Abstract: Law enforcement requires small, accurate and portable chemical sensing and analyzing instruments. While the electronic and spectroscopic means of measuring chemical concentrations with sensors is well developed, the function of chemical recognition still relies on fortuitous compounds that work for only a select few analytes. A systematic means for making a selective chemical recognition element would result in the availability of a wide range of chemical sensors. Immuno-reagents have been developed that can selectively recognize certain analytes, but these reagents are fragile, are made using living organisms and exhibit a limited shelf life. Molecularly imprinted polymers (MIPs) are also capable of selective chemical recognition.[1] These polymers are commonly used as the means for chemical separation and sequestering.[2] When appropriate chemical functionalities are incorporated in the polymers, molecularly imprinted polymers provide the basis of a wide range of sensors for drugs or other molecules of interest.[3-4] And, as synthetic polymers, these materials are more readily converted to form the basis for sensing since they result by design and not fortuitous circumstance
