Fig. 4. Microscopy images of PI-stained trapped versus nontrapped E. coli at high frequency (5 MHz), various applied voltages, and operation times.

Fig. 4

PI uptake (red fluorescence) indicates cell electroporation. (A) Trapped and (B) untrapped E. coli are shown. (C) Percentage of both trapped and untrapped PI-stained E. coli at various applied voltages (5 MHz). Error bars represent SD computed from three independent tests. JP of 10 μm in diameter was used. Scale bars, 5 μm. E. coli strain XL1-Blue bacteria with GFP labeling were used.
