Abstract The electronic sensitivity and effectiveness of the pristine, Fe,‐ Mg‐, Al‐ Ga‐doped ZnO nanoclusters interacted with 5‐fluorouracil (5‐FU) anticancer drug are theoretically investigated in gas phase using B3LYP/wB97XD density functional theory calculations LANL2DZ basis set. It is concluded that 5‐FU adsorption on doped has relatively higher energy as compared pristine zinc oxide. A number thermodynamic parameters, such band gap ( E g ), ad molecular electrostatic potential, global...
Abstract Anti‐seizures have been frequently used for a long time. Most of these antiepileptic drugs, which are on daily basis, central nervous system depressants, and their excessive use damages the respiratory system. Therefore, in order to achieve desired therapeutic goals, avoiding side effects drug interactions, it is very important targeted medications. Among metal–organic frameworks (MOFs), ZIF nanoparticles several advantages such as smooth capillary flow slow release circulating...
