“…Recent synthetic innovations have allowed the fabrication of atomically precise metal nanoclusters (NCs). [8][9][10][11][12][13][14][15][16][17][18] These metal NCs contain a few to hundreds of metal atoms that are protected by organic ligands (e.g., thiolate, phosphine, small molecules, synthetic polymers, and biomolecules). Particularly, thiolate-protected metal NCs and their alloy NCs can be prepared with atomic precision as M n (SR) m (M ¼ gold (Au), silver (Ag), cupper (Cu), platinum (Pt), palladium (Pd), or other element; SR ¼ thiolate ligand) in a wide range of sizes by varying the n and m values.…”
