Biosensors are integrated medical devices that provide analytical information by using the given biological samples in micro-volumes. The biosensors comprise of three major components, which include the biological recognition unit, bio elements, and transducers. The biological recognition unit interacts with the given biological samples, bio-elements, which constitutes enzymes, living tissues, antibodies, and transducers transform the signals generated from the interaction of bio-elements with biological recognition unit into an electrical signal. Biosensors are innovative/advanced-technology devices used in ultra-microanalysis, which offer high-quality output, accuracy, precision, specificity and sensitivity, within affordable prices. Thus, biosensors are considered as essential devices with the ability of quick detection and are ideal in offering low-cost, easy, quick, and portable solutions. Increasing prevalence of chronic and lifestyle-induced diseases, rising demand for POCT (point-of-care testing), growing geriatric population, and the biosensors application in nanotechnology are key drivers for the growth of this market.
