Abstract

In this work, we studied the use of light patterns with different shapes and thicknesses to manipulate dielectric microparticles with optoelectronic tweezers. It was demonstrated that the maximum velocities of the microparticles increase to a peak and then gradually decrease as the light pattern's thickness increases. Numerical simulations were run to clarify the underlying physical mechanisms and it was found that the observed phenomenon is due to the co-influence of horizontal and vertical DEP forces related to the light pattern's thickness.
