By a News Reporter-Staff News Editor at Science Letter -- Data detailed on Tryptamines have been presented. According to news originating from Kwangju, South Korea, by NewsRx correspondents, research stated, "Graphene oxide (GO) has treated with methylene diphenyl diisocyanate (MDI) and subsequent 1,4-butanediol (BD) to create an anchoring OH site on the surface of GO (GO-MDI-OH). The OH groups of GO-MDI-OH were the initiators of the polymerization of poly(lactic acid) (PLA)."
Our news journalists obtained a quote from the research from Chonnam National University, "The subsequent GO-g-PLA was synthesized by the polymerization reaction in the presence of GO-MDI-OH and PLA. The synthesized materials were characterized via H-1-NMR, Fourier transform infrared spectroscopy (FT-IR), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), thermal analysis (differential scanning calorimeter (DSC), and thermogravimetric analysis (TGA)). The surface morphologies and degree of dispersions at G-g-PLA-metals were observed using a field emission scanning electron microscope (FE-SEM) and a transmission electron microscopy (TEM). The electrical conductivity of G-g-PLA-Pd was largely enhanced compared with those of GO and GO-g-PLA. G-g-PLA-Pd was used for the electrochemical detection of serotonin. Electrocatalytic activities were verified from the cyclic voltammetry (CV) and amperometric response in a 0.1 M phosphate buffer solution (PBS)."
According to the news editors, the research concluded: "A significantly higher concentration range (0.1-100.0 mu M) and a lower detection limit (8.0 x 10(-8) M, where s/n = 3) were found at the G-g-PLA-Pd modified glassy carbon electrode (GCE)."
