Janus Gold Nanostars–Mesoporous Silica Nanoparticles for NIR‐Light‐Triggered Drug Delivery

Janus gold nanostar–mesoporous silica nanoparticle ( AuNSt–MSNP ) nanodevices able to release an entrapped payload upon irradiation with near infrared (NIR) light were prepared and characterized. The AuNSt surface was functionalized with a thiolated photolabile molecule ( 5 ), whereas the mesoporous silica face was loaded with a model drug (doxorubicin) and capped with proton‐responsive benzimidazole‐β‐cyclodextrin supramolecular gatekeepers ( N...
