Abstract
A long-lasting hydrogel for use against drug-resistant bacteria, and a preparation method and use thereof are provided. In the present disclosure, polyvinyl alcohol (PVA) is mainly adopted as a matrix, and phytic acid and honey including glucose and fructose are added to modify the PVA to obtain the hydrogel. During preparation of the antimicrobial hydrogel, no toxic chemical crosslinking agent or initiator is added, and the antimicrobial hydrogel is mainly obtained by crosslinking PVA, phytic acid, and monosaccharides through ester bonds, hydrogen bonds, and electrostatic adsorption. In addition, the hydrogel obtained by adding phytic acid and honey to the PVA matrix exhibits a significant long-lasting antimicrobial effect for(), drug-resistant, and(), and the antimicrobial effect can last for about 3 months.
