چکیده :
This study examines the interaction of enalapril molecule with single-walled Boron nitride nanotube (SWBNNT) for drug delivery purposes using density functional theory (DFT) calculations. Two phases of the gaseous and water were considered for DFT calculations on the investigated model. The adsorption energy of enalapril and nanostructure calculated in both phases. The negative values of adsorption energy, indicate that the enalapril and nanostructure interaction was exothermic. The value of adsorption energy in the gaseous phase (-0.5248 eV) was higher than that in the water phase ( -0.4458 eV) , which indicating a stronger interaction in the gas phase. To evaluate the effect of molecular adsorption on the electronic properties of the nanostructure, the density of states (DOS) was investigated. The results showed that BNNT got closer to the Fermi energy level after the adsorption of drug. The value of ΔEg for BNNT@Enalapril was -0.6011eV; this shows that the conductivity of BNNT increases after the adsorption of enalapril. Therefore, BNNT can be suitable delivery system for enalapril drug and also BNNT can act as the enalapril nanosensor.
