Abstracts: A brief summary of the results of interdisciplinary studies performed in Russia within bioanalytical and biomedicinal chemistry and physics for the development of methods of laboratory and clinical diagnostics ...

Synthetic phenolic compounds (pyrogallol, catechol, hydroquinone, and their derivatives bearing heterocyclic fragments) react with electrogenerated titrants, halogens, and ferricyanide(III) ions. Stoichio- metric coefficients ...

Stoichometric coefficients are found for the reactions of electrogenerated halogens and hexacyanoferrate(III) ions with natural polyphenols, namely, rutin, quercetin, and dihydroquercetin, and also with ascorbic acid. The ...

The catalytic activities of gold, palladium, and rhodium particles and their binary systems electrodeposited on the surface of a glassy-carbon electrode in the oxidation of dopamine and ascorbic acid are compared. As ...

Particles of osmium or an inorganic polymeric film of osmium oxide-ruthenium cyanide (OsO-RuCN) electrodeposited on glassy carbon (GC) electrocatalyze the oxidation of dopamine (DA), adrenaline (AD), and noradrenaline ...

The paper considers the evolution of electroanalytical methods in the former Soviet Union and Russia for more than 50 years, including the establishment of scientific research centers, the development of new methods, and ...

Estimation of the enantiomeric purity of chiral biologically active compounds, as well as the determination of particular optical isomers, is very important for the control of medicines, food, and biological fluids. The ...

The review deals with the current state of and prospects for the use of electrodes modified with noble metals, polymer films, or composites on their basis, which yield catalytic response in voltammetry. Techniques of ...

Isoquinoline derivatives (papaverine and drotaverine) are oxidized at a graphite electrode in a 0.1 M sulfuric acid solution to give voltammetric waves at 1.1 V for papaverine and at 1.05 and 1.28 V for drotaverine. ...

A new technique is proposed for detecting interactions between DNA and DNA autoimmune antibodies using a potentiometric sensor based on a glassy-carbon electrode modified with polyaniline and native DNA from chicken ...
