Electrochemical Sensors Based on Molecularly Imprinted Polymers

Abstract

Over the past two decades, molecularly imprinted polymers (MIPs) have attracted broad interest from scientists engaged in sensor development. This attention can be explained by the serious potential advantages of using MIPs in place of natural receptors and enzymes such as their superior stability, low cost and easy preparation. This review encompasses recent achievements in molecular imprinting related to the area of sensor technology. Since electrochemical biosensors dominate the market and due to specific requirements of this journal, the emphasis of this review will be on the development of electrochemical MIP sensors. The problems associated with application of imprinted polymers in sensors are highlighted and possible solutions indicated. The commercial potential of MIP-based sensors is analyzed in the expectation that they can offer improved performance in the analytical market place.
