Mesoporous silica nanocarriers (MSNs) are appealing in terms of their large cavity surface area and high loading capacity, but they have been suffering from premature cargo release. Herein, we report a gated smart MSN that is sensitive to low oxygen concentration (i.e., hypoxia) via taking advantage

Radiation dosage constraints and hypoxia-associated resistance lead to the failure of radiotherapy (RT), especially in hypoxic liver cancer. Therefore, the intricate use of combined strategies for potentiating and complementing RT is especially important. In this work, we fabricated multifunctional
pH/hypoxia programmable triggered cancer photo-chemotherapy based on a semiconducting polymer dot hybridized mesoporous silica framework.
