NIR light-triggered drug delivery system using core-shell gold nanostars-mesoporous silica nanoparticles by multiphoton absorption photo-dissociation of 2-nitrobenzyl PEG

Gold nanostars coated with a mesoporous silica shell and functionalized with poly(ethylene glycol) containing photolabile 2-nitrobenzyl moieties are able to release doxorubicin after NIR light irradiation at low power irradiance via a multiphoton absorption photo-dissociation process.
