An arginyl‐glycyl‐aspartic acid peptide‐modified carboline ruthenium complex KS‐Ru self‐assembled in a pH‐sensitive manner. It entered the lysosomes and formed nanoflowers, leading to lysosomal swelling. In addition, it entered the nucleus to damage DNA, inducing immunogenic cell death. Thus, it realized a dual impact on tumor growth and metastasis through synergistic chemotherapy and immunogenic...

Hydroxyl radical (•OH) with strong oxidation capability is one of the most important reactive oxygen species. The generation of •OH from superoxide radicals (•O2−) is an important process in visible‐light‐driven photocatalysis, but the conversion generally suffers from slow reaction kinetics. Here, a hydrophobicity promoted efficient •OH generation in a visible‐light‐driven semiconductor‐mediated...
