The size histogram and the eccentricity of A549 on the three different substrates. (a) to (c) The size histogram (area in μm2) and (d) to (f) the eccentricity, which are produced by CellProfilerxTM, of immobilized A549 cells (phalloidin-stained 532 nm) on planar glass, QNP arrays, and SiNW arrays, respectively, using laser microarray scanner (both green 532 nm and red 635 nm) after 0.5 to 45 h of incubation at 37°C. The eccentricity is defined by the ratio of the distance between the foci of the ellipse and its major axis length.
