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.

The dramatic reduction in transmission loss of optical fibers coupled with very important developments in the area of light sources and detectors have resulted in phenomenal growth of the fiber optic industry during the last 35 years or so. Indeed, the birth of optical fiber communication systems coincided with the fabrication of low-loss optical fibers and the operation of room-temperature semiconductor lasers in 1970. Since then, scientific and technological growth in this field has been phenomenal.

Storage devices hold data, even when the computer is turned off. The physical material that actually holds data is called a storage medium. The surface of a floppy disk is a storage medium. The hardware that writes data to or reads data from a storage medium is called a storage device. A floppy disk drive is a storage device. The two primary storage technologies are magnetic and optical.
