Abstract

Planning a dopamine biosensor by single-walled carbon nanotube (SWNTs) additionally hemoglobin (Hb) experimented. Cyclic voltammetry (CV) for entirety electrochemical research were functioned. A standard three-electrode cell was operated during the analyses, Hb- carbon paste electrode (CPE) or SWNTs-Hb changed CPE as a working electrode, a saturated calomel electrode (SCE) as a reference electrode, and a platinum electrode as a counter electrode. Oxidation peak potential (Epa) as well as reduction peak potential (Epc) were between -350 also -400mV, respectively, furthermore the peak-to-peak disjunction (Delta Ep) was 50mV. To check the catalytic behavior of Hb, cyclic voltammograms of the SWNTs-Hb changed carbon paste electrode were examined in a solution with various concentration of dopamine. The outcomes demonstrate that dopamine displayed a linear association for diverse concentrations of dopamine in the level of 2 to 11 mM.
