Abstract
A composition is provided which is a transducing polymer having from 1 to 20 crosslinks per polymer molecule and selected from the group consisting of amphoteric co- or ter-polymers of pI between 6.2 to 8.0 of acrylic acid, alkyl methacrylate, and N,N-dimethly-aminoethyl methacrylate, the amphoteric co- or ter-polymer immobilized on a surface. Also provided is a method for the preparation of an analyte-responsive polymer immobilized on a surface in which the steps are a. mixing a solution of a crosslinker and the claimed transducing polymer, b. applying the solution of step a to a surface, and c. then curing the polymer to a ratio of from 1 to 20 crosslinks per transducing polymer molecule. Acoustic and optical methods for detecting analtyes are also provided which use an analyte-responsive polymer.
