description

International audience; In recent years great interest has emerged in the development of nanocarriers for drug transport. One of themajor challenges is to obtain a drug delivery system able to control the drug release profile, transportabsorption and distribution, in the view of improving efficacy and safety. Herein, we present theoreticalresults based on density functional theory (DFT) to determine the best adsorption site for the anticancerifosfamide molecule in boron nitride nanotubes. For this functionalized system we determine thedependence of the adsorption energy on the displacement of molecules in the outer and inner boronnitride surfaces, together with their local morphological and charge modifications. Quantum simulationsshow that the most stable physisorption state is located inside the nanotube, with no net charge transferbetween each subsystem, and no barrier energy at the nanotube entrance. This demonstrates thatchemotherapeutic encapsulation is the most favorable way for ifosfamide to be vectorized.
