Abstract
A quartz crystal microbalance assay in which the binding of analyte to a surface on or near a quartz crystal microbalance (QCM) is detected by a conjugate which comprises an enzyme capable of catalyzing the conversion of a substrate to a product capable of accummulating on or reacting with a surface of the QCM leading to a mass change and, hence, a change in resonant frequency.
