Water-soluble l-cysteine-coated FePt nanoparticles as dual

MRI and CT imaging of Cys-coated FePt NPs in cells. In a typical MRI measure, glioma cells were incubated with FePt-Cys NPs dissolved in DMEM at different iron concentrations (0, 5, 10, 15, and 20 μg/mL) at 37°C for 3 hours. After that, the cells were washed with phosphate-buffered saline (0.1 M, pH =7.4) three times.

Ferromagnetic FePt-Nanoparticles/Polycation Hybrid

The present Article describes the synthesis of ferromagnetic capsules approximately 330 nm in diameter with a nanometer-thick shell to apply to magnetic carriers in a magnetically guided drug delivery system. The magnetic shell of 5 nm in thickness is a nanohybrid, composed of ordered alloy FePt nanoparticles of approximately 3−4 nm in size and a polymer layer of a cationic polyelectrolyte

FePt nanoparticles formed in Al2O3 by ion beam synthesis

FePt alloy formation does not occur during annealing in an oxidizing environment. Instead, the implanted Pt precipitates out forming oriented Pt nanoparticles and the implanted Fe redistributes with ∼40% segregating to the surface where it forms epitaxial α-Fe2O3 precipitates at the surface; the remainder of the implanted Fe remains in the bulk, most likely in solid solution in the matrix.
