The increasing needs of personalized therapies have recently stimulated impressive advances in research and development of portable point-of-care biosensors for realtime monitoring as well as biosensors for drug development [1, 2]. Enzymatic amperometric biosensors based on the enzyme family cytochrome P450 (CYP) have drawn increasing attention because CYP is a monooxygenase enzyme primarily in...

Crystals of graphite nanosheets, achieved via a simple ball milling approach, show a significant size effect in electrocatalytic activation of oxygen.

Oxygen (O2) is the most abundant element in the Earth’s crust. The oxygen reduction reaction (ORR) is also the most important reaction in life processes such as biological respiration, and in energy converting systems such as fuel cells. ORR in aqueous solutions occurs mainly by two pathways: the direct 4-electron reduction pathway from O2 to H2O, and the 2-electron reduction pathway from O2 to...

the combination of graphene and nickel oxide nanoparticles yields nanostructured electrochemical sensor formed a novel kind of structurally uniform and electrocatalytic activity material. in cyclic voltammetry studies, in the presence of epinephrine, nickel oxide / graphene  composite modified electrode shows a significantly higher current response for epinephrine oxidation. based on differenti...

A new double-Keggin-ion-templated, molybdenum-oxide-based organic-inorganic hybrid compound has been hydrothermally synthesized and its electrocatalytic properties investigated.

Amorphous FeNiPt nanoparticles with tunable length have for the first time been reported to exhibit excellent electrocatalytic performance in the electrochemical determination of thiols.

In view of their possible use as electrocatalysts, several oxides with the fluorite or pyrochlore structure were investigated. Part I of this paper deals with the synthesis, characterization and electrical conductivity of these materials. All lanthanide titanates investigated (partly doped with Bi) show the pyrochlore structure and are poor conductors, except for the compounds containing Tb. Fo...

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 ...

The effects of ionic liquids (ILs) on the catalytic activity of enzymes were studied by approaches of electrochemistry and quantum chemistry calculation in this work. Three types of ILs, namely, [bmpyri]BF(4), [bmpyrro]BF(4), and [bmim]BF(4), were selected to address the effects of different types of ILs on the electrocatalytic activity of glucose oxidase (GOx) toward the oxidation of glucose. ...

In this work, a networked MoS2/CNT nanocomposite has been synthesized by a facile solvothermal method. The as-prepared sample exhibits high catalytic activity for electrocatalytic hydrogen evolution.
