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...

    Electrochemical aptamer-based sensors attract a lot of interest as useful methods because of their low cost, accuracy, sensitivity, and simplicity. An electro-active redox molecule comprises the main part of the electrochemical-based sensors. Ferrocene is one of the most popular redox molecule used in biosensor fabrication. But, instability of ferrocenium ion in strong nucleophilic reagents...

The cyclic voltammetry of both bulk manganese sulfate (BMS) and nano manganese sulfate (NMS) were studied using 0.1M KCl supporting electrolyte and glassy carbon working electrode. The redox behavior for both bulk (BMS) and MnSO4 (NMS) sulfate was studied voltammetrically in presence and absence of Doxorubicin (DR) using three electrodes system, silver- silver chloride (Ag/AgCl), pla...

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...

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 of redox potential for 9-ag-guan...

Lescuraea morrisonensis (Takaki) Nog. fo. sichuanensis Wang, Hu & Redfearn reported from mainland China is synonymized to Actinothuidium hookeri (Mitt.) Broth. Filiform branched paraphyllia and triangular stemleaves which characterize A. hookeri are distinguishable from unbranched foliose paraphyllia and ovate-lanceolate stem-leaves of Lescuraea morrisonensis.

Eu(II) -based contrast agents offer physiologically relevant, metal-based redox sensing that is unachievable with Gd(III) -based contrast agents. To evaluate the in vivo contrast enhancement of Eu(II) as a function of injection type, we performed intravenous, intraperitoneal, and subcutaneous injections in mice. Our data reveal a correlation between reported oxygen content and expected rates of...
