Relieving tumor hypoxia. (A) An in situ photocatalyzed oxygen generation system is developed by conjugating ICG-encapsulated human serum albumin nanoparticles onto Synechococcus (S/HAS/ICG). The platform preferentially accumulates in tumors, and laser-triggered oxygen generation promotes ROS production to enhance photodynamic efficacy and antitumor immunity.
