Abstract
Micelles of cholesterol in aqueous solution have been investigated using polarized and depolarized dynamic light scattering. They are shown to be highly extended and characterized by a narrow size distribution. It is shown that a rod-like model is applicable with length, L = 580 nm. Determination of the rotational diffusion coefficient by analysis of the autocorrelation function gave a value of theta = 150 s-1, which is close to the calculated value for the rod with this dimension. Depolarized dynamic light scattering measurements as a function of angle gave a value of 110 s-1.
摘要
已使用偏振和去偏振动态光散射研究了胆固醇在水溶液中的胶束。结果表明，它们高度伸展且尺寸分布狭窄。研究表明，棒状模型适用，长度L = 580 nm。通过自相关函数分析确定的旋转扩散系数值为θ = 150 s-1，这与该尺寸棒的计算值相近。作为角度函数的去偏振动态光散射测量给出的值为110 s-1。
