英文摘要：

Abstract：In recent years, DNA nanotechnology has become a highly interdisciplinary research field, including such as life science, chemistry, physics, materials science and nanotechnology, and many other fields. Based on DNA self-assembly technology, people have constructed a series of molecular devices and materials. As a kind of smart and dynamic materials, supramolecular DNA hydrogels have potential applications in the biomedical field. This review highlights the recent important study about the self-assembled strategies, dynamic responsiveness and biomedical applications of supramoleeular DNA hydrogels.
