Molecularly Imprinted Polymers

Physical and Analytical Chemistry Seminar

Location: Faculty Seminar Room

Abstract:

The field of molecular imprinting in synthetic polymers is one of the most exciting areas in chemistry and material science today.  The imprinting of polymers on the molecular level may be described as the formation of sites or cavities within the polymer that are receptive to a specific molecule or group of related molecules. The formation of these cavities is achieved by the synthesis of the polymer in the presence of a specific molecule. The molecule around which the polymer is synthesized, is known as the template and the subsequent removal of the template, after polymer formation, results in the creation of the selective sites. These sites are then available for rebinding of the target molecule based on shape, size and most importantly, functionality, all combining to promote a high degree of molecular recognition. The polymer thus formed is known as a molecularly imprinted polymer (MIP).

The high degree of selectivity and specifity reported for MIPs, coupled with their inherent robustness and stability, make them attractive for use in a wide range of applications.
