In this study, chemical reactivity of (4,0) and (5,0) AlN nanotubes by interaction with nitrosamine molecule as a carcinogen agent was investigated using the B3LYP/6-311++G (d) level of theory. The HOMO–LUMO gap, electronic chemical potential (m), hardness (ƞ), softness (S), the maximum amount of electronic charge (DNmax), and electrophilicity index (ω) for the monomers and complexes were calculated. The results show that the interaction of NA with nanotubes cab be changes electronic properties of nanotubes. To investigate the interactions between the NA molecule and nanotubes, analysis of atoms in molecules was performed at B3LYP/6-311++G (d) level of theory. The Multiwfn program was used to calculation of electron density of states (DOS). The charge transfer in complexes was calculated using the NBO analysis. The results of this work were compared with the results of adsorption of NA molecule on BN nanotubes. It is expected that the AlN nanotubes can be used as sensor for detection of NA molecules.
