Values of SCLLs sizes and their polidispersity using photon correlation spectroscopy*
| Preparation | Mean size (nm) | P.I.** |
| SCLLs alone | 500.0 | 0.570 |
| SCLLs containig 5-ALA | 400.1 | 0.570 |
| (drug:lipids, 1:3) |
* Scattering angle of the laser beam was 90°; temperature 25°C, viscosity 0.890 and refraction index 1.33. **Polidispersity index, meaning the measurement of the homogeneity of a dispersion, ranging from 0.0 (monodisperse) to 1.0 (very heterogeneous).
