    • An apparatus providing programmable illumination pattern generation for the manipulation of colloidal particulates and biomolecules in suspension between electrodes, is disclosed. The apparatus implements LEAPS (Light-controlled electrokinetic assembly of particles near surfaces), which relies on: AC electric field-induced assembly of particles: the patterning of the electrolyte/silicon oxide/silicon interface to exert spatial control over the assembly process; and the real-time control of the assembly process via external illumination. The apparatus generates patterns of illumination and projects them onto planar surfaces. i.e., a LEAPS electrode. This enables the creation of patterns using graphical design or drawing software on a personal computer and the projection of said patterns, or sequences of patterns (“time-varying patterns”), onto the interface using a liquid crystal display (LCD) panel and an optical design which images the LCD panel onto the surface of interest, to provide for arrangements and assembly of particles in such patterns.
