Background: Conventional wound dressings often adhere to wounds and can cause secondary injury due to their lack of anti-inflammatory and antibacterial properties. In contrast, collagen-based nanoparticles (NPs) as drug delivery systems exhibit both biocompatibility and biodegradability, presenting a promising avenue for accelerating wound healing processes.
Aims Of Study: This review aims to provide a comprehensive overview of the mechanisms involved in wound healing, description of the attributes of ideal wound dressings, understanding of wound healing efficacy of collagen, exploring NPs-mediated drug delivery mechanisms in wound therapy, detailing the synthesis and fabrication techniques of collagen-based NPs, and delineating the applications of various collagen-based NPs infused wound dressings on wound healing.
Nanochitosan is known to have the potential to protect fish fillets, highly perishable products, as it can penetrate deep into the meat tissue and has high antibacterial activity. This study aimed to analyze the effect of nanochitosan incorporation to edible coating in inhibiting the degradation of Pangasius fillet quality during storage. The fillets were soaked with 2 % chitosan and nanochitosan concentrations (1 %, 2 %, and 3 %), stored for 15 days, and its quality was assessed periodically.

- - The study explores the potential of using natural polymers like semi-refined iota carrageenan (SRIC) and fish gelatin (FG) to create eco-friendly food packaging films that replace conventional plastics.
- - Different ratios of SRIC and FG were tested, with the inclusion of SiO-ZnO nanoparticles, which enhanced the films' key properties like UV protection, antimicrobial activity, and mechanical strength.
- - The best-performing formulation was a 1.5:0.5% SRIC-FG film, indicating strong potential for these biocomposite films to reduce plastic waste and keep food fresh longer.
This paper reports the incorporation of cassava starch (CS) at various concentrations into a previously developed ZnO/SiO-semi-refined kappa carrageenan-based film (SRκC) bionanocomposite and evaluates its performance as minced chicken edible packaging. The incorporation of CS into SRκC-based films aims to provide multifunctional food packaging with enhanced surface morphology, thickness, mechanical properties, and transparency. The effect of the incorporation of various mixing ratios of CS and SRκC (CS:SRκC ratios of 1:3, 1:1, and 3:1) was investigated.
