Biosensors are the device in which there is a coupling of biological sensing element with a detector system using a transducer. In comparison with any other currently available diagnostic device, biosensors are much higher in performance in terms of sensitivity and selectivity both. Biosensors have found potential applications in the industrial processing and monitoring, environmental pollution control, also in agricultural and food industries. Important features for commercialization of the biosensors are selectivity, sensitivity, stability, reproducibility and low cost. This article reviews the brief history, basic principles, and the various types’ of biosensors available. Keyword: Biosensors, Principle, Types and Application |
