Paper Abstract

A monolayer of antibody on a semimirror comprised of small islands of indium acts as a sensor capable of detecting vapors at extremely low concentrations without the use of wet chemistry. Already shown capable of detecting cocaine vapors at 4 femtograms per cc of air, the use of the device, called an immunoassay film badge, for detecting drugs on the breath is a natural extension of the sensor's use. This paper describes this application and initial experiments that demonstrate its feasibility.
