Abstract
Photodynamic therapy (PDT) is the tripartite process that utilizes light, oxygen and photosensitizers, to produce reactive oxygen species (ROS) that can kill target cells. The main issues associated with conventional PDT are low selectivity, low levels of 1O2 production, dark toxicity and self-aggregation of photosensitizer. Photoimmunotherapy (PIT) is a novel type of molecular targeted t…
