|a Exploring polymeric nanoplatforms combined with reactive oxygen species (ROS) responsiveness with mitochondria targeting has emerged as an effective strategy for enhanced photodynamic therapy (PDT). Amphiphilic copolymers were synthesized by reacting acrylamide thioketal (TK) linkers with amino-terminated triphenylphosphonium-polyethylene glycol and dodecylamine for encapsulating chlorin e6 (Ce6) via self-assembly. Then, anionic cladding with tumor targeting deshelled in tumor acidic microenvironments was surface-anchored by electrostatic forces (BioPEGDMARM). After sequential targeting to the mitochondria of cancerous cells, BioPEGDMA@RM could be light-activated with Ce6 released upon ROS cleavage of TK linkages. It was found that Ce6-loaded BioPEGDMA@RM exhibited higher cytotoxicity on CT26 cells and performed stronger ability on the production of ROS than that without TK linkers. Moreover, a minimum illumination of 3 and 5 min could be required for achieving the maximum release of Ce6 and high in vitro cytotoxicity for Ce6-loaded BioPEGDMA@RM, respectively. Furthermore, Ce6-loaded BioPEGDMA@RM showed 1.29-fold and 1.21-fold higher tumor inhibition on BALB/c nude mice and Kunming mice and stimulated immunologic reactions with more generation of IFN-γ and TNF-α and activation of CD3+, CD4+, and CD8+ T-lymphocytes and DCs than that of Ce6-loaded nanoparticles without TK bonds. This work provided an academic reference for the development of ROS-responsive drug delivery systems for advanced PDT efficiency
