Cell fate on different nanostructured conducting polymer PPy substrates. (A) Immunofluorescence stained bone forming cells after the cells were cultured on TCA-doped PPy nanotubes in their original state (a), potential-off states (b, d and f) and potential-on states (c, e and g); (B) Schematic and SEM image of cells on an oxidized and reduced PPy nanoarrays. The cells on oxidized PPy nanoarrays presented more and longer filopodia. They began to detach from the nanoarrays when the nanoarrays were reduced.
