ABSTRACT

Biosensors are analyzers used to detect chemicals in combination with physicochemical detectors. It is a combination of a biological sensing element and a transducer, which converts the data into electrical signals. Additionally, there will be an electronic circuit which consists of a signal conditioning unit, a processor or microcontroller and a display unit. Various biosensors ranging from nanomaterials, polymers to microbes have wider potential applications. Integrated approaches provided a better perspective for developing specific and sensitive biosensors with high regenerative potentials. Biosensors have been applied in many fields namely food industry, medical field, marine sector etc., and they provide better stability and sensitivity as compared with the traditional methods. Biosensors can provide cost-effective, easy-to-use, sensitive and highly accurate detection devices in a variety of research and commercial applications.
