我刚刚从与我一起工作的学生那里收到了以下内容，并想知道是否有人有任何建议？
"I have a silver nanoparticle solution that I’d like get a UV-Vis absorption spectrum for. However, I don’t know what else is in the solution (it’s a proprietary ink for 3D printing), but I suspect it’s a simple solvent + ligand + silver mixture. I could dry the solvent off and replace it with a known one, but I’m worried that might affect the silver nanoparticles too. I’m not sure what to do about the effect of the ligands. Do you have any advice for this situation?"
