Photophysics and photochemistry of zinc phthalocyanine/bovine serum albumin adducts
Abstract
Zinc phthalocyanine (ZnPc) is a well known Type II (singlet oxygen mediated) hydrophobic photosensitizer with potential use in PDT. We have found that the presence of bovine serum albumin diminishes the aggregation degree of ZnPc in aqueous solution, indicating that albumins could be potentially useful carriers for this type of photosensitizer in PDT. In order to explore the photochemical and photophysical behavior of ZnPc associated to the
