exosome外泌体粒径分析方法 | 三种技术比较 - 知乎
由于外泌体与材料学所合成的脂质体在形态上十分相似，因此用于脂质体表征的动态光散射技术（DLS）便被应用于外泌体的尺寸测量上。 DLS利用光射到远小于其波长的小颗粒上时会产生 …

DLS与TEM 测的粒径相差太大什么原因？ - 小木虫论坛
本人做的小分子纳米颗粒，测dls粒径在20nm左右，而透射电镜(TEM)下看到的是100nm左右。 两者相差太大是什么原因？ 冻干后测扫描电镜(SEM)得到的粒径在50nm左右。
Why was there size difference measured by TEM and DLS?
DLS weights the size distribution differently than TEM, i.e. it overerrates the larger particles due to their much stronger scattered light intensity (even if this overrating is probably a bit...
