使用几种最先进的分析技术（透射电子显微镜、原子力显微镜、动态光散射、荧光相关光谱、纳米颗粒跟踪分析、流场流分馏）来确定稳定（24 h）纳米颗粒悬浮液的大小。评价了理论和分析方面的考虑，比较了结果，并讨论了这些技术的优点和局限性。由于每种技术都有其自身的优点和局限性，因此没有发现在环境背景下表征人造纳米颗粒的“理想”技术。
Sizes of stabilized (24 h) nanoparticle suspensions were determined using several state-of-the-art analytical techniques (transmission electron microscopy; atomic force microscopy; dynamic light scattering; fluorescence correlation spectroscopy; nanoparticle tracking analysis; flow field flow fractionation). Theoretical and analytical considerations were evaluated, results were compared, and the advantages and limitations of the techniques were discussed. No "ideal" technique was found for characterizing manufactured nanoparticles in an environmental context as each technique had its own advantages and limitations,
