Phototoxicity (red open symbols) and dark-toxicity (black solid symbols) of (A) 0.2% PpIX-micelles and (B) 4% PpIX-micelles as a function of micelle/PpIX dose after 24 hr incubation. The relative survival were normalized to the control cells without light nor PpIX. Both PpIX-encapsulated and PpIX-conjugated formulations were shown in each figure. Laser irradiation conditions were: λ = 532 nm, power density = 20 mW/cm2, total light dose = 12 J/cm2.
