Abstract:
In this study, we investigated the interaction of the anticancer drug Hydroxyurea (HU) with graphdiyne (GDY) nanosheet by using DFT-D3 calculations. Results show that this two-dimensional surface is a semiconductor with a direct band gap of 0.47 eV. The adsorption energy of the HU drug onto GDY for different positions, namely on 18-membered ring (H1), on hexagonal ring (H2) and on acetylenic linkage (B) was found to be −0.507, −0.326 and −0.150 eV, respectively. Values of the adsorption energies show that the drug adsorption on the H1-position is more favourable, energetically. This weak physical adsorption can deliver the drug to the target cells to treat head and neck cancer and chronic leukemia and releases it easily.
