Chemical sensors, biosensors and bioprobes

Todays, the strategic aim in analytical chemistry, is the simplification of the analytical methodology to a level where the measurements of the analytes in real samples become simple with a minimal operator skills. Achievement to this practical goal has resulted in construction of chemical and biochemical sensors. Because of their capability to give continuously, reversibly and selectively and also a fast response to a specific analyte in real samples without perturbing the systems, therefore, they are used in chemical industry, food and pharmaceutical industries, as well as, medicine and environmental control [1]. In this presentation, the characteristics and applications of a new optical sensor (surface plasmon resonance sensor) and some of the electrochemical sensors will be discussed.
