Photosensitizer-Laden Neutrophils Are Controlled Remotely for Cancer Immunotherapy
Summary: By incorporating an artificial reactive oxygen species (ROS) generation mechanism, a biotic/abiotic integration is designed to improve the anti-tumor effect of neutrophils by artificially potentiating their ROS effector mechanism in a remotely controlled route. Specifically, the photosensit...
