T. G. Schaaff,Marat N. Shafigullin,Joseph T. Khoury,Igor Vezmar,Robert L. Whetten,William G. Cullen,Phillip N. First,Gutierrez-Wing C,J. Ascensio,Miguel Jose-Yacaman +9 more
TL;DR: In this article, five massive gold-cluster molecules have been isolated in high yield and have undergone separate structural characterization, and their electronic structure has been deduced by optical absorption spectroscopy.

Surface diffusion and coalescence of mobile metal nanoparticles.
TL;DR: It is demonstrated that the liquid-like properties of the surface layers of the nanoparticles play an essential role in this process, based on the high-resolution electron microscopic analysis of several different types of nanoparticles.

Noble-metal nanoparticles directly conjugated to globular proteins.
TL;DR: This synthesis method is a new technique for directly attaching gold nanoparticles to macromolecular proteins and demonstrates that the disulfide bonds in the conjugated protein are broken and thus are available for interaction with the nanoparticle surface.

TL;DR: The combination of these experimental techniques with calculated UV-vis absorption spectra allowed the elucidation of the nanoparticles structure and elemental distribution, and their results support the idea of a Pt(core)-Au(shell) structure with the elements segregated from each other.

HAADF study of Au-Pt core-shell bimetallic nanoparticles
TL;DR: In this paper, a High Angle Annular Dark Field (HAADF) technique was proposed to identify core-shell structures in nanoparticle systems, based on the orientation of the particle with respect to the electron beam.
