By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators publish new report on Capillary Electrophoresis. According to news reporting from Gainesville, Florida, by NewsRx journalists, research stated, "Characterization of C-60 polyhydroxyfullerenes (PHF) prepared in alkaline media, preparation facilitated by phase-transfer catalyst, presents challenges in determining the chemical structure resulting from the possibility of multiple isomers or analogs with greater or fewer hydroxyl groups from a single reaction mixture. This paper presents the utilization of analytical methods employed in tandem, especially X-ray photoelectron spectroscopy, nuclear magnetic resonance spectroscopy, Fourier transform infrared spectroscopy for semi-quantitative analysis on the number of hydroxyl groups present in PHF."
The news correspondents obtained a quote from the research from the University of Florida, "Capillary Electrophoresis was used for purity estimation of the material. Multiple spectra and electropherograms were analyzed using a new simultaneous curve fitting method. The most accurate estimate of hydroxyl groups for C-60 polyhydroxy fullerenes obtained is between 16 and 18 allylic hydroxyl groups by combining analytical methods' results with 5 % accuracy. High precision (reproducibility) of the experiments is observed. Purity of 98 % is estimated by capillary electrophoresis. The size of PHF nanoparticles or aggregates has been determined by atomic force microscopy to be 7.4-14.2 nm. According to the elemental analysis the average probable empirical formula for the most pure PHF at pH 7.1 is C60O17H12Na5(NaHCO3)(3)(H2O)(13) and the average formula weight is 1,605.9 g/mol."
According to the news reporters, the research concluded: "This is the first thorough characterization of PHF in terms of purity."
