In the current work, we have processed a serial dilution of Aurum Met (gold nanoparticle colloidal) by a conventional method. We have chosen different tools (spectroscopy and microscopy) to understand the effect of serial dilution and succussions. Spectroscopy measurement shows that the solution contains Au nanoparticles with different size distributions. Electron microscopy has been used to confirm the presence of Au NPs in different morphology and size.
