A multifunctional hydrogel dressing with high tensile and adhesive strength for infected skin wound healing in joint regions

Abstract

A multifunctional hydrogel dressing with high tensile and adhesive strength and photothermal antibacterial properties based on PVA, borax, TA and Fe3+ was developed for infected skin wound healing in joint regions.

The synergetic effect of alginate-derived hydrogels and metal–phenolic nanospheres for chronic wound therapy

“…Tannic acid, a natural branched water-soluble polyphenol, abundantly found in the leaves of the lacquer tree, possesses a diverse array of catechol moieties. 11 A large number of studies in the literature have highlighted its wide-ranging physicochemical activities, including its ability to interact with polysaccharides, proteins, and metal ions, 12,13 engage in reactions with alkaloids and enzymes, 14 and exhibit antioxidant, 15 antimicrobial, 16 and anti-inflammatory properties. 17 Moreover, tannic acid shows immense promise as an anticancer agent, 18,19 as it acts as a contact sensitizer by possessing diacetyl and gallic acid moieties, subsequently participating in signaling pathways crucial for tumor development.…”
