A New Method for the Rapid Synthesis of Water Stable Superparamagnetic Nanoparticles

Small changes—big effect: Superparamagnetic nanoparticles stable in water with mean hydrodynamic sizes of 37 and 70 nm have been obtained by small changes in the experimental setup (see figure). The particles show a great stability in water and a narrow size distribution. This new approach can be us...

Summary:Small changes—big effect: Superparamagnetic nanoparticles stable in water with mean hydrodynamic sizes of 37 and 70 nm have been obtained by small changes in the experimental setup (see figure). The particles show a great stability in water and a narrow size distribution. This new approach can be used not only as a standard procedure for the synthesis of hydrophillic nanoparticles, but as the starting point for further modifications of particle surfaces for molecular imaging applications.
