Hybrid nanostructures with enhanced optical and magnetic properties

Abstract

This is an experimental work where synthesis of both magnetite and gold nanoparticles (NPs) have been performed in the laboratory, obtaining gold NPs with a diameter of 4 nm and magnetite NPs of 8 nm. Afterwards, these NPs were protected following two different methods. First, a silica coating was tried, while the second method was performed with 11-mercaptoundecanoic acid (MUA) both aiming at building a hybrid nanostructure combining both NPs. Finally, to determine the quality and characterization of the resultant nanostructures, several measurements have been done, such as transmission electron microscopy, thermogravimetry, hysteresis loops and absorbance
