Arrayed rGO_SH/PMA_SH Microcapsule Platform Integrating Surface Topography, Chemical Cues, and Electrical Stimulation for Three‐Dimensional Neuron‐Like Cell Growth and Neurite Sprouting

The biocompatible thiol‐functionalized rGO SH /PMA SH microcapsules encapsulating nerve growth factor (NGF) are arrayed onto a transparent and conductive substrate, i.e., indium tin oxide (ITO), to integrate electrically stimulated cellular differentiation, electrically controlled NGF release, and topographically rough nano‐surfaces into a 3‐D platform for nerve regeneration. The rGO SH /PMA SH microcapsules with microscale topography function...
