Chemical tuning of Coulomb blockade at room-temperature in ultra-small platinum nanoparticle self-assemblies

This work describes self-assemblies of ultra-small platinum nanoparticles, the electrical properties of which can be adjusted through slight modifications of the assemblies' constituents. Elaborating such systems, stable in air for months, is a first step towards nanoelectronic systems, where the charging energy of the nanoparticles is tuned by the nature of the ligands.
