Patent ID: 7014742

Claim:
An apparatus for moving a micrometer size object having a first dielectric permittivity comprising: a micro-well including a substrate, electrodes on the substrate in position to produce an electrical field in the micro-well, a dielectric fluid located on the substate, comprising a dielectric permittivity different from the first dielectric permittivity; and a source of electricity to the electrodes to produce the electrical field in the micro-well, wherein the a micrometer size object within the micro-well is configured to move by electrophoresis or dielectrophoresis, wherein the micro-well comprises an electrophoretic micro-well or a dielectrophoretic micro-well, wherein the micrometer size object comprises a microlens; and an optical light beam aligner to align the microlens with an optical light beam, wherein the optical light beam comprises a laser light beam.
