Electrochemical biosensors

Electrochemical biosensors are devices that detect specific biological molecules by converting a biological response into an electrical signal. They use a biological element, like an enzyme or antibody, to recognize the target substance, and a transistor or electrode to produce a measurable electrical change. These sensors are precise, quick, and sensitive, making them useful for medical diagnostics, environmental monitoring, and food safety. Essentially, they turn biological information into an electrical readout that can be easily measured and interpreted.
