(a) Capturing efficiency vs length ratio (LB∕LA) when a channel width ratio (WB∕WA) is 2.5 (error bar represents its standard deviation, N=8). (b) Photograph of captured single green-fluorescence-activated PC3 cells in microwell array. Only one PC3 cell was captured at each capturing site. In the image, 39 microwells are occupied with single cells out of 42 microwells, (d) and (e) Single cell culture for three days: photographs were taken in an identical microwell at day 0 (c) and day 3 (d).
