quinones are a class of compounds which have widespread importance in chemistry, biology and medicine. because of their appropriate performance in electron transferring rate, quinones are among the most applicable mediators in biosensors. recently, the effects of different non-metal substitutions on redox potential of quinone have been investigated to design suitable mediators for different ele...

Electrode potential of 2-(2,3-dihydroxy phenyl)-1,3-dithiane (DPD) was investigated by means of cyclic voltammetry (CV) at various potential scan rates. The calculated value was compared with the experimental value obtained by cyclic voltammetry (CV). All experiments were done in aqueous phosphate buffer solutions at different pHs. The experimental redox potential of DPD was obtained to be 0.75...

the sexual maturation and spawning period of blood cockle in matang mangrove estuary was studied by naked eye and histological observations of the gonads from july 2010 to april 2011. the high spawning period was from november to february. however, at one station where bottom sediment exhibited a severe reduction in potential of −100 mv lower, immature individuals were common. these results sug...

Due to some important applications of guanine electrode in scientific and technology research such as electro-chemical DNA based biosensors, and a problem of high redox potential of guanine (0.81 V), our research study concentrates on reducing guanine redox potential by substituting Cu, Ag, Au, CH3, C2H5 and Cl on sites of 1, 2 and 9 of guanine. A 5.0% reduction...
