Electrochemical Techniques in Monitoring of Nervous System Drugs
Choińska-Mlynarczyk, Marta; Hrdlička, Vojtěch; Skopalová, J.; Šelešovská, R.; Kolivoška, Viliam; Navrátil, Tomáš
2022 - English
Drugs of the nervous system (ATC group N) belong generally to the most commonly (mis)used substances worldwide. Their determination and monitoring of these drugs and their metabolites in various body fluids or environmental matrices represent a challenge for analytical chemists. Our research is focused on the application of electrochemical methods in the monitoring of the most frequently prescribed and the newly introduced nervous system drugs of precisely specified structures and/or of defined properties. For toxicological and pharmacokinetic reasons, emphasis has been placed on investigating the reaction mechanisms of their metabolite formation. New or alternative to commonly used electroanalytical methods applicable for monitoring and characterization of target compounds in their pure state, in body fluids, wastewaters, and other environmental matrices, has been developed. To improve the chemometric parameters and sensing characteristics, attention was paid to the construction of new electrochemical sensors, detectors (e.g. screen-printed, 3D printed), or cells, based on (modified/unmodified) traditional or nontraditional materials, preferably usable at the point-of-care.

Electrochemical Characterization of Self-Assembled Monolayers Containing Redox Switching Element
Nováková Lachmanová, Štěpánka; Kocábová, Jana; Vavrek, František; Sebechlebská, Táňa; Šebera, Jakub; Kolivoška, Viliam; Lukášek, J.; Balzer, N.; Valášek, M.; Hromadová, Magdaléna
2022 - English
Adsorption properties of molecules containing [Ru(terpy)2]2+ and [Os(terpy)2]2+ redox switching element connected to the electrode surface by tripodal thiolate anchoring groups have been studied together with their charge transfer properties in the adsorbed form. STM-based current-voltage measurements confirmed that the conductance of self-assembled monolayer containing [Os(terpy)2]2+ redox switching element is lower than that containing [Ru(terpy)2]2+ element. This observation agrees with previously observed differences in the electron transfer rate constants of these molecules in their adsorbed state.

Voltammetric Determination of Psilocin and Psilocybin at Carbon-fiber PLA Electrode
Choińska-Mlynarczyk, Marta; Navrátil, Tomáš
2022 - English
Psilocin and psilocybin are two neuroactive drugs. They can be used in experimental treatment in psychiatry, moreover, also as illicit drugs to achieve hallucinations and relaxation. Easy access to these two alkaloids indicates that their monitoring in the environment and the body fluids is necessary. Electrochemistry offers fast, simple, and easy methods of their determination using laboratory-manufactured electrodes from 3D printed carbon-fiber polylactic materials. This technique of electrode fabrication can be characterized by many benefits, e.g., desired shape or diameter of the electrode, well-developed voltammetric signals, and low background currents.

Analysis of the Hydrated ions Clusters Impact on the Liquid/Liquid Interface
Mareček, Vladimír; Samec, Zdeněk; Trojánek, Antonín
2022 - English
Open circuit potential (OCP) measurements of the partition of tetrapentylammonium chloride (TPeACl) at the water/1,2-dichloroethane (DCE) interface reveal two remarkable processes. The first one is characterized by a decay of the OCP from its expected equilibrium value. This process has been ascribed to the extraction of the salt driven by its accumulation in the hydrated salt clusters in the DCE phase. The second process is characterized by the short-term potential spikes overlapping the long-term OCP records. These spikes are assumed to be associated with the collision and fusion of the hydrated salt clusters produced by the former process with the water/DCE interface.
