Abstract

Synthetic vectors have been considered as a safer and more versatile alternative to viral-based gene delivery systems. A variety of simple synthetic vector systems such as cationic lipid- and polymer-complexed plasmid DNA were shown to have a significant transfection activity in vitro but their use in vivo has been hampered by the decrease in transfection efficiency mediated by non-specific electrostatic interactions with serum components.
