An attempt was made to arrange polystyrene latex particles (2, 5, and 10 
m in diameter) dispersedin aqueous media making use of their dielectrophoresis and electrophoresis with a hyperbolic quadrupleelectrode system. Application of a high-frequency ac field enabled the particles to arrange themselvesbetween the electrodes forming a particle monolayer due to the negative dielectrophoretic force. Simultaneousapplication of high-frequency ac and dc fields caused the particles to gather in the region surrounded bythe electrodes to form particle multilayers. Appropriate choice of the way of applying an electric field thusallowed the reversible control of particle arrangements (monolayer, multilayer, dispersion). Reapplicationof an ac field to the particle layers produced highly dense particle multilayers.
