“…[45,46] It has been reported that after plasma treatment of the SPCEs, the surface roughness increases, and as a result, the water contact reduces. [47,48] The SEM results and XPS results can be corroborated with the voltammetry results. The improvement in the electrochemical activity of the SPCE in Figures 7 and 8 can be attributed to the enhanced electroactive surface area and oxidation of the electrode surface.…”

Screen-printed carbon electrode (SPCE) has various crucial applications as biosensors. The binders used in the ink formulation of the SPCEs reduce the electron transfer from an electrolyte to it. In this study, we used an argon atmospheric pressure plasma jet (APPJ), a cost-effective device, to modify the SPCE surface. Scanning electron microscopy and X-ray photoelectron spectroscopy results show binder removal and oxidation of the APPJ-treated SPCE surface. Due to binder removal and exposure of graphitic surface, the hydrophilicity of the APPJ-treated SPCE surface enhances significantly. Moreover, oxidation makes the electrode more suitable for dopamine adsorption, resulting in enhanced sensitivity. The detection limit for the APPJ-treated electrode is 1 μm, as observed in this study. Cyclic voltammetry, linear sweep voltammetry, and electrochemical impedance spectroscopy have been performed on APPJ-treated and untreated SPCEs.

This research studied the effects of argon dielectric barrier discharge (DBD) plasma on properties of chitosan film to be used as active food packaging. The effects of plasma treatment time (0, 30, 60, 90 and 120 s) on tensile strength (TS), elongation at break (EAB), colour, water vapour permeability (WVP), oxygen transmission rate (OTR), contact angle and antimicrobial activity of films were investigated. Depending on the plasma treatment time, the TS values of plasma-treated film increased, but there were no significant differences between the EAB of control and treated films. The formation of the oxygencontaining groups and the occurrence of etching affected the WVP, contact angle, roughness and antimicrobial activity of plasma-treated film. Chitosan film treated with 60 s of DBD plasma had good OTR (<0.05 cc m −2 day −1 ), hydrophilicity and antimicrobial activity against various kinds of bacteria. However, it may need longer than 60 s of the treatment time to increase the WVP of the films. Overall, these results implied that plasma treatment can be used as an alternative non-thermal approach for improving the characteristics of film packaging.

A original electrochemical sensing platform, based on screen-printed electrodes modification with plasma polymerized acrylonitrile (pp-AN) nanofilms is proposed. For that purpose, plasma-enhanced chemical vapor deposition (PECVD) process was conducted in a parallel plate (13.56 MHz) plasma reactor for 2 min with discharge power of 10 W. The surface topography and electrochemical properties of prepared sensors were investigated by X-ray photoelectron spectroscopy, scanning electron microscopy, energy dispersion spectroscopy, electrochemical impedance spectroscopy, and cyclic voltammetry. The electrochemical characteristics of pp-AN/SPCE and pp-AN/SPAuE sensors was investigated for model redox pair [Fe(CN)6]4−/3−. Conducted research confirmed the excellent chemical stability, durability, wide potential window, high signal-to-noise (S/N) ratio, and, most importantly, the ability to standardize the sensors. The pp-AN/SPCE sensor was applied to the determination of bupropion, an antidepressant drug whose intake has increased dramatically during the COVID-19 pandemic. The voltammetric response of pp-AN/SPCE for BUP was linear in two concentration ranges of 0.63–10.0 and 10.0–50.0 μmol L−1, with a detection limit of 0.21 μmol L−1. Satisfactory recoveries (96.2–102%) and good precision (RSD below 4.1%) obtained for environmental and biological samples confirmed the usefulness of the sensor for the analysis of various kinds of samples.
