One‐Nanometer‐Scale Size‐Controlled Synthesis of Monodisperse Magnetic Iron Oxide Nanoparticles

Accurate to size: Monodisperse magnetic iron oxide nanoparticles with a continuous size spectrum of 6–13 nm have been synthesized by a procedure similar to seed-mediated growth and characterized by transmission electron microscopy (see picture) and magnetic measurements. This method yields monodisperse nanoparticles directly without a size-selection process.
