在这里，我们提供了一个完整的审查使用动态光散射（DLS）研究磁性纳米粒子（MNP）的尺寸分布和胶体稳定性。介绍了从相关函数中获取尺寸信息的数学分析和Z平均值的计算。各种变量的贡献，如表面涂层，尺寸差异，和颗粒的浓度，阐述了测量数据的范围内。与其他尺寸测量技术，如透射电子显微镜和暗场显微镜的比较，揭示了DLS在测量磁性纳米颗粒尺寸方面的优点和缺点。DLS还可以有效地监测具有各向异性结构的MNP的自组装过程。
Here we provide a complete review on the use of dynamic light scattering (DLS) to study the size distribution and colloidal stability of magnetic nanoparticles (MNPs). The mathematical analysis involved in obtaining size information from the correlation function and the calculation of Z-average are introduced. Contributions from various variables, such as surface coating, size differences, and concentration of particles, are elaborated within the context of measurement data. Comparison with other sizing techniques, such as transmission electron microscopy and dark-field microscopy, revealed both the advantages and disadvantages of DLS in measuring the size of magnetic nanoparticles. The self-assembly process of MNP with anisotropic structure can also be monitored effectively by DLS.
