Glutathione-Sensitive Mesoporous Organosilica-Coated Gold Nanorods as Drug Delivery System for Photothermal Therapy-Enhanced Precise Chemotherapy.

ABSTRACT: The combination of photothermal therapy (PTT) and chemotherapy can remarkably improve the permeability of the cell membrane and reduce the concentration of chemotherapy agents that not only kill the tumor cells effectively but also have adverse effects on normal tissues. It is of great meaning to construct nanomaterials that could be simultaneously applied for tumor eradication with PTT and chemotherapy. In this work, we developed a novel gold nanorod coated with mesoporous organosilica nanoparticles (oMSN-GNR), which presented as an optimal photothermal contrast agent. Moreover, after doxorubicin loading (oMSN-GNR-DOX), the organosilica shell exhibited biodegradable properties under high glutathione in the tumor microenvironment, resulting in massively releasing doxorubicin to kill tumor
