In this paper, the synthesis of gold@gold(I)
thiolate core@shell nanoparticles is described for the first time. The chemical nature and structure of these nanoparticles were characterized by a multi-technique approach. The prepared particles consist of gold metallic cores, about 1 nm in size, surrounded by stable gold(I)
thiomalate shells (Au@Au(I)
TM). These nanoparticles could be useful in medicine due to the interesting properties that gold(I)
thiomalate has against rheumatoid arthritis. Furthermore, the described results give new insights in the synthesis and characterization of metallic and core@shell nanoparticles.
