Abstract
A molecularly imprinted substrate and sensors employing the imprinted substrate for detecting the presence or absence of analytes are described. One embodiment of the invention comprises first forming a solution comprising a solvent and (a) a polymeric material capable of undergoing an addition reaction with a nitrene, (b) a crosslinking agent (c) a functionalizing monomer and (d) an imprinting molecule. A silicon wafer is spincoated with the solution. The solvent is evaporated to form a film on the silicon wafer. The film is exposed to an energy source to crosslink the substrate, and the imprinting molecule is then extracted from the film. The invention can be used to detect an analyte by forming films which are then exposed to a reaction energy to form a crosslinked substrate. The imprinting molecules are extracted from the crosslinked substrate. The film is exposed to one or more of the imprinting molecules for a period of time sufficient to couple the imprinting molecules to the film. The presence of the molecules is then detected. The invention also provides a molecularly imprinted polymeric material and sensors employing the molecularly imprinted polymeric material.
