However, it should be mentioned that there is a flexible hand-held electrochemical instrument on the market, which can be programmed to be used in a variety of voltammetric/amperometric modes in the field [209]. Although the majority of biosensor applications described in this review were for single analyte detection, it is very likely that future directions will involve development of biosensor arrays for multi-analyte determinations. One example of this approach has been described in an earlier section, where five OPs could be monitored with an array of biosensors based on mutant forms of AChE from D. melanogaster [187]. This array has considerable potential for monitoring the quality of food, such as wheat and fruit. Developments and applications of biosensors in the area of food analysis are expected to grow as consumer demand for improved quality and safety increases. Another area where biosensor developments are likely to increase significantly is in the field of environmental analysis, particularly with respect to the defence of public... 

In this section, the results corresponding to an EE process are generalized for a multi-electron electrochemical reaction of k steps (multi-E process) in agreement with the reaction scheme ... 

In this section, the general analytical expression for the current-potential response (Eq. (6.15)) is particularized for the electrochemical techniques Cyclic Staircase Voltammetry (CSCV) and Cyclic Voltammetry (CV). Thus, the expression for the CSCV and CV currents of multi-electron processes at electrodes of any geometry and size is... 

Kinetic measurements with bipolar electrochemical cells were made using the same experimental setup as with single-pellet cells described in Section III.2.H and seen in Figure 7. Two types of bipolar electrochemical cells have been developed in our laboratory, a ring-shaped and a multi-channel configuration. As shown in Figure 28,... 

AC conductance is noninvasive, quick and the test instruments are relatively inexpensive. There are, however, some fundamental problems. Most commercial testers use only one frequency, which is commonly below 100 Hz. Multi-frequency systems would be more accurate but require complex data interpretation software and expensive hardware. In this section we focus on electrochemical impedance spectroscopy (EIS), a method that overcomes some of the shortcomings of AC conductance. 

Let us consider in detad the arrangement of the electrochemical reactor with a functional multi-layer electrode and the properties of each functional layer. The cross-section view of the functional multi-layer electrode is shown in Fig.6.
