Food Biosensors Based on Molecularly Imprinted Polymers
This chapter provides an overview of recent progress towards the design, synthesis, and application of molecularly imprinted polymers (MIPs) as food biosensors. Molecular imprinting is an innovative approach for mimicking natural molecular recognition processes through the preparation of synthetic recognition systems. MIPs are rapidly becoming viable alternatives to natural antibodies for sensor technology. The use of MIPs as sensors for determining the presence of contaminants in food has attracted considerable interest from numerous researchers and earned these materials a special niche as analytical devices for assessing food safety. Research on MIPs is an evolving field with a wide range of applications in manufacturing, processing, analysis, and quality control of foodstuffs. MIPs have several advantages for these uses, including high sensitivity, selectivity and portability, as well as their requirement for small samples. A variety of different transducers have been developed for food sensing, including optical, electrochemical, and mass-based sensors, which are discussed in detail in this chapter.
