The effect of electric fie ld on interaction of glycine w ith (۶, ۰) single-walled boron nitride nanotube

Since the discove ry of carbon nanotubes, extensive studies have been perfor med on anal ogous tubular nanomaterials, such as boron n itride nanotubes (BNNTs) . BNN Ts possess many uniqu e properties, therefore BNNTs have been prop osed as mo re proper m aterials than the CNTs for application in the nano-devices [۱]. Glycin e is the simplest of Į-amino acids, as an important model compound in chemical physics, biophysics and bioch emistry [۲]. The adsorp tion mechanism of amino acids an d biological molecules on the nanot ubes has attr acted a lot of attentio n during the past year s, since it is of great importance both fro m the funda mental and the applied point of view. On the o ther hand, modification of the structural and electrical pro perties by the applying external elec tric field (EF) is an important subject for design ing nano-device. In t his study, we investigated the effect of external EF on the intera ction of glyc ine molecule with (۶, ۰ ) SWBNNT .
