Abstract

Surface characteristics of gold nanoparticles [1] at ambient conditions and in vacuum of the order of 10-4 Pa are compared using Atomic Force Microscopy topographic images in tapping mode. The results show the improvements of the images got at lower pressure than that obtained to normal laboratory conditions. The image got at lower pressure shows more clearly the like spheroid shape characteristics of the particles as predicted by the SPR experiments and theory [1]. Profiles and RMS roughness of the particles are also measured.
