Abstract
Photodynamic therapy (PDT) of cancer is a treatment with strengths and weaknesses. Amongst the latter is the need for the presence of oxygen for the photodynamic effect to occur. It is a known fact that singlet oxygen, generated from the first triplet excited state (T1) of the photosensitizer, is responsible for the lethal photodynamic effect [1, 2, 3, 4]. The problem lies in the lack of oxygen in the core of a tumor. It seems that the excited triplet state energy of the photosensitizers currently in use in PDT lies below the threshold of a lethal anoxic chemical reaction.
