The antibacterial spectrum of the nanoscale TiO2-Pt photocatalyst.

The survival rate of various bacteria after challenged with TiO2-Pt-mediated photocatalysis. The visible light-driven antibacterial activity of TiO2-Pt-mediated photocatalysis against various bacteria is shown; the soil-borne pathogens B. pseudomallei and B. cenocepacia were compared with nonpathogenic E. coli OP50 and the pathogenic bacteria S. aureus, A. baumannii, L. pneumophila, P. aeruginosa, K. pneumoniae and S. typhimurium. The untreated groups (without TiO2-Pt and illumination) of each experiment were normalized to 100%. n = 6, three experiments with 2 replicates).本数据集记录了各类细菌经二氧化钛-铂（TiO₂-Pt）介导光催化处理后的存活率。本研究展示了TiO₂-Pt介导的可见光驱动光催化抗菌活性：以土传病原菌类鼻疽伯克霍尔德菌（Burkholderia pseudomallei, B. pseudomallei）、洋葱伯克霍尔德菌（Burkholderia cenocepacia, B. cenocepacia）与非致病性大肠杆菌OP50（Escherichia coli OP50）为对照，同时纳入致病性细菌金黄色葡萄球菌（Staphylococcus aureus, S. aureus）、鲍曼不动杆菌（Acinetobacter baumannii, A. baumannii）、嗜肺军团菌（Legionella pneumophila, L. pneumophila）、铜绿假单胞菌（Pseudomonas aeruginosa, P. aeruginosa）、肺炎克雷伯菌（Klebsiella pneumoniae, K. pneumoniae）及鼠伤寒沙门氏菌（Salmonella typhimurium, S. typhimurium）进行比较。所有实验的未处理组（未添加TiO₂-Pt且无光照）均归一化至100%。实验总重复数为n=6，共开展3次独立实验，每次实验设置2个重复样本。
