I have nanomaterials composed of graphene and a drug. Can I perform CD? The pure drug that i used shows CD spectra. If so, what should be the sample preparation required? And what parameters I should be careful about... Any standard protocol applicable?
The spectrum of circular dichroism is shown only by optically active substances. You have material consisting of graphene and drug. The CD spectrum appears to be given by drug molecules. Usually they take the substance in a solvent, pour it into a cuvette and take a spectrum. Perhaps you have already received the spectrum, because The question was asked a long time ago. It would be interesting to know the composition of your material.
No, I haven't got a good spectrum. My material contains DNA and graphene. Pure DNA gives a spectrum. What about graphene and a mixture of graphene-dna? Is a good spectra expected? DNA is soluble but not graphene in any solvent.
DNA + graphene why? We compare the behavior of DNA + water with the behavior of surfactants + lutein + water. We believe that in both systems the water is coiled into a spiral using H-bonds. Look, maybe this will help solve your problem.
