Fullerene-C60, a representative of carbon nanocompounds, is suggested to be promising agent for application in photodynamic therapy due to its unique physicochemical properties. Fullerene-C60 probes the intramolecular dynamics of its electron and energy transfer[1].
High affinity of fullerene core for electron donors determines its ability to be a scavenger of free radicals. On the other hand, C60 molecule is able to absorb effectively UV and visible light with further transition to the first singlet excited state, then to a long-lived triplet excited state and subsequent energy transfer to molecular oxygen-yielding singlet oxygen with quantum yield close to 100%[1].
