Voltammetric Study of the Total Activity of Antioxidants in the Blood Serum of Patients with Neurological Diseases

Abstract

One of the main directions in the development of modern electroanalytical chemistry is the development of new effective methods for research and analysis of biological objects, particularly, human blood serum. The creation of new electrochemical sensors is a promising approach, which has determined several main directions in applied voltammetry in the field of chemical analytical control. In this work, the dynamics and parameters of total antioxidant activity of human serum blood of patients with chronic cerebral ischemia, during treatment with pharmaceutical drugs Mexidol, Cavinton Comfort, and Cytoflavin was tested by cathode voltammetry with a model process of oxygen electroreduction, using a new electrochemical sensor.

Electrochemical Deposition of Aggregated Cobalt Sulfophthalocyanines at Gold Surfaces in Alkaline Solutions

“…There are a number of scientific papers in the literature on electrochemistry and electrocatalysis involving dmetal phthalocyanines. [22][23][24][25][26][27][28][29][30][31][32][33][34][35] However, they are often contradictory and limited in the number of objects of study. The lack of systematic data on the effect of the structural and functional modification of metal phthalocyanine compounds on their electrochemical and electrocatalytic properties creates great difficulties in understanding the kinetics and mechanism of electrochemical processes occurring on the electrodes of chemical current sources, as well as in carrying out a targeted synthesis of complexes with predetermined properties.…”
