Accurate characterization of particle size and particle size distributions is mandatory in nanotechnology and a broad range of colloidal sciences. The size of colloidal particles can be determined using various techniques in direct and reciprocal space, including electron microscopy and static and dynamic light scattering. Differential dynamic microscopy was introduced recently and offers a new alternative. In this paper we present a systematic study of particle size determination using various techniques. We compare the results and highlight advantages and disadvantages. Unexpectedly we find that differential dynamic microscopy offers the unique possibility to determine the particle size in highly turbid samples.
在纳米技术和广泛的胶体科学领域，准确表征粒径和粒径分布是必不可少的。可以使用直接和倒易空间中的各种技术来确定胶体颗粒的大小，包括电子显微镜以及静态和动态光散射。差分动态显微镜是最近引入的，提供了一种新的选择。在本文中，我们对使用各种技术测定粒径进行了系统研究。我们比较了结果并突出了优缺点。出乎意料的是，我们发现差分动态显微镜提供了在高浊度样品中测定粒径的独特可能性。
