Abstract
In this study we have found that cerium oxide nanoparticles exhibit catalase mimetic activity. Surprisingly, the catalase mimetic activity correlates with a reduced level of cerium in the +3 state, in contrast to the relationship between surface charge and superoxide scavenging properties.
摘要
在这项研究中，我们发现氧化铈纳米颗粒具有过氧化氢酶模拟活性。令人惊讶的是，过氧化氢酶模拟活性与三价铈的还原水平相关，这与表面电荷与超氧化物清除特性之间的关系相反。
