Silver Clusters - Invisible Worlds

Silver clusters deposited by thermal evaporation onto self-assembled polystyrene nano-spheres (900 nm). Inspect F SEM FEG @ Nanofacility Piemonte INRIM. Self-assembled polystyrene nanospheres are used as masks for thin films and materials nanostructuration on large area. Maybe the subject doesn't match the topics of this year, but surely the title fits.

Gold Mushroom

Gold Nanorods are electrochemically grown to produce SERS active surfaces. Each rod has a diameter of approximately 200nm, however, the length is dependent on the deposition time. If the deposition time is too long, then rods become longer than the template. Without site directed growth, the gold forms larger aggregates, which resulted in the formation of the gold mushroom after the template was removed.
