RECENT DEVELOPMENTS IN BIOSENSORS: AN OVERVIEW

Abstract

According to conventional definitions, a biosensor is a self-contained analytical instrument that combines a biological recognition system with a physiochemical transducer for the detection of target molecules by converting recognition signal into detectable output signal. There are a number of different types of biosensors that have been effectively used in the environment, biomedical, and food industries to find and get rid of some contaminants, whether they are living or not. The most popular sensors used nowadays include enzymatic, optical, surface plasmon resonance, DNA, phage, and bacterial sensors. The need for academics and scientists to have a solid understanding of the various types of biosensors available in these and other sectors is growing. The fundamental characteristics of biosensors, the many biological materials employed, and information on the most significant types of biosensors now used primarily in the food sector, agriculture sector, medical field and industrial sector etc.
