Abstract

Abstract : A new hybrid hydrogel was constructed by in situ forming Ag NPs within the 3D network of a hydrogel that exhibits both excellent injectability and broad antibacterial activities, which makes it a potential candidate for various biomedical applications. Abstract : A new hybrid hydrogel was constructed by in situ forming silver nanoparticles (Ag NPs) within the 3D network of a hydrogel based on a tryptophan derivative containing a phenylcarbinol side group (HAIP), which was triggered by natural light, without the need of UV-irradiation or the addition of capping reagents. Remarkably, in addition to excellent thixotropy and injectability, the hybrid Ag NPs–HAIP hydrogel exhibits broad antibacterial activities without cell cytotoxicity, which makes it a potential candidate for various biomedical applications.
