Comparative studies of the electrochemical oxidation of reduced nicotinamide coenzyme (NADH) at the surfaces of chemically modified graphite paste electrodes (CMEs) are reported. Three different electroactive materials, tetracyanoquinodimethane (TCNQ), tetrathiafulvalene (TTF), and dimethyl ferrocene (dmFc), were used to construct three

To achieve effective bioprocess monitoring, sensing systems are required which are suitable for an on-line determination of substrates, inhibitors, nutrients or products. Such devices may utilise biochemical principles, i.e. the specific interaction of biochemical receptors with their surroundings. They can

Inclusion complexes of 1,1'-dimethylferrocene (DMFe) with alpha-, 2-hydroxypropyl-beta- or gamma-cyclodextrins were formed in aqueous systems. For the first time, the interacting DMFe-cyclodextrin systems have been characterized using cyclic voltammetry which enabled the estimation of the complexation order, the formation constant
This article describes the research investigations on the development of the amperometric biosensors based on mediated bioelectrochemistry. The mediated bioelectrochemistry involving horseradish peroxidase and glucose oxidase within the graphite paste is reported. The enzyme horseradish peroxidase together with electrochemical mediator
Water-soluble 2-hydroxypropyl-beta-cyclodextrin (hp-beta-CyD), a cyclic and nonreducing oligosaccharide, was used to enclose the hydrophobic guest molecules ferrocene (FeCp2) and 1,1'-dimethylferrocene (DMFeCp2) to form a water-soluble complex. At high concentrations (300 mM), hp-beta-CyD enclosed up to 100 mM FeCp2 or DMFeCp2.
