Optical Biosensors

An optical biosensor is a compact analytical device containing a biorecognition sensing element integrated with an optical transducer system. biosensors have been proposed for a range of application and, aiming clinical analysis application, the amperometrical, potentiometrical and optical are the biosensors which have achieved most significant development. In concept, optical biosensors are those based on the detection of changes on absorption of UV/visible/Infrared light when chemical reactions occur or on the quantity of light emitted by some luminescent process. Regarding to supramolecular nanostructures and their ability of enhancing the sensing activity when applied to biosensors
