The addition reactions of the C-centred and the N-centred Glycine radicals to the side walls of an armchair (4,4) Single Walled Carbon Nanotube are investigated by density functional theory. It is found that the N-centred Glycine radical binds strongly to the tube, having an interaction energy of 22 kcal/mol. In contrast the C-centred radical which is 22.7 kcal/mol lower in energy than the N-centred radical, has no binding energy upon addition to the tube walls.
