Plasmon-Assisted Production of Reactive Oxygen Species by Single Gold Nanorods

The generation of reactive oxygen species by gold nanorods under ultrashort‐pulsed irradiation is investigated at the single‐nanoparticle level. Near‐infrared femtosecond pulses induce the production of hydroxyl radicals in a hydrogel medium through a plasmon‐assisted, polarization‐controlled, multi...

Zusammenfassung:	The generation of reactive oxygen species by gold nanorods under ultrashort‐pulsed irradiation is investigated at the single‐nanoparticle level. Near‐infrared femtosecond pulses induce the production of hydroxyl radicals in a hydrogel medium through a plasmon‐assisted, polarization‐controlled, multiphoton process. Three‐photon luminescence is also observed, allowing a potential replacement for photodynamic agents combined with nonlinear imaging properties.
