Patent ID: 8350243

Claim:
An optically-induced dielectrophoresis chip, comprising: a substrate; a first electrode layer disposed on said substrate; an interface modification layer disposed on said first electrode layer; a photo-conductive layer disposed on said interface modification layer and including an optical absorbent polymeric material; a barrier layer disposed on said photo-conductive layer; a compartment forming layer disposed on said barrier layer and defining a compartment; and a second electrode layer covering said compartment forming layer, wherein said optical absorbent polymeric material is selected from the group consisting of poly (3-hexylthiophene) and [6,6]-phenyl C61 butyric acid methyl ester, wherein said interface modification layer includes an electro-conductive polymeric material selected from the group consisting of poly (3,4-ethylenedioxythiophene) and poly sodium p-styrene sulfonate, and wherein said photo-conductive layer has a thickness ranging from 300 nm to 500 nm.
