A photocrosslinked hybrid hydrogel based on chitosan/hyaluronic acid/ZnO toward wound sealing†
Abstract
A newly designed photocrosslinked hydrogel undergoes gelation under UV light irradiation and contains three types of crosslinked networks resulting from free radical polymerization, thiol-Michael addition reaction and dynamic disulfide bonds. This hybrid hydrogel exhibits an extremely fast gelling time, improved modulus and broad-spectrum antibacterial properties.
