Solubility tests are essential for several reasons:
Bioavailability: In the context of drug delivery, the solubility of nanoparticles affects how well they can be absorbed by biological systems. Toxicity: The solubility of nanomaterials can influence their toxicity profiles. Insoluble nanoparticles may accumulate in organs, causing adverse effects. Functionalization: Soluble nanomaterials can be easily functionalized with various chemical groups to enhance their properties. Environmental Impact: Solubility tests help in understanding how nanomaterials behave in different environmental conditions, thereby assessing their potential ecological hazards.
