Abstract
A method of photoelectro-manipulation of target molecules including providing a photoconductive layer of material having a first and a second electrically conductive contact on a first surface thereof and a probe on an opposed second surface. A solution containing target molecules is positioned in electrical contact with the probe. A positive potential is connected between the solution and the first electrically conductive contact and a negative potential is connected between the solution and the second electrically conductive contact. A beam of light is directed through a portion of the photoconductive layer of material to complete an electrical circuit between one of the first and the second electrically conductive contacts and the solution, whereby target molecules in the solution are attracted to or repelled from the probe which is coupled into the electrical circuit by the beam of light.
