Proteins residual test on MDC. a Fluorescence image of the surface of MDC after transporting protein droplets several times. Inset numbers are CP. b The dependence of CP and related times of usage. c Fluorescence image of PDMS chip (control experiment) after transporting protein droplets 1 time. Instant test shows the presence of proteins on such a PDMS chip. Even after water rinsing, 96% of protein residuals can be detected. Ultrasonic cleaning can remove most of the protein residuals, while the CP is still much larger than that of MDC used for 1000 times. The scale bar is 200 μm
