摘要：

Particularly uniform: Monodisperse ferrite microspheres can be synthesized to have diameters of about 200-800 nm (TEM image, left). High-resolution TEM analysis (image, right and inset) shows that each microsphere is a single crystal. Their hydrophilic and magnetic properties impart to the microparticles many potential uses in electronics and biomedicine. (Chemical Equation Presented) © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
