title = "Single-step laser ablation synthesis of ZnO–Ag nanocomposites for broad-spectrum dye photodegradation and bacterial photoinactivation",
abstract = "We present the single-step production of zinc oxide (ZnO)–silver (Ag) nanocomposites using a second harmonic nanosecond laser. The Ag concentration was controlled using various concentration of AgNO3 solution as the medium. The evaluation of the structural and optical characteristics indicated the formation of ZnO–Ag nanocomposites. The resulting nanocomposites exhibited photocatalytic activity in broad-spectrum light, both UV and visible light, for the degradation of rhodamine 6G. Furthermore, the nanocomposites were assessed as antibacterial agents, and the addition of Ag improved the antibacterial activity of pure ZnO against Escherichia coli and Staphylococcus aureus. Under light exposure, Ag greatly increased S. aureus degradation through a simultaneous antibacterial process. Eventually, the nanocomposites could be anticipated as photoactivation antibacterial agent and water purification nanocatalyst applications.",
