Device Characterization.
(A) Comparing SOI (Silicone-On-Insulator) vs. Non-SOI wafer fabrication and the resultant leakage-proof performance. Scale bar 50 μm (B) Characterization of cell uniformity distribution in the channels by injecting L929 fibroblasts. Each channel was divided to four zones (A–D) which were indexed based on the directionality of the flow. Scale bar, 200 μm (C) (a) Boxplot of the normalized cell number in each of the zones for the injected bulk cell concentrations of 106 cells/ml, 2 × 106 cells/ml and 4 × 106 cells/ml (b) Linear curve fit between average number of cells in each zone and the inoculum concentration (cell suspension concentration).
