Numerous biosensors have been fabricated to detect chemical contaminants, such as pesticides, in food. A biosensor is the preferred rapid, in-field, portable, and low-cost detection method. An enzymatic biosensor includes (1) an enzyme immobilized to catalyze reactions, (2) a transducer to convert and transfer the variations in the reaction, and (3) output that can be read and analyzed. The substrate, enzyme, incubation time, and immobilization type are important factors that can affect the performance of enzymatic biosensors. The objective of this chapter is to provide a comprehensive description of biosensors and factors that affect their efficacy in detecting pesticides in foods.
