Magnetic La1-xSrxMnO3 nanoparticles as contrast agents for MRI: The parameters affecting 1H transverse relaxation
Original language description
Magnetic nanoparticles of the La1-xSrxMnO3 perovskite phase (x = 0.20-0.45) were synthesized by a sol-gel method followed by thermal and mechanical treatments. The particles were coated with a uniform silica shell, and differential centrifugation yieldeda product with high colloidal stability in water. XRD data showed that the mechanical processing did not affect the lattice parameters of the magnetic cores but only reduced their mean size dXRD. The magnetic properties of the bare particles were mainlycontrolled by the chemical composition and were also affected by the size of the particles. Subsequent silica coating led to an effective decrease in magnetization. Relaxometry measurements were focused primarily on colloids using magnetic cores of thesame size (dXRD = 20 nm) and different compositions, and coated with a shell measuring approximately 20 nm in thickness. The exceedingly high transverse relaxivities (r2(20oC) = 290-430 s-1mmol-1L at B0 = 0.5 T) of the samples exhibited p
