In the publication “Low frequency cyclical potentials for fine tuning insulator-based dielectrophoretic separations,”1 Table I had the zeta potential, EK mobility, and DEP mobility for particle 1 listed under particle 2 and vice versa. A corrected table is shown below.
TABLE I.
List of particles used for this study with the associated particle properties. The particle zeta potential, EK mobility, and DEP mobility were found experimentally. Reported uncertainties for ζparticle and μEK are one standard deviation. Reported uncertainties for μDEP are based on the accuracy of the image based determination of trapping distance and the uncertainty of μEK.
