ABSTRACT:
A biochemical analyte sensor comprises a pair of electrical conductors in a fluid environment. Between the conductors is a surface of silicone rubber, for instance. An enzyme/substrate combination causes molecules of a volatile material to be produced in the fluid. The volatile material nucleates as bubbles near the surface of the sensor. The bubbles displace molecules of the fluid from the surface and drastically alter the dielectric properties on or near the sensor surface.
