Researchers from Xuchang University Report New Studies and Findings in the Area of Catecholamines

May 14, 2014

By a News Reporter-Staff News Editor at Biotech Week -- Researchers detail new data in Catecholamines. According to news reporting originating from Xuchang, People's Republic of China, by NewsRx correspondents, research stated, "We have developed hexadecyl trimethyl ammonium bromide (CTAB) functionalized graphene oxide (GO)/multiwalled carbon nanotubes (MWNTs) modified glassy carbon electrode (CTAB-GO/MWNT) as a novel system for the simultaneous determination of dopamine (DA), ascorbic acid (AA), uric acid (UA) and nitrite (NO2-)."

Our news editors obtained a quote from the research from Xuchang University, "The combination of graphene oxide and MWNTs endow the biosensor with large surface area, good biological compatibility, electricity and stability, high selectivity and sensitivity. In the fourfold co-existence system, the linear calibration plots for AA, DA, UA and NO2- were obtained over the range of 5.0-300 mu M, 5.0-500 3.0-60 mu M and 5.0-800 mu M with detection limits of 1.0 mu M, 1.5 mu M, 1.0 mu M and 1.5 mu M, respectively."

According to the news editors, the research concluded: "In addition, the modified biosensor was applied to the determination of AA, DA, UA and NO2- in urine samples by using standard adding method with satisfactory results."
