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.

Bacteriophage T4 Virus

False-coloured image of T4 bacteriophage incubated with a de novo-designed self assembling peptide fibre (SAF). Small peptides, 28 amino acids long, self assemble to form fibres ~80 nm wide and ~40 microns long. The T4 tail striation distance was being used as a high-resolution calibrant to register the lateral striations of the fibre.
