Design of Optochemical Sensors

The fundamental operation of an optochemical sensor consists of three main steps the analyte-recognizing element interaction by means of any of the different mechanisms that are schematized in Fig. 1 [3] the detection and transduction of any physical or chemical variation caused by the recognizing reactions and the signal processing and the acquisition of results. 

Concerning the required instrumentation, usually conventional active and passive optical components are employed however, their complexity can vary according to the proposed objectives. Two main parts can be distinguished the recognition element, which includes the selective reagents, the intermedi-
