Anion‐π Interaction‐Triggered Self‐Healing Zwitterionic Hydrogel as an Immunocompatible Platform for Injectable Therapies
An injectable zwitterionic supramacromolecular hydrogel (SSH) is reported, formed by the spontaneous assembly of poly(methacryloyloyloxyethyl sulfobetaine) and poly(styrenesulfonate) (PSSNa), which exhibits injectability, self‐healing behavior, intrinsic antiadhesive properties, and favorable immunocompatibility.
