3D Printed Microfluidic Cell for Spectroelectrochemical Analysis
Šikula, M.; Vaněčková, Eva; Hromadová, Magdaléna; Kolivoška, Viliam
2023 - English
Recent advances in fused deposition modeling 3D printing (FDM 3DP) enabled \nthe manufacture of customized spectroelectrochemical (SEC) devices. Despite significant progress, \nreported designs still rely on conventional optical components (windows and cuvettes). In this \nwork, we apply bi-material FDM 3DP combining electrically conductive and optically \ntranslucent filaments to manufacture a fully integrated microfluidic SEC device. Employing cyclic \nvoltammetric measurements with redox probes, we demonstrate that the platform allows SEC sensing of \nreactants, intermediates, and products of charge transfer reactions in an oxygen- free \nenvironment. Developed approaches pave the way for SEC d vices with dramatically\nreduced costs compared to currently available commercial platforms.\n

Electrochemical Properties of Mixed Self-Assembled Monolayers Based on Terpyridine Transition Metal Complexes
Kocábová, Jana; Nováková Lachmanová, Štěpánka; Vavrek, František; Valášek, M.; Hromadová, Magdaléna
2023 - English
This work presents the electrochemical characterization of mixed self-assembled monolayers\n(SAMs) of [Os(terpy)2]2+ and terpyridine connected by tripodal anchoring groups to the\npolycrystalline gold bead electrode and provides a comparison with SAM based on\n[Os(terpy)2]2+ tripodal molecules without diluting terpyridine tripodal molecules. It is shown\nthat both arrangements enable reproducible preparation of well-defined compact films. The\nelectron transfer rate constant for mixed SAM was determined from cyclic voltammograms\naccording to Laviron’s analysis and compared with the rate constant obtained previously for\nSAM containing only [Os(terpy)2]2+ tripod.

Elimination Voltammetry with Linear Scan: Advantages and Disadvantages
Navrátil, Tomáš; Trnková, L.; Hrdlička, Vojtěch; Li, X.
2023 - English
Elimination voltammetry with linear scan (EVLS) represents an almost traditional\nmathematical method that helps to obtain additional and detailed information about the recorded\nelectrochemical signals and therefore, to better understand the analyzed systems. Although it\nhas been substantially developed and expanded during its existence of more than a quarter of a\ncentury and has found many areas of application, like any other mathematical and experimental\nmethod, it exhibits several advantages and disadvantages. In this contribution, we summarize\nits strengths, weaknesses, opportunities, as well as threats.\n

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.
