    ABSTRACT: Eugenol electropolymerization conditions on multiwalled carbon nanotube based glassy carbon electrode (MWNT/GCE) have been found. The polyeugenol/MWNT/GCE shows reversible redox steps of o-quinone fragment in acidic media. Natural phenolic antioxidants are oxidized on polyeugenol/MWNT/GCE at 0.52 V excluding resveratrol (0.62 V). Differential pulse voltammetry on polyeugenol/MWNT/GCE was applied for the evaluation of wine antioxidant capacity (AOC). The AOC was expressed in catechin equivalents per 1 L of wine. The linear dynamic range is 1.00–250 µM with LOD and LOQ of 0.21 and 0.71 µM of catechin, respectively. Positive correlations for AOC with antioxidant activity (r=0.9840) and total phenolics content (r=0.9944) were observed.

    ABSTRACT: This paper made a comparative study of new matrices of nanostructured materials (multiwall carbon nanotube, fullerene and hydroxylated fullerene) aiming to compare them when employed in the process of immobilization of enzyme horseradish peroxidase (HRP) on the development of amperometric biosensors for the determination phenolic compounds. The results confirm that all the three nanostructured matrices used in the preparation of the biosensor show improvements when acting as a transducer stabilizer and immobilization matrix, comparing to the electrode of carbon paste. Regarding the performance of these matrices it is verified that the developed biosensor employed the multiwall carbon nanotube as matrix immobilized enzyme HRP has shown the best sensitivity for the molecule of phenol (33 nA cm−2 µmol−1 L), however, regarding the range of linear response, the elaborated biosensor containing the hydroxylated fullerene has shown the best response (5–200 µmol L−1). In terms of operational stability, the biosensors maintained their responses around 95 % after more than 200 analyzes. It is also important to mention that in all the cases, the association with the graphite powder improves the answers of the biosensors around 10 to 15 %.

    ABSTRACT: Organic fluorescent dyes are widely used in single molecule localization microscopy, where their performances are determined by the photophysical properties. Herein, we utilized a sensitive method to modulate the fluorescence of organic dyes by external potentials using a combination of electrochemical cell and super-resolution fluorescent microscopy. Cy5 (cyanine dye) was chosen as a model molecule considering its wide application and commercial availability. We applied different potentials on the Au electrode to change the Coulombic charge microenvironment of Cy5. When the electrode potential was adjusted negatively, Cy5 displayed a better photostability. This method is proved effective in adjusting the fluorescence of organic dyes.

    ABSTRACT: Well-defined three-dimensional (3D) PdCu bimetallic alloy nanosponges (BANs) with highly porous structure was reported through a rapid and general strategy. Significantly, the as-prepared PdCu BANs exhibited greatly enhanced activity and stability than commercial Pd/C catalyst towards ethanol electrooxidation in an alkaline medium. Pd1Cu1 shows higher active area and better electrocatalytic activity than Pd1Cu2 and Pd2Cu1. This result demonstrates the potential of applying these PdCu BANs as effective electrocatalysts for direct alcohol fuel cells (DAFCs).

    ABSTRACT: A new electroactive disulfide-confined aryl diazonium (DSAD) salt was synthesized and used as a linker for biomolecules immobilization to prepare two kinds of immunoassay platforms. DSAD was electrodeposited on ITO electrode surfaces by cyclic voltammetry. Disulfide group of DSAD attached on the surfaces were electrochemically oxidized into thiosulfinate or thiosulfonate groups. For the first work, a detection of rabbit antigen was performed on ITO microelectrodes array by spatially-selective approach. In the second work, DSAD was deposited on electrochemically reduced graphene oxide-modified ITO surfaces, which were used as a platform for electrochemical sandwich immunoassay for detecting mouse antigen.

    ABSTRACT: We report on the design of a UO22+-selective electrode based on the use of UO22+ imprinted polymer nanoparticles (IP-NPs), and its application for the differential pulse adsorptive cathodic stripping voltammetry determination of uranyl ions. A carbon paste electrode was modified with the IP-NPs, and differential pulse adsorptive cathodic stripping voltammetry was applied as the detection technique after open-circuit sorption of UO22+ ions. The modified electrode responses to UO22+ was linear in the 0.1 µg L-1 to 10 µg L-1 and in the 0.01 mg L-1 to 10 mg L-1. The method detection limit of the sensor was 0.03 µg L-1.

