Synthesis of AuNC stabilized by F27SH and crystallization of [Au25(SF27)18]0. a Cartoon representation of AuNC stabilized by F27SH thiol. For the sake of clarity, only 6 F27S-ligands have been reported; b schematic representation of crystal formation in solkane solution and colorimetric change upon their dissolution in PFO; c UV–Vis spectra of crude product in solkane and crystals redissolved in PFO; d, e STEM images of crude product showing the presence of small clusters and bigger AuNPs; f, g STEM images of redissolved crystals solution showing the homogeneous presence of small clusters.

The SupraBioNano Lab (SBNLab)at the Politecnico di Milano's Department of Chemistry, Materials and Chemical Engineering "Giulio Natta," in partnership with the University of Bologna and the Aalto University of Helsinki (Finland) has, for the first time, synthesized a superfluorinated gold nanocluster, made up of a core of only 25 gold atoms, to which 18 branch-structured fluorinated molecules are linked. The project was recently published in Nature Communications.
The metal clusters are an innovative class of very complex nanomaterial, characterized by ultra-small dimensions (
