Cell-compatible multi-functional crosslinker-based hydrogels for tissue engineering

Abstract

The thesis showed preliminary evaluation of novel biodegradable and biocompatible agmatine-containing PAA crosslinkers. Hydrogels fabricated by this crosslinker can obtain controllable stiffness and excellent cell adhesion. The PAA contained thermo-sensitive hydrogel reported here is first employed as filler for depressed defects in rats. Results showed that such hydrogel can be injectable and biocompatible, might become a new material in plastic surgery in the clinic. The thesis also demonstrated a novel macro gels with self-healing capability and biocompatibility. The reversible photodimerization and photocleavage reactivity of coumarin has been successfully imparted to the polymer.
