Fig. 5. Representative microscopic photographs of cell samples collected from (a) input inlet of inertial sorting device, (b) target outlet of inertial sorting device, and (c) target outlet of acoustic sorting device. A representative cancer cell in each sample is indicated by a blue dashed circle. Scale bar is 100 μm. (d) Experiments 1–3 refer to the three repeated experiments under the same sorting conditions. Purity 1 and viability 1 refer to the purity and viability of cancer cells from sample (a). Purity 2 and viability 2 refer to the purity and viability of cancer cells from sample (b). Purity 3 and viability 3 refer to the purity and viability of cancer cells from sample (c). (e) and (f) show proliferation of cancer cells collected from the final sorting output.
