摘要：
An improved method of preparing magnetite-dextran microspheres by ultrasonication is proposed. Several parameters were evaluated and the characteristics of the microspheres investigated by scanning electron microscope (SEM), atomic force microscope (AFM), particle size analyzer and magnetometer. The results show that the initial Fe/ dextran ratio is the most effective parameter for both the size and the magnetic properties. (c) 2005 Published by Elsevier B.V.
