Molecular Dynamics Simulations on Polycaprolactone Nanocomposite Drug Delivery Systems
- 41 Downloads
Molecular dynamics (MD) simulations were accomplished on polycaprolactone (PCL) nanocomposite systems composed of hydroxyapatite (HA) nanoparticles (0 and 2%) to deliver ifosfamide (IF) anticancer drug in order to achieve the most suitable drug delivery system (DDS). Smaller inter-chain distances measured for the PCL-HA2-IF established that greater intermolecular interactions were occurred in the PCL-HA2-IF as a result of hydrogen bonds formation and electrostatic interactions among the PCL polymeric chains, HA NPs as well as IF molecules. It was found that the drug diffusion was slower/more controlled in the PCL-HA2-IF which would cause a more effective drug delivery.
