Microfluidic experiments with washed platelets. Optical images of (A) PMMA2 and (B) PMMA4 coated chips during the flow experiments performed with washed platelets (WP). The images were taken when (1) 20 μL and (2) 80 μL of WP solution had passed through the channels and (3) after chip rinsing. The arrows indicate the flow direction. (C) Statistical distribution of adhered platelets onto the chips having different surface topographies according to Table 1 after rinsing. Each bar represents the average number of platelets counted over 20 SEM images having the same surface area.
