Polyethylenimine coated plasmid DNA-surfactant complexes as potential gene delivery systems

- Nanoparticles result from association between plasmid DNA and surfactants.
- Polyethylenimine coating leads to a drastic increase in cell viability.
- The swelling behaviour of these vehicles can control the release of plasmid DNA.
- These carriers are a new nanoplatform for advances in the gene therapy field.
