Fe3 O4 nanocluster sphere was prepared by one-step solvothermal route in glycol with starch as the surfactant .The structure of as-prepared product was analyzed by means of X-ray diffraction ,Fourier transform infrared spectrometry ,and scanning electron microscopy ,and its thermal stability was evaluated by thermogravimetric analysis .Results indicate that as-pre-pared nanocluster sphere-like structure has a diameter of about 230 nm ,and the nanoparticles compromising the cluster sphere have a diameter of about 10 nm .Besides ,introducing starch helps to effectively improve the nanostructure and surface properties of as-prepared product . As-obtained Fe3 O4 nanocluster sphere possesses unique structure and surface properties and may find promising application in the field of biology .
