Figure 6

Size distribution and enlarged SEM images of A549 cells. (a) Cell size and (b) nucleus size distribution (in μm2) of immobilized A549 cells on STR-functionalized three different substrates (planar glasses, QNP arrays, and SiNW arrays) after 0.5 to 45 h of incubation. (c) to (e) Top, tilled, and enlarged SEM images of A549 cells bound on SiNW arrays after 21 h of incubation at 37°C. The SiNW substrate was bent toward the center of the cells due to the high traction force these cells exerted (see arrows which indicate the bending direction).
