摘要
In this paper,it was found that Ru(H_2bpp)_2(PF_6)2(H_2bpp = 2,6-bis(pyrazol-3-yl)pyridine) complex had excellent electrochemical activity at the carbon paste electrode in the buffer solution of Tris-HCl(pH 7.0) with a couple reversible redox peaks at 0.296 V and 0.348 V,respectively.Voltammetry was used to investigate the electrochemical behavior of Ru(H_2bpp)_2(PF_6)_2 and the interaction between Ru(H_2bpp)_2(PF_6)_2 and bovine serum albumin(BSA).In the present of BSA,the oxidation peak current of Ru(H_2bpp)_2(PF_6)_2 complex was decreased linearly and the decrease of oxidation peak current of Ru(H_2bpp)_2(PF_6)_2 is proportional to BSA concentration from 0.1 to 2.5 mg/L with a detection limit 0.02 mg/L.
