Polyethylenimine‐Grafted Multiwalled Carbon Nanotubes for Secure Noncovalent Immobilization and Efficient Delivery of DNA

Key Points

• The aim is to explore the efficiency of DNA immobilization and delivery using polyethylenimine-grafted multiwalled carbon nanotubes.
• DNA is immobilized onto multiwalled carbon nanotubes via electrostatic interactions with grafted polyethylenimine.
• Transfection efficiency is compared to that of pure polyethylenimine.
• The polyethylenimine-grafted multiwalled carbon nanotubes achieve DNA delivery efficiency similar to or higher than pure PEI.
