Developing biointerfaces that combine the advantages of both monolithic and focal elements remains challenging. Now, a hydrogel that releases surface-modified granules and shows biointerface transition capability has been developed. This granule-releasing hydrogel manages colitis, accelerates wound healing, and facilitates cardiac tissue regeneration and mapping of cardiac activity with bioelectronic devices.
