A drop of colloïdal solution of Gold nanoparticles (diameter 2nm), passivated by thiol molecules C8H17S (total diameter around 3nm) [Brust et al., J. Chem. Soc., Chem. Commun. (1994)]in dichloromethane is deposited on the Surf (no pretreatment of the surface by O3). The solvent is evaporated at RT. Viscoelastic fracture in thick film of nanoparticles (fracture reminiscent of that observed with certain kind of polymer films).
