Principle of BIOSENSOR •
Biosensors are analytical tools fromed of two parts:1. Biological sensing element • It serves to selectively catalyze a reaction or facilitate a binding event. 2. Physical transducer • Converts a biochemical event in to a measurable signal.
Principle of Working • Biological Material is immobilized on some immobilization support in direct vicinity of detector. • Analyte is passed through a coloumn containig immobilized material forming products. • The products formed passes through another membrane in to the transducer. • The transducer converts products in to electric signals. • Signal processing equipment converts them in to some form of Display.
