I want to provide photoactivated disinfection into a periodontal pocket in the mouth using the beam of an LED red light with a 650nm wavelength.  Would a blue or dark  vegetable dye work as the photosynthesizer or would I have to use a traditional photosynthesizer  such as blue  tolonium chloride?
Thanks in advance for any help you can provide.

Did you mean "photo-sensitiser" rather than photosynthesiser?

yes a "photo-sensitiser".  I am looking at dyes such as Methylene blue.  I am curious to know if any dark pigmented solution such as a blue food coloring or a teeth disclosing solution would act in the same manner.
