Figure 1From: Cell behaviour on a polyaniline nanoprotrusion structure surfaceSurface topography images and 3D image of a PANI nanostructure-coated TCP plate. (a) SEM front view, the scale bar represents 250 nm; the inset image is a side view in which the scale bar indicates 500 nm. (b) AFM 3D image of surface roughness; the scanned area was 6 × 6 μm.Back to article page
