Density functional theory calculations were performed to study the interactions between the host material Si-doped fullerene and the drug molecules
paracetamol, a pain and fever reducer, and hydroxyurea, a drug for leukemic treatment. All atoms were relaxed so that the atomic force was less than 5.0 × 10−3 eV/Å. Structural and electronic properties, such as adsorption energy, formation energy, and charge transfer, were calculated. Results showed that Si-doped fullerene had more negative adsorption energy and lower formation energy than undoped fullerene, indicating that
drug molecules could be chemisorbed in Si-doped fullerene. These results contribute to the future drug delivery application.
