Abstract

The gold nanoparticles (GNPs) conjugation with magnetite nanoparticles is achieved in a two step process in which the initial step is a self-assembled monolayer of mercaptoundecanol on conjugation to GNPs by reducing HAuCl4 to obtain wine color suspension of hydroxyl capped GNPs, it is further proceeds to the reaction with phosphorus oxychloride and followed by hydrolysis, in which final step would be anchoring to magnetite nanoparticles by sonication. The nanometer sized core-shell hybrid materials having a GNPs core with ligand a shell conjugated magnetite nanoparticles in an ambient temperature, will be prepared in a facile synthetic manner. The grafting reaction is confirmed using ultraviolet-visible spectroscopy, X-ray diffraction, transmission electron spectroscopy and Infrared spectroscopy. This new approach of conjugating of two metal nanoparticles in a single linkage ligand will have fascinating approach in biomedical application.
