Metallic composites based on Ag, Cu, Au and Ag-Cu nanoparticles with distinctive bactericidal effect on varied species

Because the spread of antimicrobial resistance is impacting current health, environmental, and technological developments, the synthesis of novel and efficient antibacterial agents is required. In this work, nanoparticles of Ag, Cu, Au and Ag-Cu were supported on TiO2 Degussa P25 by the deposition-precipitation with urea method (DPU). The antibacterial performance of these materials, well known as catalysts of reactions of environmental...
