Studies from Y.V. Bogachev and Colleagues Provide New Data on Nanoparticles

May 23, 2014

By a News Reporter-Staff News Editor at Science Letter -- Current study results on Nanoparticles have been published. According to news reporting originating in St. Petersburg, Russia, by NewsRx journalists, research stated, "Colloidal solutions of magnetic nanoparticles were studied as a promising magnetic resonance imaging (MRI) contrast agent. The problem of aggregative stability of solutions is considered."

The news reporters obtained a quote from the research, "Sol-gel synthesis of magnetite colloidal solutions stabilized by silica is described. Transmittance spectra were measured to analyze sedimentation of nanoparticles in magnetite-silica solutions of different compositions and concentrations. It is shown that the synthesized nanoparticles can be used as MRI contrast agents. The surface morphology and particle size of Fe3O4/SiO2 layers were estimated by atomic force mictroscopy (AFM) technique."

According to the news reporters, the research concluded: "The mechanism of magnetic-field-induced aggregation of Fe3O4/SiO2 nanoparticles into chain-like and fractal structures is described."
