A simple technique to fiddle with silver atoms

Organic ions or molecules that bind to the surface of noble metal nanoclusters are known as ligands. Usually, these ligands are modified to allow for tailoring the nanoclusters leading to potential practical applications.

So far, however, it has not been well understood how modifying the ligand alters the electronic and optical properties of the metal nanoclusters.

In a new study published in Inorganic Chemistry1, scientists from Saudi Arabia and the US demonstrate how surface-bound mercaptonitrobenzoic acid molecules can alter the electronic and optical properties of silver nanoclusters.

They were able to induce such change by tweaking the pH chemistry of such systems.read more
