Shortened and oxidized multi-walled carbon nanotubes (MWCNTs) were functionalized with adenine using the amidation strategy. The adenine functionalized MWCNTs (Ad-MWCNTs) were complexed with a uracil substituted ferrocene and characterized by transmission electron microscopy (TEM), high resolution TEM (HRTEM), electron diffraction X-ray spectroscopy (EDX), and atomic force microscopy (AFM). The electrochemical properties of these novel nanohybrids were studied by cyclic voltammetry. The favorable supra-molecular interaction of the electroactive species with the functionalized nanotubes through the efficient adenine-uracil base-pairing can be exploited for the design of new electronic devices.
