Working principle of the SCM‐Chip. a) Photograph of SCM‐Chip indicating the inlet. Scale bar: 15 mm (Region 1), one of the three multi‐microchannel branches (Region 2), and different isolated outlets (Region 3). b) SEM of the chip with higher magnification of microchannel and magnified hooks for single‐cell capture. Scale bars: 500 and 50 µm. c) Work flow for single‐cell mobility array using SCM‐Chip, including single‐cell capture, cell washing, single‐cell migration, and specific cell recovery. d) Characterization of MDA‐MB‐231 cell loading (I), scale bar, 200 µm, single‐cell migration (II), and functional retrieval on‐chip (III).
