Study Results from Fudan University Update Understanding of Essential Amino Acids (An electrochemical sensor for simultaneous determination of ascorbic acid, dopamine, uric acid and tryptophan based on MWNTs bridged mesocellular graphene foam ...)

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Essential Amino Acids have been published. According to news reporting originating from Shanghai, People's Republic of China, by NewsRx correspondents, research stated, "A multi-walled carbon nanotubes (MWNTs) bridged mesocellular graphene foam (MGF) nanocomposite (MWNTs/MGF) modified glassy carbon electrode was fabricated and successfully used for simultaneous determination of ascorbic acid (AA), dopamine (DA), uric acid (UA) and tryptophan (TRP). Comparing with pure MGF, MWNTs or MWNTs/GS (graphene sheets), MWNTs/MGF displayed higher catalytic activity and selectivity toward the oxidation of AA, DA, UA and TRP."

Our news editors obtained a quote from the research from Fudan University, "Under the optimal conditions, MWCNs/MGF/GCE can simultaneously detect AA, DA, UA and TRP with high selectivity and sensitivity. The detection limits were 18.28 mu mol L-1, 0.06 mu mol L-1, 0.93 mu mol L-1 and 0.87 mu mol L-1, respectively."

According to the news editors, the research concluded: "Moreover, the modified electrode exhibited excellent stability and reproducibility."
