首先用水热法制备了Fe3O4纳米球，然后以制备的磁性Fe3O4纳米粒子为磁核，在高温高压反应釜中与葡萄糖反应，使其表面包覆一层聚糖，利用聚糖的还原性，让包覆后的粒子与AgNO3反应，制备出Fe3O4／Ag纳米复合粒子。用透射电镜（TEM）、X射线衍射仪（XRD）对所制备的材料的形貌和结构进行了表征。通过抑菌实验的测定，结果表明Fe3O4／Ag复合材料具有良好的抑菌活性。

We prepare Fe3O4 nanoparticles by solvothermal routes. We obtain Fe3O4/Ag nanocomposite with Fe3O4 nanoparticales as magnetic core, reaction with glucose in a high-temperture and high-pressure reactor and the coated nanoparticles reaction with AgNO3 by the reduction of chitosan. Their morphology and structure are characterized by transmission electron microscopy （TEM） and X-ray diffraction （XRD）. Determination of antibacterial test of minimal inhibitory concentration and minimum bactericidal concentration shows that composite materials Fe3O4/Ag have better antibacterial activity.
