The method of electrochemical pretreatment of platinum electrode with the goal of standardizing the initial state of electrode surface and its open-circuit potential (OCP) in the blood and other biological media is proposed. The platinum electrode potential is measured in 0.14 M Na 2SO4 aqueous solution, in the blood and blood plasma and serum. By the examples of OCP measured in the blood serum of patients with acute poisoning, acute cerebral pathology and patients treated by the method of hyperbaric oxygenation, it was found that the values of blood serum OCP were different for studied pathological states and healthy people. © Pleiades Publishing, Ltd., 2010.

A method to determine antioxidant activity of blood plasma using glassy carbon modified with cobalt hexacyanoferrate has been developed. Linear dependence of the current on the antioxidant concentration was obtained within the range 2.5 × 10−4–2.5 × 10−1 g/L. It has been shown that the values of antioxidant activity of blood plasma samples of apparently healthy volunteers are in agreement with literature data. © 2015, Pleiades Publishing, Ltd. Source

Dependences of the platinum-electrode potential in an open circuit on time in blood serum are analyzed, and coefficients of the equation describing these dependences are obtained. A difference in the values of equation coefficients is observed upon favorable patient recovery after kidney transplantation and transplant dysfunction. © 2014 Pleiades Publishing, Ltd. Source

A method of production of hemosorbent based on thermally expanded graphite is developed. The method involves the electropolymerization of pyrrole on rolled thermally expanded graphite and subsequent cyclic electrochemical doping of polypyrrole film with Cl- anions. The method enables one to produce a hemosorbent with an open-circuit potential, which is necessary for its biocompatibility. © 2013 Pleiades Publishing, Ltd. Source

Activated carbons and thermally expanded graphite were modified by pyrrole electropolymerization. Both positive and negative shifts of open circuit potential were observed, depending on the initial potential of the carbon material. Pyrrole electropolymerization on carbon material also occurred when carbon was pre-modified to a potential more positive than +600 mV (vs. Ag/AgCl). ©The Electrochemical Society. Source
