Preparation and physical characterization of magnetite nanoparticles (MNP) with Aminosilane shell — •Maryam Youhannayee¹, Stanislav Emelianov¹, Robert Rabenalt², and Mathias Getzlaff¹ — ¹Institute für angewandte physik, Heinrich-Heine-universität Düsseldorf — ²Klinik für Urologie, Universitätsklinikum Düsseldorf

Magnetite Nanoparticles are widely studied because of their fascinating application and also biocompatibility and low toxicity in different fields of biology and medicine. These nanoparticles covered with Aminosilane are perfect candidates for hyperthermia therapy due to a nearly perfect prevention of wash-out. In this contribution, the synthesis of magnetite nanoparticles by chemical coprecipitation is presented. In a first step, magnetite nanoparticles were prepared by coprecipitation of ****2+ and ****3+ with ammonium. Subsequently, magnetite nanoparticles were coated with a ligand shell consisting of Aminosilane. Different techniques were used for morphology and structure characterization. Dynamic light scattering technique was carried out to investigate the size distribution of nanoparticles in wet environment. TEM images also prove the formation of spherical MNP. For characterizing the crystal structure, X-ray diffraction was used. These measurements show that different parameters such as preparation speed have a significant influence on the size of nanoparticles.
