immunosensors

Immunosensors are devices that detect specific substances, called analytes, by using immune system components like antibodies. These sensors detect the presence of targets such as bacteria, viruses, or hormones by recognizing and binding to them with high precision. When the target binds to the antibody on the sensor, it produces a measurable signal—like an electrical change—that indicates its presence and concentration. Immunosensors are used in medical diagnostics, environmental monitoring, and food safety to quickly and accurately identify substances of interest, making testing faster, more sensitive, and often portable.
