Phototriggered Self‐Adaptive Functionalized MOC‐Based Drug Delivery Platform Promises High Antitumor Efficacy

Due to their great stability and special cavities, metal‐organic cages (MOCs) are increasingly considered as promising nanocarriers for drug delivery. However, the size and surface dilemmas restrict their further biomedical applications. The ultrasmall size of MOCs facilitates tumor penetration but suffers from quick clearance and poor accumulation at the tumor site. Hydrophobicity of MOC surfaces improves internalization into tumor cells while...
