Measuring amount of c60 fullerenes dissolved in oil

May 2019
Hello All,

Please forgive my ignorance. I really don't know much about chemistry. I have been searching the web for the answer to my question, but I haven't been able to find anything that I can understand/use. I have been dissolving c60 fullerenes in various types of oil for a while now. I would really like to find a way to measure the amount of fullerenes that have actually been dissolved in the oil after stirring. I have been looking at spectrophotometers, but don't know how to use that data to achieve my goal. It would seem that some data regarding the light related properties of the fullerenes, minus the oil would be needed. Would someone be so kind as to give me some guidance on how I might make this measurement and what equipment would be necessary?

Thanks for your consideration,
