SpletPhotosensitizers are light absorbers that alters the course of a photochemical reaction. They usually are catalysts. [1] They can function by many mechanisms, sometimes they donate an electron to the substrate, sometimes they abstract a hydrogen atom from the substrate. At the end of this process, the photosensitizer returns to its ground state ... SpletPhotochemical internalization (PCI) is a novel technology for release of endocytosed macromolecules into the cytosol. The technology is based on the use of photosensitizers located in endocytic vesicles.

SpletIn said study, UCNPs were co-loaded with TPPS2a (PSs) and photo-morpholino (anti-STAT3, nucleic analogous for gene knockdown). 141 Under NIR excitation, TPPS2a was triggered by UCNP to generate ROS to locally disrupt the endosomal vesicle walls and trigger the release of the particles. SpletPCI of saporin was performed on endothelial human umbilical vein endothelial cell (HUVEC) and fibrosarcoma cells (HT1080) using two PCI-relevant photosensitizers, TPPS2a and …
