Antioxidants are widely found or used in food, pharmaceutical, and cosmetics industries; thus, rapid and sensitive detection of antioxidants is of great interest. The present work reports a simple and fast electrochemical method for direct analysis of antioxidants in fruit juices by modulating the permeability of mesochannels on the electrode surface. This goal was achieved by growing vertical silica mesochannel array (SMA) with a channel diameter of 2-3 nm on the indium tin oxide (ITO) electrode surface using the cylindrical micelles (CMs) as the template. As-prepared electrodes, designed as CM@SMA/ITO, are only permeable to lipophilic antioxidants, e.g., retinol, with the hydrophobic hydrocarbon cores of CMs. After excluding CMs from silica mesochannels, the ITO electrode modified with bare SMA, namely SMA/ITO, possesses a high density of silanol groups on the channel wall and thus is only permeable to hydrophilic antioxidants, such as ascorbic acid (AA). Two types of sensors allowed the selective analyses of retinol and AA in buffer solutions and demonstrated a wide linear range for retinol (1-60 muM) and AA (10-2000 muM), respectively, and a low detection limit (0.65 muM for retinol and 0.52 muM for AA). Moreover, the SMA/ITO electrode can selectively determine the concentration of AA in orange juice. The CM@SMA/ITO electrode can measure the sum activity of lipophilic antioxidants, such as retinol, alpha-tocopherol, and others possibly coexisting, in carrot juice. In addition, the ultrasmall mesochannels and CMs could effectively exclude the access of large substances, rendering an excellent antifouling and anti-interference ability for direct analysis of antioxidants in fruit juices without sample pretreatment.

Aims: H2O2 is produced by all eukaryotic cells under physiological and pathological conditions. Due to its enormous relevance for cell signaling at low concentrations and antipathogenic function at high concentrations, precise quantification of extracellular local hydrogen peroxide concentrations ([H2O2]) originating from single cells is required. Results: Using a scanning electrochemical microscope and bare platinum disk ultramicroelectrodes, we established sensitive long-term measurements of extracellular [H2O2] kinetics originating from single primary human monocytes (MCs) ex vivo. For the electrochemical techniques square wave voltammetry, cyclic and linear scan voltammetry, and chronoamperometry, detection limits for [H2O2] were determined to be 5, 50, and 500 nM, respectively. Following phorbol ester stimulation, local [H2O2] 5-8 mum above a single MC increased by 3.4 nM/s within the first 10 min before reaching a plateau. After extracellular addition of H2O2 to an unstimulated MC, the local [H2O2] decreased on average by 4.2 nM/s due to degradation processes of the cell. Using the scanning mode of the setup, we found that H2O2 is evenly distributed around the producing cell and can still be detected up to 30 mum away from the cell. The electrochemical single-cell measurements were validated in MC populations using electron spin resonance spectroscopy and the Amplex UltraRed assay. Innovation and Conclusion: We demonstrate a highly sensitive, spatially, and temporally resolved electrochemical approach to monitor dynamics of production and degradation processes for H2O2 separately. Local extracellular [H2O2] kinetics originating from single cells is quantified in real time.

In the present manuscript, the electrochemical behavior of cytochrome c (cyt-c) immobilized onto a phenolic terminated self assembled monolayer (SAM) on a gold electrode is investigated using cyclic voltammetry (CV) and scanning electrochemical microscopy (SECM). The tunneling electron transfer (ET) rate constant between the immobilized protein and the underlying electrode surface, and also the bimolecular ET rate constant between the immobilized protein and a probe has been obtained using approach curves that were obtained by SECM. The approach curves were recorded at different substrate overpotentials in the presence of various concentrations of ferrocyanide as a probe and various surface concentrations of cyt-c; then the standard tunneling ET and bimolecular rate constants are obtained as 3.4 ± 0.3 s-1 and (2.0 ± 0.5) × 107 cm3 mol-1 s-1, respectively.

This paper describes an electrochemically mediated enzyme reaction of polyethyleneglycol (PEG)-modified galactose oxidase (GAO) in organic solvents as well as in an aqueous solution. Catalytic currents were investigated in the presence of ferrocene derivatives as mediators and PEG-modified GAO in several organic solvents. The catalytic current due to the mediated enzyme reaction was obtained in acetonitrile, N,N-dimethylformamide, N,N-dimethylacetamide and dimethylsulfoxide (DMSO). Stability tests of PEG-modified GAO in organic solvents demonstrated that the initial Ik/Id value was highest in acetonitrile; however, it gradually decreased. The PEG-modified GAO was more stable in DMSO. Reactivities of several mediators were investigated. Although a positively charged mediator indicated high reactivity in the aqueous solution, non-charged mediators such as ferrocene dimethanol and n-butyl ferrocene showed the highest activity in organic solvents. Substrate specificity demonstrated that the catalytic activity for benzyl alcohol in acetonitrile was greater than in aqueous solution. The effect of water content in acetonitrile was investigated. The catalytic activity decreased with the increase in water content.

