A polypeptide‐DNA hydrogel is prepared by Z. Li, D. Liu, and co‐workers, employing the “X”‐shaped DNA assembling structure as crosslinker. The hydrogel can be modified with multifunctional components (here fluorescent molecules as a model), and possess excellent self‐healing and thixotropic properties, enabling the direct‐writing of arbitrary 3D structures. The study on page 1138 provides a simple, universal strategy for the assembly of functionalized hydrogels with biomolecules, especially enzymes.
