means a device that uses a biological detector, like an enzyme or antibody, to spot a specific substance and convert that detection into a measurable signal.
from the concept traces to 1956, when leland clark built an electrode that measured oxygen using an enzyme, later called the father of biosensors after his glucose enzyme electrode in 1962.
