Synthesis of Luminescent Ag Nanoclusters with Antibacterial Activity

This paper focuses on the synthesis of novel Ag nanoclusters (NCs) using DHLA as capping reagents in aqueous solution by a photoreduction method. Luminescence studies indicated that the DHLA-Ag NCs exhibited strong blue emission with maximum peak at 480 nm. The maximum emission of the NCs can be gre...

Summary:This paper focuses on the synthesis of novel Ag nanoclusters (NCs) using DHLA as capping reagents in aqueous solution by a photoreduction method. Luminescence studies indicated that the DHLA-Ag NCs exhibited strong blue emission with maximum peak at 480 nm. The maximum emission of the NCs can be greatly improved with irradiating time by around 15-fold from 3 h to 67 h. By means of mycelium growth rate, the results showed that the Ag NCs with smaller sizes had a good antimicrobial effect.
