Abstract

Novel ternary complexes formed from plasmid DNA, cationic peptides and anionic dendrimer photosensitizers were newly developed for the light-directed transfection. In this study, the atomic force microscopic (AFM) observation has revealed that the ternary complexes possessing optimal compositions had a spherical shape with the diameter of approximately 150nm and a narrow size distribution, and the in vitro biological studies have demonstrated that such ternary complexes showed the efficient light-induced transfection while showing little photocytotoxicity and cytotoxicity after a prolonged incubation. Thus, the ternary complexes are expected to be a promising non-viral vector for site-directed transfection in vivo.
