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.
我们使用被二氧化硅纳米颗粒包裹的 BODIPY 和呫吨类光敏剂进行研究，确定了单线态氧在纳米载体中的寿命长达 78%。我们的系统研究表明，疏水性决定了光敏剂在纳米颗粒中的分布，进而决定了这些结构释放单线态氧的能力。
