本研究以十二烷基硫酸钠（SDS）和聚乙烯吡咯烷酮（PVP）为稳定剂，制备了银纳米粒子（Ag-NPs）和铂纳米粒子（Pt-NPs）水溶液，研究了它们对金黄色葡萄球菌（S.金黄色葡萄球菌）和大肠杆菌（E. coli）的最低抑菌浓度（MIC）。银纳米粒子对沙门氏菌的抑菌效果金黄色葡萄球菌和大肠埃希菌进行了研究，采用杯扩散法。革兰氏阳性（S. aureus）和革兰氏阴性（E. coli）细菌的抑菌活性。Ag-NPs对S. aureus和E.大肠杆菌的最低浓度分别为5和10 ppm。但用SDS稳定的Au-NPs没有显示出抗菌活性。此外，用PVP（或SDS）稳定的Pt-NP未显示出对测试生物体的抗微生物活性。(C)2005爱思唯尔有限公司保留所有权利。
In this study, we investigated the antimicrobial activity of silver nanoparticles (Ag-NPs) and platinum nanoparticles (Pt-NPs) aqueous solution, which were prepared using different stabilizer, such as sodium dodecylsulfate (SDS) and poly-(N-vinyl-2-pyrrolidone) (PVP), for Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) by measuring the minimum inhibitory concentration (MIC). Antimicrobial effect of Ag-NPs for S. aureus and E coli was investigated using cup diffusion method. The growth of Gram-positive (S. aureus) and Gram-negative (E. coli) bacteria were inhibited by Ag-NPs. The MIC of Ag-NPs for S. aureus and E. coli were 5 and 10 ppm, respectively. But the Au-NPs stabilized with SDS did not show antimicrobial activity. Also, the Pt-NPs stabilized with PVP (or SDS) did not show antimicrobial activity for the test organisms.
