Washing data for flat and micropillar channels. The treated flat and microchannel samples were coated with streptavidin. (a) Integrated intensity of supernatant after first wash with 75 μL of DI water through channel. (b) Comparison of integrated intensity of the supernatant after washing 75 μL of DI water through the channel the first and second time. Inset shows the uncorrected emission curve of washed reporter probe for the treated micropillar channel. (c) Integrated intensity of reporter probes released with UV light exposure. Error bars are standard deviation of the mean.
