Biosensors are potential tool for scientific developments :
For new revolution in science, it will need such tools which will able to sense, analyze and predict the process. One such tool is biosensor. Biosensor are analytical devices which are used for detections of an analyze with the help of physiochemical detector. Biosensor can be any sensitive biological element like tissue, microorganisms,organelles,biomolecules,enzymes etc. Today many biological engineers create biologically sensitive elements. Such biosensor reader are associated with electronic processor that indicates or display the results in user friendly way.
Many of such biosensors are used worldwide; one of the most common out of these is blood glucose biosensor, which uses enzymes glucose oxidase to act on substrate glucose of blood. The reaction uses electrons and reduces the FAD to FADH2. Thus is finally oxidized by electrode. The current is then measured as concentration of glucose.
Also many biosensors are being used to detect lethal gases and thus warn the end user about its leakage. Such biosensors are used in mines and other places where ventilation is the issue. Many microorganism are capable of detecting the harmful chemicals and gases even though they are present in very less amount eg in ppm (part per million). These way biosensors are most important devices when safety is the concern. Other places were these sensors are used are water treatment facilities, trace gas detection and environmental monitoring.
Optical biosensors are one of the types of it which is based on the phenomenon of surface plasmon resonance. Such techniques produce electron waves on the gold surfaces and the specific angle and wavelength of incident light is dependent on the type and surface of gold.
