Abstract
This work developed a G‐quadruplexes‐based hydrogel consisting of guanine and peptide epitope to form a supramolecular hydrogel in the presence of metal cations. Using the metal ion‐responsive peptide epitope from the ion channel to replace sugar motif at N9 position of guanosine results in a novel nucleopeptide. The results show that the gelation time, the diameter of nanofibers, the anisotropic property, and the mechanical property of the nucleopeptide hydrogel can be simply controlled using metal cations. This work may provide a strategy for gluing pre‐existing fibers to form a hydrogel with tailored structures. More details are discussed in the article by Wang et al. on page 1727—1732.image
