The variability observed here was not atypically large, but serves to illustrate the difficulty inherent in predicting the outcome of PDT treatments based on administered light and photosensitiser dose alone.
Rather than administering excitation light, bioluminescence imaging based on firefly luciferase (luc) requires introduction of the enzyme substrate luciferin that reaches target areas via the blood supply and diffusion.
This experimental technique involves administering a light-absorbing substance that is selectively retained by the tumour cells.

Manual lymphatic drainage (MLD), a form of massage, is administered using light strokes to direct lymph flow from blocked to open lymphatics [ 5- 7].
