Figure 5.

Trapping behavior for three serovars (identification noted above each plot) at various applied potentials (V_A). All data was collected at a 27 µm gate in the V1 microchannel after the potential was applied for 10 seconds (t_A). Slope was assessed using signals exceeding the background limit (twice the standard deviation of the baseline data points). Dotted red lines are fitted from the linear part of the data (see text) above the baseline and background limit. The initial trapping voltage is determined by the x-intercept of the linear fit line. The error bars are the 95% confidence interval. Using the linear fits, both the electrokinetic and dielectrophoretic mobilities can be determined using the voltage based physical model (see text).
