About the Preparation and Characteristics of Biocompatible Composite Magnetic Nanoparticles

ZHANG Ming-gang,ZHAO Guang-rong  
The experiment of synthesizing biocompatible composite magnetic nanoparticles successfully.The particles are formed by a~10nm magnetite nucleus and a~30nm biodegradable poly(lactic acid) polymer coating.The influence of central technical parameters is studied,and the appropriate reaction conditions are put forward: preparation of magnetite nanoparticles,the ratio of Fe~(2+)∶Fe~(3+) is 1∶1,and the surfactant is polyglycol;preparation of composite particles,the ratio of 5% solution of poly(lactic acid) in dichloromethane and 20% aqueous suspension of magnetite particles is 1∶4.The magnetism is determined by a Gouy magnetic balance,and the sample phase structure and particle sizes are determined by an X-ray diffraction(XRD) and a transmission electron microscopy(TEM).
