Biosensors are logical devices composed of a recognition component of biological origin and a physicochemical transducer. Immobilization plays a leading role in developing the biosensor by integrating both the above mentioned mechanisms. In this short editorial note, an analytical review of fiber-optic sensors and biosensors for the development of biosensors for environmental and clinical monitoring have been reviewed. | ISSN:2249-5789 R Boselin Prabhu et al, International Journal of Computer Science & Communication Networks,Vol 6(5),211-216 Functionalities and Recent Real World Applications of Biosensors PRABHU Associate Professor, Department of Electronics and Communication Engineering, College of Engineering–Technical Campus, Coimbatore, India.

Biosensors are logical devices composed of a recognition component of biological origin and a physicochemical transducer. Immobilization plays a leading role in developing the biosensor by integrating both the above mentioned mechanisms. In this short editorial note, an analytical review of fiber-optic sensors and biosensors for the development of biosensors for environmental and clinical monitoring have been reviewed.
