Abstract :
Further progress in examining the suitability of carbon nanotubes for single-biomolecule sensing has been made via ab initio simulations using the density functional theory/non- equilibrium green´s function approach. Adsorption of different amino acids on short carbon nanotubes is predicted to cause different changes in local densities of states, transmission coefficient, and current.
