Figure Lengend Snippet: 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).

Article Snippet: The respective rows from top to bottom are: first row shows 2-D gray scale image averaged pixel by pixel from 5 experimental repeats (a)–(d), the second row is a 3-D mesh image where the z height corresponds to the intensity magnitude (e)–(h), and the third row is a 3-D mesh of the pixel by pixel standard deviation calculated from the 5 experiments (i)–(l). fig ft0 fig mode=article f1 fig/graphic|fig/alternatives/graphic mode="anchored" m1 Open in a separate window FIG. 4. caption a7 (a)–(d) Gray-scale 2-D dye intensity plot at t = 0, 8, 80, and 120 s under 5.5 V pp and 5 kHz. (e)–(h) 3-D MATLAB plot of the same data at the same time points. (i)–(l) Calculated standard deviations of 5 repeats of the data in the first two rows. (m) Diagram illustrating regions examined for intensity analysis. (n) Time dependencies of the regions in (m).
