Nanosized mesoporous metal-organic framework MIL-101 as a nanocarrier for photoactive hexamolybdenum cluster compounds

Hexamolybdenum clusters possessing red fluorescence were introduced into nanosized chromium terephthalate metal-organic framework. Clusters anchored via pyrazine cannot penetrate into cells whereas clusters from pyrazine-free compound transport through membrane and generate singlet oxygen in cancer Hep-2 cells. Thus, such system is a suitable nanocarrier for applications in photodynamic therapy.407
