RESEARCH ON THE STRUCTURE AND PERFORMANCE OF BACTERIAL MAGNETIC NANOPARTICLES

摘要：

Magnetite nanocrystal has been widely used in many fields. Recently, a new magnetite nanocrystal, called magnetosome, has been found in magnetotactic bacteria. In this article, we researched on the properties of magnetosomes detailedly, such as crystalline, morphology, crystal-size distributions, vitro cytotoxicity, and magnetic properties and quantified primary amino groups on the magnetosomes membranesurface by fluorescamine assay for the first time. From the results, it was clear that magnetosomes have more potential in the biomedical applications than synthetic magnetite.
