We have characterized the adsorption properties of protein molecules on carbon nanotube surfaces by infrared vibration spectroscopy. We observed the vibration modes of protein molecules from the avidin-adsorbed CNTs. Density of the adsorbed avidin molecules was higher on acid-treated CNTs than on non-treated ones. These results indicate that CNTs are suitable materials for an adsorbent of bio-molecules, and are promising for high-sensitivity bio-sensors and removers of toxic proteins.
