biomaterials that encourage cell alignment. Materials & methods: Thin conducting composite
biomaterials based on multilayer films of poly (3.4-ethylenedioxythiophene) derivatives,
chitosan and gelatin were prepared in a layer-by-layer fashion. Fibroblasts were observed
with fluorescence microscopy and their alignment (relative to the dipping direction and
direction of electrical current passed through the films) was determined using ImageJ …
