biosensor

A biosensor is a device that detects specific biological substances, such as chemicals or microorganisms, and converts that information into measurable signals. It typically consists of a biological component (like enzymes or antibodies) that interacts with the target substance, and a transducer that converts this interaction into an electronic or optical signal. Biosensors are commonly used in medical diagnostics, environmental monitoring, and food safety to quickly and accurately identify substances, helping to monitor health or detect contaminants. Their ability to provide real-time data makes them valuable tools across various fields.
