A sensor for nitric oxide is reported that uses a novel redox matching mechanism to induce a resistance change upon binding this important ligand to cobalt.

During the regeneration of the oxidized dye in dye-sensitized solar cells, the redox couple of I(-)/I(3)(-) reduces the photo-oxidized dye. The simplest mechanism would be a direct charge-transfer mechanism from I(-) to D(+) [D(+) + I(-) → D(0) + I], called the single iodide process (SIP). However, this is an unfavorable equilibrium because the redox potential of I(•)/I(-) is 1.224 V vs SHE, wh...

Membrane lipid rafts (LRs) have been demonstrated to be importantly involved in transmembrane signaling in a variety of mammalian cells. Many receptors can be aggregated within the LR clusters to form signaling platforms. Currently, LRs were reported to be clustered to aggregate, recruit, and assemble NADPH oxidase subunits and related proteins in various cells in response to various stimuli, f...

Protein cysteines can undergo various forms of oxidation, some of them reversible (disulphide formation, glutathionylation and S-nitrosylation). While in the past these were viewed as protein damage in the context of oxidative stress, there is growing interest in oxidoreduction of protein thiols/disulphides as a regulatory mechanism. This review discusses the evolution of the concept of redox r...

A luminescent two-dimensional (2D) coordination polymer is demonstrated to be a selective sensing material for the straightforward detection of nitrobenzene via a redox fluorescence quenching mechanism.

A sulfur redox process has been developed between sulfinate and thiosulfate, which efficiently affords diverse unsymmetrical disulfides and provides a new method to modify pharmaceuticals and natural products without requiring an extra oxidant or reductant. Gram-scale investigation further demonstrates the practicality and application potential of this process. Isolated key intermediates and a ...

Mammalian cells do not survive in the absence of redox reactions; oxidation and reduction predominate in the swamp of metabolic biochemical reactions inside the cell. In a situation which is less stoichiometric, subtle alterations of the redox status in the intracellular environment also have significant impacts on cell biology. Changes in the intracellular redox status can be assessed by quant...

In mixtures of trichloroacetate ion and trichloroacetic acid in acetonitrile, trichloromethyl radicals are produced as a result of the redox reaction between the acid and its conjugate base. The reaction follows a loop mechanism in which the trichloroacetic acid is slowly consumed by proton reduction while the trichloroacetate ion is oxidized like in an electrochemical Kolbe reaction. The hydro...
