摘要： 细胞色素C(Cyt.C)在电极界面上的电子传递十分缓慢,只有在适当的电子迁移中介体(Mediator)或促进剂(Promoter)参与下才能以较快的速度进行反应,本文报道了以4,4′-二硫基联吡啶(PySSPy)作电极反应促进剂。

Abstract: The electrochemical behavior of horse heart Cytochrome Cwas investigated in the presence of 4,4' -Dithiodipyridine as an electron transfer promoter on the gold minigrid optical transparent thin-layer electrode (Au-OTTLE). The formal potential E0' and electron transfer number n of the redox reaction of Cytochrome Cwere measured as 50 mV(vs. Ag/AgCl) and 1 respectively by thin-layer spectroelectrochemistry on Au-OTTLE. These data were also compared with the cyclic voltammetric results observed on Au-OTTLE > Au-microdisk electrode, and Au-disk electrode.
