1. A process for manipulation of microscopic, dielectric particles, said process comprising the steps of:

  • exposing said particles to an electric field,suspending said particles in one of a fluid and a gel,operating said electric field to effect one or several high-frequency fields with frequencies between 0.1 MHz and 1 GHz traveling in prescribed directions, such that a traveling velocity of said high-frequency fields induces interfacial charges in said particles, which charges remain behind a traveling field vector to cause movement of said particles.
