Paper Abstract

Tetrasulphonated aluminum phthalocyanine (AlPcS4) is one of the extensively studied second generation sensitizers for photodynamic therapy of cancer. We've applied picosecond fluorescence spectroscopy to study the fluorescence decay lifetimes of AlPcS4 in phosphate buffer at different pH values and in monolayers of cultured cells incubated in photosensitizer solution. The decay time for the cells in the buffer is closer to the one obtained for acidic aqueous solution indicating that at least part of the phthalocyanine could be found in the acidic microenvironment (lysosomes, etc.).
