Abstract

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.
