From: Highly-sensitive capture of circulating tumor cells using micro-ellipse filters
Configuration and operational diagram. (A) Diagram of Ellipse filters and configuration of single micro-elliptical pillar. Gap sizes of different arrays for micro-Ellipse filters ranging from L1 to L12 are18 µm, 16 µm, 14 µm, 12 µm, 9 µm, 9 µm, 7 µm, 7 µm, 5 µm, 5 µm, 5 µm, 5 µm, respectively. S0 to S13 are stages between two neighboring arrays. The distance between two successive arrays is 1500 µm. (B) Schematic of operating principle of CTC capture in front of Ellipse filters.
