5 Specific applications of biosensors in life and health sciences 

Biosensors are particular types of chemical sensors that specifically utilize a biological recognition element, converting biochemical signals into quantifiable electrical signals. In biosensors, the recognition element is typically an immobilized 

Most devices rely on the use of disposable one-use-only test strips , and a droplet of blood from a needle-prick is drawn, for example, from the thumb, onto the strip by capillary action. The strip represents the recognition element, and the blood sample undergoes an enzymatic chemical reaction followed by another reaction. After the blood is added to the test strip it is inserted into the hand-held device (transducer) and sufficient time allowed for the reactions to occur, most often automatically determined by the device itself.
