Amperometric biosensors are analytical devices that measure the current produced by the electrochemical oxidation or reduction of an analyte in a sample, providing information about the concentration of that substance. These biosensors typically consist of a biological recognition element, such as an enzyme or antibody, coupled with an electrochemical transducer that converts the biological interaction into an electrical signal. This connection allows for real-time monitoring and analysis of various biochemical substances, making amperometric biosensors particularly valuable in clinical diagnostics and environmental monitoring.
