英文摘要Due to the unique physical and chemical properties, nanosized cerium oxide (n-CeO(2)) has attracted considerable interest in many fields of research. The potential, the growing use and the mass production of n-CeO(2) have stimulated research on their potential impact on the environment and human health. However, the toxicological definition for CeO(2) nanoparticles (NPs) is still quite controversial. In the present work, we evaluated the antibacterial activity of CeO(2) NPs sized ca. 7 nm (7-CeO(2)), ca. 25 nm (25-CeO(2)) and their bulk counterpart (b-CeO(2)), using gram-negative Escherichia coli (E. coli). Our results suggest that all the three types of CeO(2) particles have antibacterial activity, and both the NPs are more toxic than b-CeO(2). The rise in intracellular ROS level induced by direct contact of particles with the surface of E. coli was involved in the mechanism for the antibacterial activity of CeO(2) NPs. Exposure to 25-CeO(2) could also impair the integrity of the outer membrane within E. coli cells. Due to agglomeration and negligible effect on membrane integrity, 7-CeO(2) did riot exhibit greater antibacterial activity than 25-CeO(2).
