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. J.; Mohealdeen, S. M.; Hsu, C. Y.; Jumanazarov, U. A.; Maaliw III, R. R.; Mirzaei, M.; Da'i, M.By the importance of developing detection materials and devices, the current work was done to provide molecular insights into the exploration of amphetamine (AMP) adsorbents/sensors through the density functional theory (DFT) assessments of carbon (g-C) and boron nitride (g-BN) graphdiyne nanosheets. Since AMP could be very harmful in an overdose level, then its careful detection is very important for employing the appropriate emergency cares and activities. The optimization calculations were performed to stabilize the structures of singular models and their corresponding AMP@g-C and AMP@g-BN complex, in which a higher strength was found for the formation AMP@g-C complex. 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 Computational assessments of sumanene-hydroxyurea conjugations for proposing a novel drug design and delivery platform(Elsevier, 2023) Saadh, M. J.; Mirzaei, M.; Ahmed, H. H.; Taher, W. M.; Alwan, M.; Meliyev, H.; Maaliw III, R. R.Sumanene-hydroxyurea (SUM-HYD) conjugations were assessed based on the density functional theory (DFT) computational assessments for proposing a novel drug design and delivery platform. The structural geometry optimizations and electronic molecular orbital features evaluations were done to assess the investigated systems. The results indicated the existence of a semi-cup-like structure for the SUM counterpart, in which the in-side and out-side of the surface structure were participated in interactions with the HYD counterpart to yield the SHi and SHo complexes of SUM-HYD conjugation. The existence of interactions were analyzed and the models were assessed based on the involving interactions and the finally obtained configurations revealed a better suitability of the SHo conjugation in comparison with the SHi conjugation. Additionally, the electronic molecular orbital features indicated a lower hardness for the SHi conjugation even in comparison with the singular HYD substance. Furthermore, the models were recognizable by the SUM sensing functions towards the HYD drug substance. Assessing the impacts of water and ethanol media on the Gibbs free energy of SUM-HYD conjugations indicated the stability of models in both media with a priority of water medium. As a result, the models were stabilized and their features indicated benefits of formations of such SUM-HYD conjugated systems for approaching a novel drug design and delivery platform.Öğe Explorations of structural and electronic features of an enhanced iron-doped boron nitride nanocage for adsorbing/sensing functions of the hydroxyurea anticancer drug delivery under density functional theory calculations(Elsevier, 2023) 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 Metal-doped fullerenes as promising drug carriers of hydroxycarbamide anticancer: Insights from density functional theory(Elsevier, 2023) Salem-Bekhit, M. M.; Al Zahrani, S.; Alhabib, N. A.; Maaliw III, R. 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. In this regard, the enhanced models of FeF, NiF, and ZnF doped fullerenes were found suitable to work as promising carriers of Hyd anticancer regarding the drug delivery issues by the formation of interacting Hyd@FeF, Hyd@NiF, and Hyd@ZnF complexes in meaningful levels of structural and electronic features.
