Fig. 1. Formation of an adaptable conductive microporous hydrogel (CMH).

a Schematic illustration of monodispersed gelatin methacrylamide (GelMA) injectable building blocks (microbeads, MBs) formation (upper); the process of synthesizing cys-GYB (lower). b Schematic illustration of injectable and reversible CMH. c Fluorescence image of a cell-laden micronetwork scaffold. Scale bar: 100 μm. d Schematic illustration of eddy current induced by HFMF (left) and promote BDNF releasing (right). e A photograph image represents the characteristic of injectable CMH into irregular cavity. Scale bar: 1.5 mm. f Schematic illustration of CMH with an electrical stimulation and axonal neurofiliments regrow in vivo.
