Figure 3: Creating Concentration Gradients with the PDMS SlipChip.

Caption

(a) Visualization of a stepwise concentration gradient: Fluorescence microscopy images show Rhodamine 6G dye distributed across microwells (#1-6) in the optimized PDMS SlipChip. (Scale bar: 1 mm). (b) Quantitative confirmation: A bar graph shows the measured fluorescence intensity in each corresponding microwell, verifying the controlled generation of the gradient.
