Photodynamic therapy (PDT) has been applied in cancer treatment by utilizing reactive oxygen species to kill cancer cells. However, a high concentration of glutathione (GSH) is present in cancer cells and can consume reactive oxygen species. To address this problem, we report the development of a photosensitizer–MnO2 nanosystem for highly efficient PDT. In our design, MnO2 nanosheets adsorb photosensitizer...
Das Hexaazatrinaphthylen‐Radikalanion …… wurde als stabiles Kaliumsalz synthetisiert und in intakter Form an CoII koordiniert, wie R. A. Layfield et al. in der Zuschrift auf S. 5567 ff. beschreiben. Das Bild zeigt einen Kaliumkronenether als Fliegende Untertasse, die ein Elektron hinunter zum HAN‐Liganden in einem trimetallischen Cobalt(II)‐Komplex beamt. Die Reduktion des HAN‐Liganden verstärkt drastisch...
