Introduction
In early 2000, two Divisions of the International Union of Pure and Applied Chemistry (IUPAC) prepared recommendations on the definition, classification, and nomenclature related to electrochemical biosensors; these recommendations have been then extended to other types of biosensors. Following these IUPAC recommendations, “a biosensor is defined as a self-contained integrated device, which is capable of providing specific quantitative or semi-quantitative analytical information using a biological recognition element (biochemical receptor) which is retained in direct spatial contact with an electrochemical transduction element. Because of their ability to be repeatedly calibrated, a biosensor should be clearly distinguished from a bioanalytical system, which requires additional processing steps, such as reagent addition” [1].
Another important concept was introduced, some years later, by Turner and Newman in [2]; they referred to a biosensor as “a compact analytical...
