Photochemical Properties of Water-soluble Fluorinated Zinc Phthalocyanines and their Photocytotoxicity Against<font>HeLa</font>Cells

Abstract

Three types of amphiphilic water-soluble fluorinated zinc phthalocyanines are characterized. They have absorption bands at long wavelength, which cause greater penetration depth of a tissue. The uptake and photodynamic activity of the phthalocyanines against HeLa cells were measured, showing that the phthalocyanines exhibited higher photodynamic activities than zinc tetrasulfonated phthalocyanine.
