Zinc-substituted myoglobin (ZnMb) is a naturally occurring photosensitizer that generates singlet oxygen with a high quantum yield. Using a combination of photophysical and fluorescence imaging techniques, we demonstrate the interaction of ZnMb with Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli. An efficient...

Bioavailability of photosensitizers for cancer photodynamic therapy is often hampered by their low solubility in water. Here, we overcome this issue by using the water-soluble protein apomyoglobin (apoMb) as a carrier for the photosensitizer hypericin (Hyp). The Hyp-apoMb complex is quickly uptaken by HeLa and PC3 cells at submicromolar...
