FIG. 3.

Field and medium comparison experiments at 5 kHz and 5.5 Vpp. Columns are organized by methanol and water in uniform and nonuniform DEP electric field configurations. Rows are organized by time with t = 0, 8, and 120 s and intensity difference obtained by MATLAB image analysis. Fluorescein intensity changes are apparent in water in both uniform and non-uniform DEP electric field configurations as emphasized in (n) and (o) while negligible changes were observed in methanol in (m) and (p).
