1. An Injectable CMCS/γ-PGA/PRP Bioadhesive With Antibacterial, Adhesive, and Regenerative Properties for Infected Wound Healing.
This preclinical study reports a tri-functional injectable CMCS/γ-PGA/PRP bioadhesive achieving >99.9% bacterial kill, rapid wet-tissue adhesion, and sustained growth factor release. In infected rat wounds, one application produced sterile sealing and full epithelialization by day 6 with enhanced collagen deposition and M2 macrophage polarization.
Impact: Condensing suture, antibiotics, and dressing into a single bioadhesive platform could streamline care for contaminated wounds and reduce complications. The mechanistic integration of antimicrobial action and pro-regenerative signaling is a notable advance.
Clinical Implications: If validated in humans, this bioadhesive could provide a one-step alternative for managing contaminated traumatic and surgical wounds in plastic and reconstructive settings, potentially lowering infection rates and accelerating healing.
Key Findings
-
99.9% bactericidal efficacy against Escherichia coli and Staphylococcus aureus
- Instantaneous wet-tissue adhesion exceeding 3 kPa
- Sustained gradient release of PDGF, TGF-β, and VEGF
- Infected rat wounds achieved sterile sealing and complete epithelialization within 6 days
- 1.5-fold increase in collagen deposition and M2 macrophage polarization
Methodological Strengths
- Rational biomaterial design with defined component ratios (CMCS, PRP, γ-PGA)
- In vivo validation in an infected full-thickness wound model with multimodal readouts
Limitations
- Preclinical animal data without human clinical validation
- Long-term safety, biofilm robustness, and head-to-head comparisons with standard of care are not reported
Future Directions: Conduct GLP toxicology, dose-ranging, and randomized clinical trials in contaminated traumatic and surgical wounds; evaluate performance against polymicrobial biofilms and in immunocompromised hosts.
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.

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.

Collagen is the most abundant structural and functional protein in humans and other vertebrates. It possesses remarkable biological functions and is widely used in food, cosmetics, and healthcare. Currently, mainstream animal-derived collagen materials carry risks such as viral transmission and allergic reactions. However, recombinant collagen, heterologously expressed using genetic recombination technology combined with high-density fermentation processes, offers greater biocompatibility, low immunogenicity, and consistent quality, offering promising development prospects. However, current research on recombinant collagen still faces challenges such as low yield and poor functionality. This article briefly describes the structure, types, and functions of collagen, discusses the advantages and limitations of different recombinant collagen expression systems, and highlights the strategies for improving the yield and optimizing the function of recombinant collagen, ranging from gene editing to fermentation optimization. In highlighting practical approaches to achieving high yield, we present a series of case examples to illustrate the successful application of these principles. This review aims to help researchers, engineers, and industry practitioners better understand research trends in the expression and production of recombinant collagen, and to promote its further development and commercialization across diverse application areas.
