A sensitive amperometric biosensor based on gold nanoelectrode array (NEA) was investigated. The gold nanoelectrode array was fabricated by template-assisted electrodeposition on general electrodes, which shows an ordered well-defined 3D structure of nanowires. The sensitivity of the gold NEA to hydrogen peroxide is 37 times higher than that of the conventional electrode. The linear range of th...

In this study a novel method was developed to fabricate cadmium sulfide nanoparticles/multiwalled carbon nanotubes composite modified gold electrode (CdSNPs/MWCNTS/AuE) to measure trace amounts of norepinephrine(NE), indomethacin (IND), and uric acid (UA) simultaneously. Electrochemical investigations were carried out using cyclic voltammetry (CV), differential pulse voltammetry (DPV) and chron...

In this paper we report for the first time the design, fabrication and characterization of an optically transparent electrode array for micro-electrocorticography. We present a 49-channel μECoG array with an electrode pitch of 800 μm and a 16-channel linear μECoG array with an electrode pitch of 200 μm. The backing material was Parylene C. Transparent, sputtered indium tin oxide (ITO) was used ...

A new composite film-modified electrode was prepared by the electropolymerisation of poly(3,4-ethylenedioxythiophene) (PEDOT) and superconductive carbon black (SCB) on a gold electrode. The PEDOT-SCB/Au electrode exhibited excellent ability towards the electrocatalytic oxidation of ascorbic acid, in terms of a 480 mV shift of the oxidation potential in the negative direction, and a dramatically...

We report the design and characterization of a metal ion-imidazole self-assembled monolayer on a gold electrode. The resultant monolayer is well-suited for direct immobilization of histidine and methylene blue-modified peptides.

Anion templation is used to assemble novel redox-active bis-ferrocene functionalised rotaxane self-assembled monolayers (SAMs) on to gold electrode surfaces; after template removal, the unique SAM rotaxane binding domain is capable of selectively sensing chloride ions electrochemically.

Intense electrogenerated chemiluminescence of a bis-cyclometalated alkynylgold(iii) complex using tri-n-propylamine as a co-reactant at the fluorosurfactant-modified gold electrode has been observed for the first time.

the reduction process for some quinones has been studid by cyclic voltammeby, rotating disk electrode voltammetry and chronopotentiometry in chloroform at platinum, gold and glassy carbon electrodes using tetrabutylmonium perchlorate (tb ap) as supporting eiectrolyte. the results obtained from this study reveal that the reduction of the quinones is two one-electron processes, the first reductio...

AIMS This prospective, multicentre study (PRECISION GOLD) evaluated the incidence of asymptomatic cerebral embolism (ACE) after pulmonary vein isolation (PVI) using a new gold multi-electrode radiofrequency (RF) ablation catheter, pulmonary vein ablation catheter (PVAC) GOLD. Also, procedural efficiency of PVAC GOLD was compared with ERACE. The ERACE study demonstrated that a low incidence of A...

We developed a multiplex enzyme-based electrochemical genosensor for sequence-specific detection of multiplex linear-after-the-exponential-PCR amplicons that targeted toxigenic Vibrio cholerae O1 and O139 using novel screen-printed gold electrode bisensors.
