Аннотация:Herein, we report a novel one-step solvothermal synthesis of magnetitenanoclusters (MNCs). In this report we discuss synthesis, structure and properties of MNCs andcontrast enhancement in T2-weighted MR images using magnetite nanoclusters. Effect of differentorganic acids, used as surfactants, on size and shape of MNC was investigated. Structure andproperties of samples were determined by magnetic measurements, TGA, TEM, HRTEM, XRD,FTIR, MRI. Magnetic measurements show that obtained MNCs have relatively high saturationmagnetization values (65.1 – 81.5 emu/g) and dependence of the coercive force on the averagesize of MNCs was established. MNCs were transferred into aqueous medium by Pluronic F-127and T2-relaxivity values were determined. T2-weighted MR phantom images clearly demonstratedthat such magnetite nanoclusters can be used as contrast agents for MRI.
