Schematic representation of dendriplexes prepared from a plasmid DNA (pDNA) and two generations of PEG-GATG block copolymers as nanostructures with core–shell stoichiometry. Expression of EGFP in HEK-293T cells transfected with dendriplexes prepared with increasing molar ratios of PEG-[G3]-NH₂/[G3]-NH₂: a 0% (solely G3), b 0.5%, c 1%, d 5%, e 10%, f 20%, g 50%, and h 100% (solely PEG-G3).
