  • Publication number: 20070105239
    Abstract: A method for forming vertical electrodes in a microchannel includes providing a substrate having a cross-linked polymer layer thereon. A plurality of electrical contacts are then patterned on the cross-linked polymer. A photoresist is applied on the cross-linked polymer overtop the electrical contacts. Holes or vias are formed in the photoresist and a metallic material is deposited therein to form vertically-oriented electrodes. Optionally, the electrodes may be coated with a biocompatible metal such as platinum. The remaining photoresist on the cross-linked polymer is then removed. An epoxy-based photoresist such as SU-8 is applied over the substrate and portions of the photoresist are lithographically exposed and removed to form the microchannel. The vertical electrodes may be located on opposing sides of the microchannel. Finally, the microchannel is sealed a cap.
