RESUMO

The self-aggregation of pheophytin, a possible photosensitizer for Photodynamic Therapy, is solved by formulation in polymeric surfactant as P-123. The photosensitizer incorporation was found to be time dependent, exhibiting two steps: a partition at the micellar interface followed by an incorporation into the micelle core. The photodynamic efficiency of the formulation was tested by the bioassays against Artemia salina. In order to evaluate how the experimental parameters: pheophytin concentration, P-123 percentage and illumination time influenced the death of artemia, the factorial design 2³ was chosen. The illumination time was found to be the main factor contributing to the mortality of artemia.
