photodynamic

activated or made more powerful by light.

photodynamic agent
a substance that is activated by light to cause damage to tissue. It may be exogenous and absorbed preformed from the environment, or endogenous in that it is formed within the body as an abnormal metabolite, e.g. porphyrins, or as a normal metabolite, e.g. phylloerythrin, and accumulate in tissues because of faulty excretion, e.g. in hepatic disease.
photodynamic therapy
the use of photodynamic agents in the treatment of disease.

Novel strategies in PDT have been developed over the past several decades, including the development of nanomaterial-based platforms for selective photosensitizer delivery or light source and optic catheters for increased tissue penetration at longer wavelengths [15, 16], whereas, focusing on improving direct cytotoxicity to tumor cells through various techniques, vascular-targeted photodynamic therapy takes advantage of intravascular excitation of a photosensitizer to produce cytotoxic ROS that could induce vascular damage including local thrombus formation, vascular occlusion, and tissue hypoxia [17, 18].