In this review, we summarize recent advances in nanoscale electrochemistry, including the use of nanoparticles, carbon nanomaterials, and nanowires. Exciting developments are reported for nanoscale redox cycling devices, which can chemically amplify signal readout. We also discuss promising high-frequency techniques such as nanocapacitive CMOS sensor arrays or heterodyning. In addition, we review electrochemical microreactors for use in (drug) synthesis, biocatalysis, water treatment, or to electrochemically degrade urea for use in a portable artificial kidney. Electrochemical microreactors are also used in combination with mass spectrometry, e.g., to study the mimicry of drug metabolism or to allow electrochemical protein digestion. The review concludes with an outlook on future perspectives in both nanoscale electrochemical sensing and electrochemical microreactors. For sensors, we see a future in wearables and the Internet of Things. In microreactors, a future goal is to monitor the electrochemical conversions more precisely or ultimately in situ by combining other spectroscopic techniques.

In this study, glassy carbon electrode modified with nano gold-crystal violet film has been used to detect arsenite (As (III)) in a model system and in groundwater samples. The modified electrode was characterized by scanning electrochemical microscopy (SECM) and electrochemical impedance spectroscopy (EIS). Using voltammetric measuring technique, linear response was obtained in a concentration range of 2.0?22.0 muM. The arsenite concentrations in groundwater samples varied between 2.4 muM to 4.8 muM. The sensitivity of the modified electrode for As (III) detection was 5.6 muA/muM cm2 and 0.8 muM concentration was found as lower limit of detection (LOD). The accuracy of the method was checked with standard method anodic stripping voltammetry (ASV). Groundwater samples were characterized with dynamic (DLS) and electrophoretic (ELS) light scattering measurements which have shown that particles present in different samples differ in size distribution and zeta potential which did not interfere with As (III) detection.

A simple electrochemical approach was used to evaluate the stability and porosity of titania and silica thin films spin coated on electrode surfaces. This approach involved monitoring the magnitude of the Faradaic current of diffusing redox probes at the modified electrode surfaces over the course of a week to 4.5 months. Relatively nonporous films were examined as well as films templated with polystyrene latex spheres. The results show that templated titania films were significantly more porous compared to non-templated films. After the defect sites in the templated films were blocked, their long-term stability in aqueous electrolyte was evaluated. For titania, blocking was done by spin coating a dilute titania sol on the top of the film whereas for silica, the film was soaked in octyltrimethoxysilane. Both types of titania films (templated and non-templated) were found to be significantly more stable than the corresponding silica films, showing no signs of deterioration in simple electrolyte solutions during the entire evaluation period. In contrast, silica films showed significant deterioration in as little as 3 days. The enhanced stability of the titania films relative to silica films in near neutral electrolyte solutions was attributed to the differences in the point of zero charge of the oxide films.

A surface-confined layer containing naphthoquinone was prepared by reacting 2,3-dichloronaphthoquinone with the amino tail groups of an aminoethanethiolate-modified vapor-deposited gold surface; this surface layer was then reacted with beta-ferrocenylethylamine. These modified gold electrodes were examined with cyclic staircase voltammetry in aqueous HClO4 at the completion of each step in this sequence of reactions. The voltammetric signature for the 2e-, 2H+ reduction of the quinoid redox centers disappeared after the ferrocene compound was reacted with the naphthoquinone surface layer; furthermore, the surface coverage of ferrocene was twice that expected on the basis of a 1:1 reaction between the surface-bound naphthoquinone and beta-ferrocenylethylamine. These results suggest that the latter reacts with the naphthoquinone carbonyl groups to form a surface-confined di-imine, which cannot be reduced within the electrochemical potential window of aqueous HClO4. In similar experiments, 2-[4?-(beta-ferrocenylethylaminocarbonyl)phenyl]-1,4-naphthoquinone and 2-[2?-(beta-ferrocenylethylaminocarbonyl)-ethyl]anthraquinone were synthesized and reacted with aminoethanethiolate-modified gold surfaces. When examined at a platinum electrode in nonaqueous solvents, both of the freely diffusing compounds exhibited two pairs of voltammetric waves characteristic of quinoid and ferrocene functionalities. However, only the ferrocene redox centers of the resulting surface-confined layers were electroactive, suggesting that the reaction of these compounds with the surface-confined aminoethanethiolate involves conversion of the quinoid carbonyls to imines.
