Nanoporous gold (np-Au), because of its high surface area-to-volume ratio, excellent conductivity, chemical inertness, physical stability, biocompatibility, easily tunable pores, and plasmonic properties, has attracted much interested in the field of nanotechnology. It has promising applications in the fields of catalysis, bio/chemical sensing, drug delivery, biomolecules separation and purific...

the objectives of this investigation are the studies on the effect of copper ion on photolytic degradation of ethylenediaminetertraaceticacid (edta), the effect of edta on electrolytic recovery of copper as well as the introduction of a novel combined photolytic and electrolytic cell system for simultaneous recovery of copper and the degradation of edta.in this experimental study, a photolytic ...

determined in the range 3 x 108-2 x lo9 bacteria ml-' with a 2 a precision of 16%. The use of phenazine ethosulphate as a mediator in the work reported here was probably the main cause of greater sensitivity (6 x 106-6 x lo8 bacteria ml-I). This work has demonstrated that bioelectrochemical detectors, working in either the poised-potential or fuel-cell mode, can rapidly and reproducibly determi...

Electrochemical microsensors are ideal to measure substances with low concentration in complex environments. The primary excitatory neurotransmitter L-glutamate is present in many foods as a distinctive flavour (enhancer) with a wide concentration range. In comparison to other methods, electrochemical sensors allow the rapid, precise, cost-effective, online measurement without any sample treatm...

An electrochemical 'Lab-on-a-chip' for water toxicity detection is presented. This miniaturized device containing an array of nano liter electrochemical cells, which integrates bacteria and can emulate physiological reactions in response to different chemicals. Bacteria, which have been genetically engineered to respond to environmental stress, act as a sensor element and trigger a sequence of ...

A sensitive electrochemical self-assembled peptide based biosensor was developed for detection of caspase 3 activity and apoptosis using the Asp-Glu-Val-Asp (DEVD) modified peptide and horseradish peroxidase (HRP) as cleaving and electron transfer (current amplifier) agents, respectively. Streptavidin coated magnetic beads (MB) were used to increase the loading efficiency of HRP on the DEVD mod...

We present an electronic structural analysis of an individual single-walled carbon nanotube (SWNT) employing electrochemical surface-enhanced Raman scattering (SERS). An isolated SWNT was supported on a well-defined Au nanodimer structure, which possesses a localized surface plasmon resonance (LSPR) field at the nanogap, and highly intense SERS spectra were measured for the SWNT at the gap regi...

Porous high surface area thin films of nanosheet-shaped monoclinic MoO(3) were deposited onto platinized Si substrates using patch antenna-based atmospheric microplasma processing. The films were characterized by high resolution transmission electron microscopy (HRTEM), scanning electron microscopy (SEM) and electrochemical analysis. The electrochemical analysis shows original redox peaks and h...
