A biosensor is a device that combines a biological component with a physical component in order to detect a target analyte. The biological component is typically an enzyme or antibody that specifically binds to the analyte, while the physical component is typically a transducer that converts the binding event into a measurable signal.
Biosensors are devices that can detect and measure the presence of a specific biomolecule. Some of the emerging trends in biosensing include the development of biosensors that can detect a wider range of biomolecules, the miniaturization of biosensors, and the development of biosensors that can be used in a point-of-care setting.
