From a more fundamental viewpoint, investigation of the mediated electrochemical responses of redox enzymes appears as an attractive means of gathering mechanistic and kinetic information on the functioning of this class of enzymes. This is, in particular, the case for studies pertaining to...

The committee notes that other research in mediated electrochemical processes has shown that the coulom-bic or electrochemical efficiency of the process is directly proportional to the concentration of the material being oxidized and rapidly decreases as the destruction approaches 100 percent—that is, as the concentration of oxidizable material becomes very small (Chiba et al., 1995). 

A full-scale design that has effectively increased cell power requirements by 50 percent to achieve the required destruction efficiencies in spite of efforts to demonstrate good electrochemical or coulombic efficiency earlier studies of mediated electrochemical oxidation (MEO) processes anticipated this outcome, noting that low coulombic...

Pd-hydroquinone-mediated electrochemical 1,4-diacetoxylation of cyclohexa-1,3-diene (118), leading to 1,4-diacetoxycyclo-hex-2-ene (119), has been investigated (Scheme 46) [156]. Palladium-catalyzed indirect electrochemical monoacetoxylation of olefins has been attained in an MeCN/Ac0H-NaC104/Ac0Na/Pd(0Ac)2-Cu(OAc)2-(C) system. The acetoxylation of cyclohexene produces unsaturated esters with less current efficiency, giving a 1 1 mixture of allylic and vinylic products [118]. 

Iron-sulfur proteins can be observed by EPR spectroscopy, either in their oxidized or in their reduced state. As a method of observing iron-sulfur clusters, EPR is discriminating but not particularly sensitive lack of a detectable EPR signal cannot be taken as evidence of absence. However, a positive EPR signal is good evidence for the intactness of an iron-sulfur cluster in a protein. Moreover, EPR can be used to follow reduction of the clusters and, by use of mediated electrochemical titrations, to estimate redox potentials. 

Some debate has also appeared concerning the charge state of adsorbed oxygen on the Pt surface, whether it is 0 , 0 , uncharged O, etc. This question arises, for example, when one tries to interpret Tafel parameters in terms of a cascade of surface-mediated electrochemical—kinetic steps. However, as already... 

MesoScale Discovery (MSD) succeeded in introducing product with a similar technology approach based upon ruthenium redox-mediated electrochemical detection (Figure 2.14). MSD is a joint venture of its parent company, MesoScale, and IGEN, a company that pioneered much of fhe work on electrochemical detechon based on the ruthenium redox system. MSD s Multi-Spot plates contain antibodies immobilized on multiple working electrode pads within each well, allowing each spot within the well to serve as an individual assay. Multiplexed cytokine immxmoassays can be performed in 96-well (4,7, or 10 spots per well) patterns with detection limits of 1 to 10 pg/mL and a linear dynamic range up to 3,000 pg/mL. Both 24-and 384-well electrode systems are available.

Mediated electrochemical sensors aside, there are few sensors involving a reaction at the sensing microzone by which the analyte is not retained to some extent during the time the analytical response is generated. Such is the case with sensors based on luminescence quenching and a few others. Although many of the reactions on which the analytical measurement rests in sensors based on acid—base reactions involve retention of protons, the sensors in question are dealt with in this Section.
