are reshaping cosmetic innovation. Regulatory frameworks are also evolving to address safety, efficacy, and transparency of natural claims, as well as the challenges of botanical standardization. This narrative review, conducted through a structured literature search, provides a mechanistically oriented analysis of botanical ingredients in dermatology, emphasizing molecular pathways, skin delivery science, and safety considerations. Rather than cataloguing ingredients, it proposes a translational framework linking phytochemistry, delivery science, safety-by-design principles, and sustainability to support the rational development of effective and safe dermatological formulations.
3. Impact of Semi-Permanent Nail Polish on Forensic DNA Profiling and Phenotyping from Fingernails.
Semi-permanent nail polish significantly reduces DNA recovery, especially with repeated use, yet does not compromise STR typing for personal identification. Mixed STR profiles occurred in 28.6% of samples, and MPS-based forensic DNA phenotyping was feasible when DNA quantity was adequate and single-source profiles were obtained.
Impact: Provides practical evidence guiding forensic workflows when cosmetic nail treatments are present, balancing decontamination with preservation of evidentiary value.
Clinical Implications: Forensic and clinical laboratories should continue to consider fingernails with semi-permanent polish as viable DNA sources; protocols may need optimization to manage reduced yield and mixed profiles.
Key Findings
- Semi-permanent nail polish, particularly with repeated application, significantly reduced DNA recovery.
- STR typing for personal identification was not affected despite reduced DNA yield.
- Mixed STR profiles were observed in 28.6% of samples, indicating incomplete removal of foreign DNA by washing.
- Forensic DNA phenotyping by MPS was successful in nails with adequate DNA quantity and single-source profiles.
Methodological Strengths
- Prospective sample collection from volunteers across usage patterns (new, occasional, regular).
- Use of both STR profiling and MPS-based forensic DNA phenotyping.
Limitations
- Modest sample size and controlled setting; brand/formulation variability not fully explored.
- Nail washing protocol may not generalize; real-world degraded samples were not assessed.
Future Directions: Standardize decontamination protocols, compare different polish brands/removers, and validate in larger, real-world datasets including degraded remains.
BACKGROUND/OBJECTIVES: The increasing global trend in nail beautification may lead to analyses of nails with semi-permanent polish for the identification of degraded human remains. This study aimed to evaluate the effects of cosmetic nail treatment on forensic STR DNA profiling and phenotyping of eye, hair, and skin colour characteristics using a massively parallel sequencing (MPS) assay. METHODS: Forty-two nail samples obtained from 21 volunteers, classified in "new", occasional and regular semi-permanent polish users, were submitted to DNA analysis. RESULTS: The use of semi-permanent nail polish, particularly when applied repeatedly, resulted in a significant reduction in DNA recovery, but it did not affect STR typing for personal identification. Mixed STR profiles were observed in 28.6% of the samples, indicating that the nail washing procedure employed before DNA extraction did not completely remove the foreign DNA; however, this could be useful depending on the forensic context. FDP analysis was successfully applied on nails with semi-permanent polish that showed a good quantity of DNA and single-source profiles. CONCLUSIONS: The results highlight the evidentiary value of fingernails even if treated with semi-permanent nail polish that should still be regarded as a source of DNA for personal identification and further investigation in the forensic context.
