Abstract

This paper describes the detection of Vesicular Stomatitis Virus using a novel capacitive immunosensor technology, whereby the respective antibodies for the antigens were used as a means for chemical detection on separate sensors. Devices were fabricated using standard etching and metal plating techniques, followed by immobilization of antibodies. Detection of antigen was performed by measuring voltage change due to changes in capacitance as antigen bound to the antibody surface. Capacitance changes were detected upon binding of specific antigen to the surface. This rugged, prototype device detected VSV down to the 2 pg/ml range.
