Abstract
In this research, deposition pattern of tin oxide nanoparticles in acetone media under non-uniform AC electric fields on planar gold electrodes have been studied. Particle size is one of the basic parameters affecting the electrokinetic behavior of particles under applied electric fields. Based on deposition pattern observations, micron size particles were deposited on electrode surface at frequency of 10 kHz. In this study, Clausius- Mossotti factor was depicted for different particle sizes. It indicates that for coarse particles dielectrophoretic force is negative and for fine particles dielectrophoretic force is positive.
