Abstract
DNA supramolecular hydrogels are hydrogels cross-linked through DNA hybridization. They have attracted wide attention due to their great molecular permeability, biocompatibility, degradability, thixotropy, and self-healing properties, which make them very useful in cell culture, tissue engineering, and 3D printing. The designability and responsiveness of DNA endows these hydrogels with specific stimuli responsiveness, thus enhancing their utility for more applications, e.g., detection devices and shape-memory materials. In this review, we outlined and discussed the development of responsive DNA supramolecular hydrogels, and their applications have also been summarized.
