10. The electrochemical response to Au electrode modification steps towards viral electrochemical immunosensor preparation

Author

Białobrzeska, Wioleta, Brodowski, Mateusz, Kowalski, Marcin, Bogdanowicz, Robert, and Ryl, Jacek

Subjects
electrochemical immunosensor, gold electrode, electrode functionalization
Abstract

The dataset contains the electrochemical measurements (CV/EIS) carried out for the consecutive steps of the Au electrode functionalization, in separate subfolders, as described. The cyclic voltammetry (CV) was conducted using a Palmsens 4 potentiostat/galvanostat system (Methrom, Autolab, Netherlands) in the standard three-electrode configuration, with the Pt mesh was used as a counter electrode, and Ag/AgCl/0.1M KCl as a reference electrode. In the case of the EIS, the frequency ranged from 10 kHz to 0.2 Hz for Au electrode with 40 points. The amplitude of the alternating current (AC) signal was 10 mV. Each potential was held constant for 5 s before each measurement to obtain steady-state conditions. All electrochemical tests were carried out in 5 mM K3[Fe(CN)6]/K4[Fe(CN)6]/in 0.01 M PBS that was previously deaerated. The voltammetric behavior of the modified gold electrode in the presence of a simple redox system, K4[Fe(CN)6] in the supporting electrolyte of 0.1 M KCl, was compared with that of the bare electrode.

Subjects
SARS-CoV-2, XPS, electrochemical sensor
Abstract

This dataset contains the results of the high-resolution XPS analyses of a set of boron-doped diamond (BDD) electrodes after consecutive functionalization steps toward anchoring of a receptor capable of SARS-CoV-2 virus detection. The analysis was carried out in the binding energy range of C1s, N1s, O1s, Ni2p3/2. The measurements were carried out on Escalab 250Xi spectroscope (Thermofisher Scientific). The dataset requires the use of Avantage software to work (ThermoFisher Scientific).

26. Corrosion Inhibition Mechanism and Efficiency Differentiation of Dihydroxybenzene Isomers Towards Aluminum Alloy 5754 in Alkaline Media.

Abstract

The selection of efficient corrosion inhibitors requires detailed knowledge regarding the interaction mechanism, which depends on the type and amount of functional groups within the inhibitor molecule. The position of functional groups between different isomers is often overlooked, but is no less important, since factors like steric hinderance may significantly affect the adsorption mechanism. In this study, we have presented how different dihydroxybenzene isomers interact with aluminum alloy 5754 surface, reducing its corrosion rate in bicarbonate buffer (pH = 11). We show that the highest inhibition efficiency among tested compounds belongs to catechol at 10 mM concentration, although the differences were moderate. Utilization of novel impedance approach to adsorption isotherm determination made it possible to confirm that while resorcinol chemisorbs on aluminum surface, catechol and quinol follows the ligand exchange model of adsorption. Unlike catechol and quinol, the protection mechanism of resorcinol is bound to interaction with insoluble aluminum corrosion products layer and was only found efficient at concentration of 100 mM (98.7%). The aforementioned studies were confirmed with Scanning Electron Microscopy and X-ray Photoelectron Spectroscopy analyses. There is a significant increase in the corrosion resistance offered by catechol at 10 mM after 24 h exposure in electrolyte: from 63 to 98%, with only negligible changes in inhibitor efficiency observed for resorcinol at the same time. However, in the case of resorcinol a change in electrolyte color was observed. We have revealed that the differentiating factor is the keto-enol tautomerism. The Nuclear Magnetic Resonance (NMR) studies of resorcinol indicate the keto form in structure in presence of NaOH, while the chemical structure of catechol does not change significantly in alkaline environment.
