However, accurate comparison of the efficacy of different organelle-targeted PDT approaches is challenging since it is difficult to find a single system that can achieve separate targeting of different organelles with separable time windows and similar binding amounts. Herein, we conjugated chlorin e6 (Ce6) with 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[amino(polyethylene glycol)-5000] (ammonium salt) (DSPE-PEG5000-NH2) to afford DSPE-PEG-Ce6, which could migrate from mitochondrion to lysosome and ultimately to endoplasmic reticulum (ER) after cellular internalization. Benefiting from the dynamic subcellular distribution of DSPE-PEG-Ce6 with tunable organelle-binding amounts, we accurately determined the PDT efficacy order of the molecule, i.e., mitochondrion > ER > lysosome. This work proposes an ideal model system for accurately evaluating the specific organelle-targeted PDT efficacy and may promote the future development of effective PDT strategies.
