Superparamagnetic Fe3O4–Ag hybrid nanocrystals as a potential contrast agent for CT imaging

Dispersed superparamagnetic Fe3O4–Ag hybrid nanocrystals were successfully synthesized by a seed-assisted hydrothermal strategy. The diameter of the Fe3O4–Ag nanocrystals is 10–20 nm, and the magnetization saturation is over 40 emu g−1. This facilitates their potential applications in magnetic resonance imaging for medical diagnosis.
