Wound dressing materials were obtained from gelatin, chitosan and nanoSiO2particles as filler. The barrier property to water vapor, water uptake ratio and antimicrobial properties of the wound dressing materials were investigated. The addition of the nanoSiO2particles endowed the materials good water uptake ratio and the barrier property to water vapor, whereas the antimicrobial agents improve the barrier property producing more hydrogen bonds. Moreover, the networks of the wound dressing materials with nanoSiO2particles displayed excellent compound binding capacity could reduce the permeation of water and increase the antimicrobial effect of the materials. The antimicrobial agents endowed the wound dressing materials with antimicrobial effect.

Wound healing remains as a dynamic process and the type of dressing material significantly affects the efficacy of healing. The identification of ideal dressings to use for a particular wound type is an important requisite facilitating the entire process of healing. Chronic, high exudate wounds are dynamic in presentation and remain as a major health care burden. Researchers have sort to design and optimize biodegradable wound dressings that focuses to optimize moisture retentiveness, as superior character in the healing process. In addition, dressings have been designed to visualize the wound bed by improving the optical property, target and kill infection-causing bacteria, with the incorporation of antimicrobial agents, nanomaterials and numerous other measures. For the practitioners, choosing the optimal dressing decreases time to healing, provides cost-effective care and improves patient quality of life. The current mini review highlights the ideal characters of wound dressing materials and presents insights on the superior characters of carrageenan bio composites for prospective advancements in research in the area of wound care and management.

One approach to develop innovative antimicrobial wound dressing materials is to use natural polymers loaded with antimicrobial agents. The valorisation of animal proteins as biomaterials with antimicrobial properties is a new concern for development of wound healing. Plant esssential oils (EO) also indicate a potential approach for new wound dressing materials able to replace the synthetic antymicrobial agents. In this paper, plant-polymeric film was prepared by casting film-forming emulsion based on lemongrass (Cymbopogon flexuosus) essential oil/Tween 80 dispersed into rabbit collagen glue hydrolysate– chitosan biomaterial. The effect of biomaterial film composition on Staphylococcus aureus ATCC 6538 and Escherichia coli ATCC 10536 standard bacteria, and Candida albicans ATCC 10231 pathogenic fungus was studied according to European Pharmacopoeia 10/2020 as compared with biomaterial film without essential oil. The in vitro antibacterial tests against three bacterial strains showed that the rabbit collagen glue hydrolysate–chitosan biomaterial inhibited all the three microorganisms. The rabbit collagen hydrolysate glue-chitosan film loaded with lemongrass essential oil exhibits antimicrobial activity towards tested microorganisms but lower as compared with control. The explanation could be due to the short time of investigation, or maybe some active compounds constituents of EO, which favour the cellular proliferation. Preparation of rabbit collagen glue hydrolysate-chitosan biomaterial loaded with lemongrass essential oil is an environmentally friendly solution, which may contribute to the development of wound healing materials as an alternative to topical antimicrobial agents.
