Fig. 9.

(a) Continuous flow rates at 1, 4, 7 and 10 μL/min at room temperature while keeping time constant at 2 min period. The concentration of target DNA is 50 pM and the height of microfluidic flow channel is 50 μm. Fluorescence signals in the first row correspond to 10 μL/min, 7 μL/min in the second row, 4 μL/min in the third row and 1 μL/min in last row. Note that there is no indication of binding at the Corona Virus DNA sites, the control or inside the ellipses. (b) Fluorescence intensity vs. continuous flow at different heights for 2 min. Flow rate of continuous flow were 1, 4, 7 and 10 μL/min. The concentration of target DNA was 50 pM. The number of experiments done (n) is equal to 6.
