Progress in the development of lipopolyplexes as efficient non-viral gene delivery systems

The schematic structure of lipopolyplexes (LPPs), one of the most efficient nonviral vectors, (a) lipopolyplexes with modified polymers, (b) peptide-based lipopolyplexes, (c) lipopolyplexes with modified lipids, and (d) reverse lipopolyplexes.368
