The direct electrochemistry of cytochrome c at a gold electrode was investigated by cyclic voltammetry using, as promoters, microperoxidase (the haem-undecapeptide obtained by hydrolysis of cytochrome c), Fe(III)-protoporphyrin IX or protoporphyrin-IX, all entrapped in a cellulose triacetate membrane. The results indicate that these immobilized systems strongly enhance the rate of electron transfer between the protein in solution and the electrode surface, and thus behave as ‘solid-state’ promoters, though with differing efficiencies. These results are of interest because they raise the possibility of engineering an efficient and versatile promoter active also at inert electrode surfaces.

Anodic Behaviour

The anodic behaviour of carbamazepine (CBZ), an anticonvulsant drug, has been studied on gold electrode in 0.1 mol dm-3 phosphate buffer of pH 7.0 by using cyclic voltammetry. It has been found that the value of the oxidative current of pure CBZ at +0.90 V is a linear function of the concentration in a range from 1.0?10-7 to 1.0?10?4 mol dm?3. The detection of CBZ in the concentration of 1.0?10-8 mol dm-3 is among the lowest that have been reported for this drug using voltammetric techniques. CBZ as a content of tablet Galepsine? has been quantitatively determined. It has also been demonstrated that the modification of gold electrode with bovine serum albumin (BSA) results in a decrease of the oxidative peak current due to the binding of the drug to BSA.

Inherently Chiral

Enantioselective electroanalysis, which aims to discriminate the enantiomers of electroactive chiral probes in terms of potential difference, is a very attractive goal. To achieve this, its implementation is being studied for various "inherently chiral" selectors, either at the electrode surface or in the medium, yielding outstanding performance. In this context, the new inherently chiral monomer Naph2T4 is introduced, based on a biaromatic atropisomeric core, which is advantageously obtainable in enantiopure form without HPLC separation steps by a synthetic route hinging on enantiopure 2,2’-dibromo-1,1’-binaphthalenes. The antipodes of the new inherently chiral monomer can be easily electrooligomerized, yielding inherently chiral electrode surfaces that perform well in both cyclic voltammetry (CV) enantiodiscrimination tests with pharmaceutically interesting molecules and in magnetoelectrochemistry experiments.
