Abstract
Electrochemical impedimetric biosensors (EIBs) have a simple structure and can be used to rapidly and sensitively detect and measure hazards in food. EIBs detect and measure target molecules by transducing biochemical reactions on their surface to electrical signal outputs responding to a sinusoidal electrical signal input. Due to their structural simplicity and analytical sensitivity, EIBs are regarded as the most potent method of food hazard monitoring that can be implemented in the food supply chain. This paper discusses the theoretical background, structure, and construction of EIB and its applications in food safety.

Electrolyte resistance (Rs), double-layer capacitance (Cdl), and charge-transfer resistance (Rct) at the electrode/electrolyte interface may be involved in the alteration of Z on application of a sample to EIBs
