A Writable Polypeptide–DNA Hydrogel with Rationally Designed Multi‐modification Sites

Abstract

A polypeptide-DNA hydrogel is prepared by employing the “X”-shaped DNA assembling structure as crosslinker. The hydrogel can be modified with multifunctional components (here fluorescent molecules as a model) and possesses excellent self-healing and thixotropic properties, enabling the direct-writing of arbitrary 3D structures. This study provides a simple, universal strategy for the assembly of functionalized hydrogels.
