Abstract

Cut here to cure: Doxorubicin attached to pH-sensitive mesoporous silica nanoparticles (MSN-hydrazone-Dox) shows potential in the chemotherapeutic treatment of liver cancer. Hydrolysis of the pH-sensitive hydrazone bond in the acidic environment of endosomes/lysosomes (see picture) releases Dox intracellularly from the MSN nanochannels, resulting in highly efficient apoptotic cell death.
