Abstract

In this study we developed a novel synthesis called "ferrite route," by which we can fabricate Fe nanoparticles larger than 10 nm at a yield 10 times higher than that obtained by the above mentioned methods. Synthesis is made at 90degC, without using any hazardous materials. We found that the Fe nanoparticles via the ferrite route were more easily embedded in poly-glycidyl methacrylate (poly-GMA), a polymer exhibiting minimum "non-specific protein adsorption" that is a requisite for magnetic carriers for bio-screening.
