SHG‐mediated drug release and cell damage. a) NIR light‐triggered drug release of Trp from functionalized BFO nanoparticles mediated by SHG process. b) Trp release profiles following irradiation of BFO nanoparticles conjugated with coumarin (CM) as photocleavable linker and Trp as a model molecular cargo (blue curve) with Ti:sapphire pulsed laser system at 790 nm.
