Figure 5From: Cell behaviour on a polyaniline nanoprotrusion structure surfaceTotal DNA quantities in MC3T3-E1 cells at 1, 3, 5 and 7 days. The blue bar is the polyaniline nanoprotrusion structure surface (PNS); the green bar is the rubbed polyaniline nanoprotrusion structure surface (RPNS); and the yellow bar is the tissue culture plate (TCP).Back to article page
