Abstract
A novel supramolecular DNA hydrogel system was designed based on a directly synthesized chemically branched DNA. For the hydrogel formation, a self-dimer DNA with two sticky ends was designed as the linker to induce the gelation of B-Y. By programing the linker sequence, thermal and metal-ion responsiveness could be introduced into this hydrogel system. This supramolecular DNA hydrogel shows shear-thinning, designable responsiveness, and good biocompatibility, which will simplify the hydrogel composition and preparation process of the supramolecular DNA hydrogel and accelerate its biomedical applications.
