Highly selective molecular sensor based on dual MIP/QCM elements and a method of use thereof

摘要

A molecular sensor for detecting small concentrations of a target molecular even in the presence of other molecules having similar shape and chemistry. Two QCM sensors are provided, both of which are covered with polymeric coatings having essentially the same chemistry. One of the QCM sensors is molecularly imprinted while the other is not. The output of the two QCM signals is compared to indicate the presence of the target molecule.
