Researchers from Air Force Research Laboratory Report Details of New Studies and Findings in the Area of Gold Nanoparticles (Building 3D Layer-by-Layer Graphene-Gold Nanoparticle Hybrid Architecture with Tunable Interlayer Distance)

By a News Reporter-Staff News Editor at Life Science Weekly -- Researchers detail new data in Gold Nanoparticles. According to news reporting originating from Dayton, Ohio, by NewsRx correspondents, research stated, "The ability to construct self-assembled three-dimensional (3D) superstructures with desired functionality is not only of scientific curiosity but also crucial in the bottom-up nanofabrication of smart materials and devices."

Our news editors obtained a quote from the research from Air Force Research Laboratory, "Here a facile solution-processable strategy for creating 3D layer-by-layer graphene-gold nanoparticle architectures was developed in which cysteine molecules with amino groups were chemically grafted onto the surface of graphene oxide and then the cysteine thiol groups were attached to the surface of gold nanorods (GNRs) through strong covalent Au-S linkages. In this self-assembled structure, as revealed by transmission electron microscopy (TEM) and scanning electron microscope (SEM), it was confirmed that the graphene layers aligned in parallel fashion rather than randomly to each other by the lying down patterns of the GNRs, which also formed layers in parallel."

According to the news editors, the research concluded: "Furthermore, spherical gold nanoparticles with different sizes were used to control the interlayer distance of the 3D hybrid structure."
