Jun 02, 2010 In this study, we prepared biocompatible, water-soluble, superparamagnetic, manganese-doped, magnetism-engineered iron oxide MnMEIO nanocrystals with reactive moieties. This was achieved via a one-pot synthesis protocol by thermally decomposing metal acetylacetonate precursors in 2-pyrrolidone in the presence of polyethylene glycol diacid. Using carbodiimide, we achieved nanocrystals
