In our study we determined the diffusion coefficient of Tween 20 micelles at different surfactant concentrations (10(-4)-10(-2) M) via fluorescence correlation spectroscopy. The hydrophobic fluorescent dye 9,10-bis(phenylethynyl)anthracene, located in the micellar phase, was used as marker for the diffusion of Tween 20 micelles. The hydrodynamic radius of the micelles, R(h), was estimated from the diffusion coefficient and compared with literature values from previous studies.
在我们的研究中，我们通过荧光相关光谱法测定了不同表面活性剂浓度（10⁻⁴ - 10⁻² M）下吐温20胶束的扩散系数。位于胶束相中的疏水性荧光染料9,10 - 双（苯乙炔基）蒽被用作吐温20胶束扩散的标记物。胶束的流体力学半径R(h)由扩散系数估算得出，并与先前研究的文献值进行了比较。
