Antibacterial activity of ZnO-CeO2 solid nano-powders was studied by measuring the change of sterilization efficacy to the bacterial. ZnO-CeO2 nano-powders were prepared by laser vapor condensation (LVC) with oxygen as loading gas. The size of the particle can be affected greatly by some reacting conditions such as the flow of loading gas and the reacting pressure. Rod-like powders with different molar ratios (Zn/Ce) and sizes were produced in the changed reacting conditions for studying the effects of sterilization efficacy to the bacterial. It is found that antibacterial activity of oxide powders increase with decreasing particle size and increasing ceria concentration. The changes of antibacterial action for S. aureus are similar to those for B.niger. Both the preparing mechanism of LVC and the sterilization assumption were proposed. 展开更多
