We a did an experiment with Colloidal gold, in which we created gold Nano particles. Our teacher told us that we could detect that we had created nanoparticles by shining polarized light on it. We shined light on it from a 90 degrees angle and then we could not see the light on the other side of the glas as if something inside had stopped the light. Could you please exlpain to me why that proves we have created nanoparticles?
