제목 Facile synthesis of reduced graphene oxide-encapsulated metal and metal oxide nanoparticles
초록 Graphene-based hybrid composites have offered significantly improved performance for various applications including optoelectronic devices, biosensor devices, lithium ion batteries, catalyst and surface enhanced Raman spectroscopy substrates due to their unique properties such as good optical and electrical property and high specific surface area. Among them, the graphene/gold nanomaterial composites have been attractive attention in recent years because of their new optical, electrical, and catalytic properties. In this presentation, we present a simple approach for the fabrication of reduced graphene oxide-encapsulated gold , iron oxide, and titanium oxide nanoparticles using graphene oxide sheet-wrapping via electrostatic self-assembly. By mixing bovine serum albumin molecule-functionalized nanoparticles with graphene oxide dispersion, positively charged bovine serum albumin/nanoparticles easily assembled with negatively charged graphene oxide sheets through electrostatic interaction. Transmittance electron microscopy, scanning electron microscopy, atomic force microscopy, and Raman spectroscopy were used to confirm the encapsulation of graphene oxide on gold, iron oxide, and titanium nanoparticles.
