A drop of colloïdal solution of Gold nanoparticles (diameter 2nm), passivated by thiol molecules C10H21S (total diameter around 3nm) [Brust et al., J. Chem. Soc., Chem. Commun. (1994)]in dichloromethane is deposited in the centre of a Teflon ring [Pauliac-Vaujour et al., J. Phys. Chem. C (2007)] on the Surf (pretreatment of the surface by O3). The solvent is evaporated at RT. 3D image of a common arrangement for a high concentration of nanoparticles. Cellular networks on several levels with several different characteristic length scales. Presence of a pattern probably linked to the evaporation and hydrodynamic flow in the solvent (close to the Teflon ring). |
