808 nm-activable core@multishell upconverting nanoparticles with enhanced stability for efficient photodynamic therapy

摘要

Illustration of the synthetic steps to produce UCNPs, their water transfer, and functionalization with two PSs (Rose Bengal and Chlorin e6). Intracellular location of UCNPs in endocytic compartments and PDT therapy induced by 808 nm laser irradiation, leading to the impairment of mitochondria
