Solubility can be measured using various techniques:
1. Dynamic Light Scattering (DLS): Used to determine the size distribution of nanoparticles in a solution, providing indirect information about their solubility. 2. UV-Vis Spectroscopy: Measures the absorbance of nanoparticles in a solution, which can be correlated to their concentration and solubility. 3. High-Performance Liquid Chromatography (HPLC): Separates and quantifies nanoparticles in a solution, offering precise solubility measurements.
