DNA hits the wall: DNA is immobilized securely onto the surface of multiwalled carbon nanotubes through electrostatic interactions with grafted polyethylenimine (PEI; see picture). The polyethylenimine-graft multiwalled carbon nanotubes carrying DNA show transfection efficiency for DNA delivery similar to or even several times higher than PEI.
