Chapter 4 Immunochemical and Receptor Technologies: The Role of Immunoassay, Immunoaffinity Chromatography, Immunosensors and Molecularly Imprinted Polymeric Sensors

摘要: Publisher Summary This chapter discusses the most representative immunochemical technologies applied to food analyses. Immunoassays are for measurement of both single and multiple analytes. Chemical pesticides, polychlorinated biphenyls (PCBs), antibiotics typical examples contaminants that can be rapidly efficiently determined by antibody-based methods. Antibodies enable a rapid detection analyte in water, body fluids, soil, or extracts, they also exploited sample preparation prior detection. offer number advantages contaminant analysis over conventional methods—such as liquid-chromatography (LC)- gas-chromatography-based methods—because immunoassays provide fast, simple, cost-effective detection, with sensitivity cases comparable better than techniques. In addition, possible automation versatility applications techniques have made these more popular recent years. Immunosensors specific case biosensors, constitute advanced based on binding properties antibodies. The highlights development molecularly imprinted polymers (MIP). MIPs recognition elements been successfully analytical chemistry an alternative immunoaffinity systems; affinity chromatography, assays, sensor developments.
