纳米技术有可能彻底改变我们的未来，但也引发了人们对纳米材料可能危害人类或生物圈的担忧。纳米颗粒的独特性质赋予它们新的尺寸依赖性功能，也可能造成伤害。现有人类健康和环境研究中的不确定性表明，高质量、充分表征的参比纳米材料对于毒理学研究非常重要。在这里，我们使用几种方法来说明纳米颗粒详细表征的重要性，特别是允许识别杂质和化学上相同但结构上不同的相。介绍了制备不同尺度的多壁碳纳米管的方法。
Nanotechnology has the potential to revolutionise our futures, but has also prompted concerns about the possibility that nanomaterials may harm humans or the biosphere. The unique properties of nanoparticles, that give them novel size dependent functionalities, may also have the potential to cause harm. Discrepancies in existing human health and environmental studies have shown the importance of good quality, well-characterized reference nanomaterials for toxicological studies. Here we make a case for the importance of the detailed characterization of nanoparticles, using several methods, particularly to allow the recognition of impurities and the presence of chemically identical but structurally distinct phases. Methods to characterise fully, commercially available multi-wall carbon nanotubes at different scales, are presented.
