There is a large interest in functionalized magnetic nanoparticles as supports for organic synthesis, reagents, catalysts, and molecular scavengers. The magnetic supports afford easier separation schemes following synthetic organic procedures. Degussa chemical company has provided samples of magnetic nanoparticles nested in silicate; there are several magnetite domains in each silica matrix that resembles the "plum pudding" model. Herein is reported the size ranges of these particles and their solubility in organic solvents such as toluene, when functionalized with small molecule modifiers.
