Injectable spontaneously formed asymmetric adhesive hydrogel with controllable removal for wound healing

Abstract

Healing large-scale wounds has been a long-standing challenge in the field of biomedicine. Here, we propose an injectable alginate/gelatin/3,3'-dithiobis(propionic hydrazide)-Aurum (Alg/gelatin/DTPH-Au) hydrogel filler with asymmetric adhesion ability and removability, which...
