Abstract:	Ion channels are proteins that act as pores in cell membranes and allow only specific ions to pass through the cell wall. Here, we present a method for microfabrication of apertures in a silicon substrate using well-known cleanroom technologies. Apertures were etched through a silicon wafer using a plasma-etcher and then rendered hydrophobic with chemical vapor deposition of a Teflon surface layer. Characteristic measurements showing physiological single channel gating behavior of OmpF porin and alpha-hemolysin channel proteins have been made.
