A biosensor is a device that combines a biological component with a physicochemical detector to measure the presence or concentration of chemicals, biological molecules, or pathogens in a sample. The biological element, such as enzymes, antibodies, or nucleic acids, interacts with the target analyte specifically and the interaction is converted into a measurable signal by the detector component, often producing an electrical, thermal, or optical signal. This technology is widely used in various fields including medical diagnostics, food safety, environmental monitoring, and biotechnology. Biosensors are prized for their specificity, sensitivity, and rapid response time, making them crucial in situations where quick and accurate detection is essential.
