ABSTRACT:
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, patterning of an electrolyte/silicon oxide/silicon interface to exert spatial control over the assembly process, and real-time control of assembly via external illumination. The apparatus generates patterns of illumination and projects them onto planar surfaces, i.e., LEAPS electrodes. 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 that images the LCD panel onto the surface of interest to provide for the assembly of particles within such patterns.
