Synthesis of Luminescent Ag Nanoclusters with Antibacterial Activity

Figure 5

Antibacterial ability of Ag NCs. Photographs were taken after incubation for 5d at 20°C. (a), (b), and (c) represent Ag-DHLA complex, 2 nm Ag NCs, and 200 nm Ag NCs, respectively; (d) represents water (control). The inhibition rates of (a), (b), and (c) against wheat phytoalexin were 15.47%, 25.46%, and 49.64%, respectively. The concentration of Ag-DHLA complex was 62.5 μM.
