Cell alignment on near-field electrospinning (NFES) fibers. (a) HEK 293T cells were seeded to PPy films, randomly deposited alginate fibers, or NFES alginate fibers deposited surfaces. The distribution and morphology of surface cells were observed by a phase contrast microscope (scale bar = 100 μm). (b) Cell images were analyzed by fast Fourier transform (FFT) to determine the levels of cell alignment.