    ABSTRACT: Bromophenol blue (BPB) was electropolymerized onto a Au substrate. The effects of voltammetric cycle number, BPB concentration, and pH on film thickness, density, optical absorption, and electrochemical susceptibility were evaluated, and favorable deposition conditions were identified. Quantitative measurement of the film mass via quartz crystal microbalance enabled determination of the molar volume and revealed a strong dependence of film density with deposition pH. Finally, electrochemical control of the optical properties of BPB films was demonstrated via in situ spectroelectrochemistry. We believe this is the first demonstration of electropolymerization of pure BPB on Au, and thus the first demonstration of poly(BPB) as an electrochemically switchable optical coating.

    ABSTRACT: A new environmentally friendly Au nanoparticles (Au NPs) synthesis in glycerol by using ultraviolet irradiation and without extra-added stabilizers is described. The synthesis proposed in this work may impact on the non-polluting production of noble nanoparticles with simple chemicals normally found in standard laboratories. These Au NPs were used to modify a carbon paste electrode (CPE) without having to separate them from the reaction medium. This green electrode was used as an electrochemical sensor for the nitrite detection in water. At the optimum conditions the green sensor presented a linear response in the 2.0×10−7–1.5×10−5 M concentration range, a good detection sensitivity (0.268 A L mol−1), and a low detection limit of 2.0×10−7 M of nitrite. The proposed modified green CPE was used to determine nitrite in tap water samples.

    ABSTRACT: A sensitive and selective photoelectrochemical sensor has been developed. Negatively charged, citrate-capped CdS quantum dots (QDs) are assembled layer-by-layer onto indium tin oxide (ITO) electrodes precoated with positively charged poly(diallyldimethylammonium chloride). By exposing the modified photoelectrochemical electrodes to a Na2S solution, QDs can be covered with excess S2− ions. The weakly bound S2− ions are easily replaceable with a sulphydryl-containing analyte, and the photocurrent decrease is proportional to the analyte concentration. The detection limit is 0.4 nM for cysteine with a linear range of 1.0–100.0 nM. The level of cysteine in human serum samples has been quantified.

    ABSTRACT: The present work describes the development of a selective, sensitive and stable sensing microsensor for scanning electrochemical microscopy (SECM) to measure H2O2 during electrochemical reduction of oxygen. The microsensor is based on graphene and Poly(3,4-ethylenedioxythiophene) composite as support to iron (III) hexacyanoferrate (II) (PEDOT/graphene/FeIII4[FeII(CN)6]3 microsensor). The electrochemical properties of the PEDOT/graphene/FeIII4[FeII(CN)6]3 microsensor were investigated by cyclic voltammetry (CV) and scanning electrochemical microscopy (SECM). The PEDOT/graphene/FeIII4[FeII(CN)6]3 microsensor showed an excellent electrocatalytic activity toward hydrogen peroxide (H2O2) reduction with a diminution of the overpotential of about 500 mV in comparison to the process at a bare gold microelectrode. The microsensor presented excellent performance for two dimensional mapping of H2O2 by SECM in 0.1 mol L−1 phosphate buffer solution (pH 7.0). Under optimized conditions, a linear response range from 1 up to 1000 µmol L−1 was obtained with a sensitivity of 0.08 nA L µmol−1 and limit of detection of 0.5 µmol L−1.

    ABSTRACT: This study examined the performance of four conducting metal oxide electrodes for the direct electrochemical analysis of sulfide; the electrode materials studied were indium tin oxide (ITO), fluorine doped tin oxide (FTO), aluminum doped zinc oxide (AZO) and gallium doped zinc oxide (GZO). Cyclic voltammetry (CV) results obtained using the ITO, AZO, GZO and FTO electrodes showed direct electrooxidation peak potential of sulfide at 381, 507, 400, and 850 mV vs. Ag/AgCl, respectively; however, the less positive oxidation potential and high catalytic current response of the ITO electrode made it the electrode of choice for the direct oxidation of sulfide. The effects of different electrolytes and buffer solutions on the CV responses were also evaluated. A linear concentration range up to 350 µM and a detection limit of 8.0 µM were achieved. CV response was highly reproducible, remaining unaffected even after 50 measurements. The sensor was found to have good selectivity, with no interference from sulfite, sulfate or chloride ions. The present findings demonstrate that the bare ITO electrode can be used as the basis of an inexpensive, sensitive, selective and robust sulfide sensor.

    ABSTRACT: Cells have a net negative outer charge which gives rise to a potential difference in a potentiometric set up. Here, Triton X-100 was used as a model toxin and the cell death was monitored by the potential change, noticed as decrease in negativity. Hence, cytotoxicity can be tested in vitro and real-time using potentiometry. However, silver ions (Ag+) and/or silver chloride ions (AgCl2)−1 lead to cell death when we used the standard Ag/AgCl reference electrode with 3 M NaCl as filling solution. Our further experimentation showed that PBS as filling solution was biocompatible and also gave stable potentiometric profiles.
