Abstract
A method and apparatus are disclosed which are directed to the use of dielectrophoresis to levitate, in three-dimensions, a neutral particle such as a biological cell. There is disclosed the use of dielectrophoresis wherein a unique combination of a particular electrode configuration and the use of an active feedback control system is utilized to obtain more precise dielectric properties of the particle.
