Magnetite nanocrystals have been widely used in many fields. Recently, a new magnetite nanocrystals, called magnetosome, has been found in magnetotactic bacteria. In this article, we researched on the properties of magnetosomes in detail, such as crystalline, morphology, crystal-size distributions, vitro cytotoxicity, and magnetic properties and quantified primary amino groups on the magnetosomes membrane surface 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. Key Words: magnetosome, synthetic magnetite, magnetotactic bacteria, properties
