Y.; Saadh, M. J.; Mutee, A. F.; Mumtaz, H.; Tillaeva, G. U.; Mirzaei, M.; Da'i, M.By the importance of developing novel drug delivery platforms, the current research work was done to assess the metronidazole (MET) adsorption by an iron -enhanced nanocone (FeCON) along with density functional theory (DFT) calculations regarding the MET@FeCON conjugated complex systems formations. Comparing the results by a pure nanocone (CON) model showed benefits of the iron -enhancement for approaching suitable MET@FeCON conjugated complex systems. A managing role of iron atom was also observed for the formation of complexes, in which the results were in a comparable mode for the formation of strong interactions inside the complexes. Variations of frontier molecular orbitals and their related features leaded to the evaluation of characteristic features and monitoring significant variations from the singular state to the complex state or even among the complexes. In this case, the models were also distinguishable for being monitored among the conjugations formations. As a result, the models were found suitable regarding the developments of drug delivery platforms in both terms of conjugations formations and electronic features detections.Öğe Assessments of carbon and boron nitride graphdiyne nanosheets for exploring the amphetamine drug adsorbents/sensors along with density functional theory(Elsevier, 2023) Saadh, M.

Bothe complexes were stable enough to be recognized based on their formations and also by monitoring the variations of frontier molecular orbital features. The results indicated that the formation of AMP@g-BN complex could be used for an immediately detection whereas the formations of AMP@g-C complex could be used for a timely detection. Both complexes were found reusable based on the formation of non-covalent interactions between the substances, in which the stabilities and molecular orbitals features proposed both of g-C and g-BN nanosheets as suitable adsorbent/sensor materials of AMP substance for developing novel detection materials and devices.Öğe Density functional theory assessments of an iron-doped graphene platform towards the hydrea anticancer drug delivery(Elsevier Science Sa, 2024) Saadh, M.

J.; Mirzaei, M.; Abdullaeva, B. S.; Maaliw III, R. R.; Da'i, M.; Salem-Bekhit, M. M.; Akhavan-Sigari, R.An iron-doped boron nitride (FBN) nanocage was investigated for adsorbing/sensing the hydroxyurea (Hyd) anticancer for the smart and targeted drug delivery processes. Optimizations were done under density functional theory (DFT) calculations and the properties were obtained. Interaction of Hyd with each of FBN and BN nanocages yielded four configurations of Hyd@FBN and Hyd@BN complexes. The FBN nanocage surface was found better for interacting with the Hyd counterpart; stronger Hyd@FBN complexes than the Hyd@BN complexes were obtained. The electronic frontier molecular orbital features showed a stronger tendency of complex formations for the FBN nanocage by a shorter energy gap for a better interaction with the Hyd substance. The adsorbing features indicated a meaningful recovery time and those of sensing features indicated a meaningful conductance rate for the investigated FBN nanocage. As a consequence, the FBN nanocage was proposed for involving in the drug delivery processes but still requiring further investigations.Öğe Exploring the naproxen adsorption at the surface of iron-decorated C24 fullerene-like nanocages for providing drug delivery insights along with DFT calculations(Elsevier Science Sa, 2024) Hsu, C.

NPX is among the important non-steroidal anti-inflammatory drugs (NSAIDs), in which its enhancement has been still under development. Accordingly, the focus of this work was on the customization of a carrier model for the NPX drug by investigating the electronic and structural features of interacting conjugated systems. To do this, three iron-decorated nanocages including FeC24, FeC23, and FeC22 models were prepared to assess the adsorption process to yield the NPX@FeC24, NPX@FeC23, and NPX@FeC22 conjugated systems. Different levels of electronic molecular orbital levels and adsorption strengths were achieved regarding the interaction of NPX and iron-decorated nanocages, in which the NPX@FeC22 model was at the highest level of strength and also electronic variations. Accordingly, suitable adsorption and detection of NPX drug were found by the assistance of iron-decorated nanocage models. Especially in the water solvent, the models of conjugations were found still stable by the advantage of iron-decorated conjugated systems. The results of this work could be proposed for further study of NPX drug delivery issues based on the iron-decorated fullerene-like nanocages.Öğe Metal-doped fullerenes as promising drug carriers of hydroxycarbamide anticancer: Insights from density functional theory(Elsevier, 2023) Salem-Bekhit, M.

R.; Da'i, M.; Mirzaei, M.Assessing an idea of metal-doped fullerenes (MF) as promising drug carriers of hydroxycarbamide; also known as hydroxyurea, (Hyd) anticancer was done in this work by performing density functional theory (DFT) calculations. A model of carbon fullerene was doped by each of iron (Fe), nickel (Ni), and zinc (Zn) transition metal atoms to provide enhanced FeF, NiF, and ZnF doped fullerenes for working towards the Hyd anticancer regarding the drug delivery issues. The model were optimized and their evaluated features indicated a possibility of occurrence of MF -> Hyd@MF mechanism through the involving O...M and H...C interactions from the Hyd side to the MF side. The longest recovery time duration was supposed to be found for the Hyd@ZnF complex because of the largest strength and the highest conductance rate variation was supposed to be found for the Hyd@NiF complex because of the smallest energy gap. However, all the complex models were in a reasonable level of formations and electronic variations to be monitored for approaching a sensing or detecting function.
