Fig. 3From: An integrated microfluidics platform with high-throughput single-cell cloning array and concentration gradient generator for efficient cancer drug effect screeningCharacterization of concentration gradient generation on MAC with fluorescein sodium (green) and sulforhodamine B (red). a Representative area of the 6 channels showing the fluorescence distribution with single-cell derived clones (stained as Hoechst 33342) in the microchambers. Scale bar = 400 μm. b Normalized intensity of fluorescein under different flow rates in the 6 channels. c Normalized intensity of fluorescein at different time points under 0.05 μl/min in the 6 channelsBack to article page
