Dynamic hydrogels produced via monoamine oxidase B-catalyzed deamination and aldimine crosslinking for 3D printing

Abstract

Dynamic hydrogels were prepared via an oxidative deamination reaction catalyzed by monoamine oxidase B. Amino-containing polysaccharides (or proteins) and oxidative products (aldehydes) formed the dynamic Schiff base linkages, which endowed the hydrogel with excellent self-healing and multiresponsive properties.
