Biosensors
A biosensor is a device for the detection of an analytic that combines a biological component with a physicochemical detector component. Many optical biosensors based on the phenomenon of surface plasmon resonance are evanescent wave techniques . The most widespread example of a commercial biosensor is the blood glucose biosensor, which uses the enzyme glucose oxidase to break blood glucose down.
Bio sensors are the combination of bio receptor and transducer. The bio receptor is a biomolecule that identifies the target whereas transducer converts the identified target into the measurable signal. Biosensors are used in the market in many diverse areas. They are also used in the clinical test in one of the biggest diagnostic market of 4000 million in US$.
They are very useful to measure the specific thing with great accuracy. Its speed can be directly measured. They are very simple. Receptors and transducer are integrated into single sensors without using reagents.
