英文摘要	Monodispersed magnetite (Fe3O4) particles were synthesized using a high-temperature hydrolysis reaction with the assistance of ethylenediaminetetraacetic acid (EDTA) as capping ligands.These particles were composed of small primary nanocrystals and their sizes could be tuned from about 400 to about 800 nm by simply changing the EDTA or precursor concentration. Surface-tethered EDTA made the particles highly water-dispersible.The asprepared magnetite particles also showed superparamagnetic behavior at room temperature, and their magnetic properties were size dependent. In addition, the particles had a strong response to external magnetic field due to their high magnetization saturation values.These properties were very important for some potential biomedical applications, such as magnetic separation and magnetic-targeted substrate delivery. ? 2014 Yi et al.
