Abstract

Cubic magnetic nanoparticles with average sizes of 16.1 ± 2.2, 22.3 ± 3.5, and 37.4 ± 5.2 nm are obtained by a variety of means. The magnetic characteristics of these nanoparticles are studied as well. The samples are probed via X-ray diffraction to establish structural features, and the specific absorption rate (SAR) is analyzed as a function of the frequency and induction of an alternating magnetic field.

Abstract

Results are presented from synthesizing and characterizing magnetite nanoparticles with spherical, cubic and octahedral geometry. Magnetic properties (saturation magnetization, residual magnetization, and coercive force), cytotoxicity, and T2 relaxivity are measured for the synthesized nanoparticles. They are characterized via X-ray diffraction and dynamic light scattering (hydrodynamic size and zeta potential). The effect the shape of the nanoparticles have on the values of T2 relaxivity is analyzed. Nontoxic magnetite nanoparticles coated with copolymer are excellent contrast agents for magnetic resonance imaging (MRI) and show better contrast properties than their commercial analogs (Rezovist, Ferumoxytol, Feridex).
