Highly sensitive electrochemical electrodes for glucose detection were developed by using Au nanoclusters (NCs) to modify nitrogen-doped diamond-like carbon thin films (DLC:N/Au). The DLC:N/Au electrodes were prepared with a filtered cathodic vacuum arc process followed by electrodeposition and characterized by X-ray photoelectron spectroscopy, Raman spectroscopy, and scanning electron microsco...

In situ electrochemical surface enhanced Raman spectra (SERS) for an immobilized monolayer of a flavin analogue (isoalloxazine) at nanostructured silver surfaces are reported. Unique in the present study, the flavin is not directly adsorbed at the Ag surface but is attached through a chemical reaction between cysteamine adsorbed on the Ag surface and methylformylisoalloxazine. Even though the f...

Automated systems for electrochemical synthesis and high throughput screening of catalytic materials were developed and used to prepare a library of nanoparticulate gold supported on TiO2. A two-dimensional array (library) of Au was synthesized by pulsed cathodic electrodeposition onto a thermally oxidized titanium dioxide substrate. Variations in particle size across the library were created b...

In this study, a high sensitive and selective hydrogen peroxide (H2O2) sensor was successfully constructed with Pt-Au bimetallic nanoparticles (Pt-Au NPs)/reduced graphene sheets (rGSs) hybrid films. Various molar ratios of Au to Pt and different electrodeposition conditions were evaluated to control the morphology and electrocatalytic activity of the Pt-Au bimetallic nanoparticles. Upon optima...

An aqueous sol-gel route has been developed for electrochemically controlled deposition onto micro and nanofabricated electrodes. TEOS and MeTEOS were hydrolyzed under acidic conditions, and alcohol products were removed by distillation. The resulting clear sol has a hydrolysis ratio between 40 and 45. Following hydrolysis, pH was raised to 5.0 with addition of potassium hydroxide. At room temp...

PURPOSE Regenerative medicine will benefit from technologies capable of fabricating soft matter to have appropriate architectures and that provide the necessary physical, chemical and biological cues to recruit cells and guide their development. The goal of this report is to review an emerging set of biofabrication techniques and suggest how these techniques could be applied for the fabrication...

The formation of tin dendritic nanostructures by electrolysis from the alkaline electrolyte has been investigated. Morphology and structure Sn dendrites produced applying both potentiostatic galvanostatic regimes are characterized SEM XRD, respectively. Depending on applied cathodic potentials, three types were obtained: (a) needle-like spear-like, (b) fern-like, (c) stem-like dendrites. very b...

This study has examined the pulse electrodeposition of copper from a deep eutectic solvent. Pulse plating parameters were selected using methodologies originally developed for aqueous solutions, including constraints arising double layer charging and mass transport effects. Although could be deposited under nearly all conditions, in many instances only partial was observed current efficiencies ...

A magnetic nanocomposite film with the capability of reversibly collecting functionalized magnetic particles was fabricated by simultaneously imposing two orthogonal stimuli (electrical and magnetic). We demonstrate that cathodic codeposition of chitosan and Fe3O4 nanoparticles while simultaneously applying a magnetic field during codeposition can (i) organize structure, (ii) confer magnetic pr...
