Tri-responsive porous silica carrier with gold nanoparticles for chemophotothermal combination therapy

A multifunctional nanoplatform (pSiO2–Au/HA) combining porous silica (pSiO2) carriers and gold nanoparticles (Au NPs) was synthesized for chemophotothermal synergistic therapy. The pSiO2 carrier has the diameter size of 70 nm and high specific surface area (510.8 m2·g−1). Au NPs as photothermal agents and gatekeepers were linked to pSiO2 carriers by Au–S bonds for redox-responsive drug release and photothermal effect. Hyaluronic acid (HA)...
