Fabrication of nanofluidic devices in glass with polysilicon electrodes

In this paper we present a novel fluidic device created in glass with polysilicon electrodes. We show that it is possible to fabricate electrodes with a sheet resistance of about 400 ohm/square in the a:Si layer, used as an intermediate layer for the anodic bonding of two sodium containing glass wafers in which nanochannels have been etched. The fabricated polysilicon electrodes could be partly coated with a metal to reduce the resistance of the electrodes. Further research to use the fabricated fluidic devices on detecting and manipulating single molecules in solution is ongoing and will be reported elsewhere. (C) 2005 Elsevier B.V. All rights reserved.
