Preparation of aligned PMGI fibers. (a) Schematic of electrospinning and transfer of electrospun nanofibers to the surface of a microelectrode array. The scale bar = 50 μm. (b) Angular distributions and (c) diameter of fibers generated from PMGI of different concentrations (%). (d) Scanning electron microscopy images of 16% PMGI fibers electrospun for 10, 90, and 300 s. The scale bar = 50 μm (means ± s.e., , , ).
