Working with silica nanoparticle encapsulated BODIPY and xanthene photosensitizers, we have determined that singlet oxygen spends up to 78% of its lifetime inside the nanocarriers. Our systematic investigation indicates that hydrophobicity rules the photosensitizer distribution in nanoparticles, which in turn dictates the ability of these structures to release singlet oxygen.
