A simple approach for glutathione functionalized persistent luminescence nanoparticles as versatile platforms for multiple in vivo applications.

We develop a simple method by constructing glutathione (GSH) conjugated persistent luminescence nanoparticles (PLNPs-GSH) as versatile platforms for multiple biological applications. PLNPs-GSH possess enhanced water solubility and contains a large number of active groups, which offer opportunities for further modification with different functional groups.
