Abstract
The electrical characterization of a biohybrid integrated circuit is d escribed. Uromyces appendiculatus is the biological moiety and an inte grated circuit provides the electrical interface between the biologica l element and the test equipment. Direct current characterization has shown the current flow to be nonlinear with a time constant of 30-60 s . The conductivity is believed to be ionic through intracellular ions of the fungal cell. Locations of the germ tube which have different io n compositions have shown contrasting responses to testing over time. Potential applications are reviewed. (C) 1997 American Vacuum Society.
