True-that....only catch is that the lengthy FDA approval process would come into play for anything internal. To speed this process up, I wonder if QDots could be made directly out of a powdered form of the (already approved) drugs themselves[?]...then attach a few key proteins to guide it to the target cells.
On a semi-related note; I see some promise with incorporating QDots into external realtime tricorder diagnostics apps, like this cancer diagnostic pen http://www.bbc.com/news/health-41162994 , which seems closely akin to this QDot Spectrometry tech: https://investorshangout.com/post/view?id=4723153
