Electro-grafting
Electro-grafting (eG™) is an electrochemical coating technology creating ultra-thin (100-500 nm) brushes of vinylic polymers covalently bonded onto metallic or semiconductor surfaces [1,2]. The surface to be coated is dipped into a bath of vinylic monomers in an organic solvent, and a voltage is applied which triggers the initiation of the polymerization reaction: "hairs" of polymers are grown in situ on the surface, up to a few hundreds of nanometers [3].
Endothelial cells migrate on eG™ layer about x2 times faster than on a bare metal surface, thus accelerating the healing of the wounded surface of arteries after PCI [4].
