Pt and Pd nanotubes could be prepared rapidly with high yields and good uniformity through the reduction of metal precursors in the presence of ZnO nanowires as inexpensive sacrificial templates. The prepared nanotubes showed efficient electrocatalytic properties toward alcohol oxidation.

Che PtRu alloy nanoparticles were prepared by the spontaneous adsorption of Pt(acac)2 on the surface of freshly prepared octanethiolate-protected ruthenium (RuSC8) nanoparticles. UV–vis spectroscopic measurements suggested that the adsorption ...

Correction for 'Exploring the origins of the apparent "electrocatalytic" oxidation of kojic acid at graphene modified electrodes' by Luiz C. S. Figueiredo-Filho et al., Analyst, 2013, 138, 4436-4442.

A rapid, convenient and accurate method for the assessment of DNA methylation status is presented based on the direct electrocatalytic oxidation of DNA bases without any bisulfite conversion, PCR amplification or labeling procedures.

Gold-platinum nanowires are proposed as electrocatalysts for a real-time nonenzymatic impedancimetric detection of glucose. The electrochemical behavior of the obtained platform toward electrocatalytic oxidation of glucose, including a proposal for the detection mechanism, is shown.

This study reports a noncovalent functionalization of MWCNTs with a fluorinated cross-linked polymer coating of poly[cyclotriphosphazene-co-(4,4'-(hexafluoroisopropylidene)diphenol)] and their application as the support of Pt for electrocatalytic oxidation of methanol.

A newly-designed network of ternary Pd(2)/PtFe nanowires on a three-dimensional graphene framework has been fabricated via a dual solvothermal approach, which presents superior electrocatalytic activity towards the oxidation of formic acid.

We report on real-time electrochemical detection of individual DNA hybridization events at an electrode surface. The experiment is carried out in a microelectrochemical device configured with a working electrode modified with single-stranded DNA probe molecules. When a complementary DNA strand labelled with a catalyst hybridizes to the probe, an easily detectable electrocatalytic current is obs...

We propose chlorpromazine (CHP) as a new mediator for the rapid, sensitive, and highly selective voltammetric determination of homocysteine (Hcy) using multiwall carbon nanotube paste electrode (MWCNTPE). The experimental results showed that the carbon nanotube paste electrode has a highly electrocatalytic activity for the oxidation of Hcy in the presence of CHP as a mediator. Cyclic voltammetr...

Highly ordered Pd nanowire arrays (NWAs) prepared by electrodeposition method using the fresh prepared anodic aluminum oxide (AAO) as the template have been characterized by X-ray diffraction pattern (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscope (TEM), scanning electron microscopy (SEM), and electrochemical measurements. SEM results revealed that the brush-shap...
