A PET-activated photosensitizer based on ROS-sensitive Trolox for tumor microenvironment-responsive imaging and therapy
{{output}}
We designed a dormant photosensitizer, EtNBS-2C-Tro, featuring a Trolox-modified benzo[a]phenoxazinium scaffold for ROS-responsive activation. In normal cells, both fluorescence and photodynamic therapy effects are effectively quenched via photoinduced electro... ...
