Parallel and sequential manipulation of trapping, labeling and content extraction of single cell was realized using a 2-D simple flow channels. The proposed system consists of main channels, cell trapping pockets, drain channels and single cell content collection channels. We fabricated prototypes having 16 cell trapping pockets and 512 cell trapping pockets. Sequential all single cell handling for COS-1 cell was confirmed in 16 pockets type [1]. The sequential trapping and labeling were achieved in 512 pockets type. Capture rate for COS-1 cell was 83.2% and that for BAT cell was 70.3%. These devices are useful for high throughput single cell analysis.
