The electronic and structural responses of B 12 N 12 nanocage toward the adsorption of some nonpolar X 2 molecules: X = (Li, Be, B, N, O, F, Cl, Br, I): A DFT approach
“…40 The adsorption of N 2 and F 2 showed negligible changes on the electronic and structural properties of the B 12 N 12 nanocage. 41 Higher values of adsorption energy were obtained for CH 3 F than for CH 3 Cl on the B 12 N 12 nanocage. 42 NH 3 molecule was adsorbed on the B 12 N 12 nanocage with considerable adsorption energy, while the PH 3 and AsH 3 molecules were relatively weakly adsorbed.…”

“…It has reported that the B 12 N 12 fullerene is the most stable nanostructure 25 . The interaction of various compounds such as nonpolar X 2 compounds (XLi, Be, B, N, O, F, Cl, Br, I), 26 hydrogen halides, 27 pyrimidine nucleotide, 28 H 2 S gas, 29 aspirin, 30 and methanol 31 with the B 12 N 12 fullerenes have investigated. Recently, we have studied the interaction of alprazolam, 32 solariamfetol, 33 sulfanilamide, 34 and Zolinza 35 drugs with the fullerenes using density functional theory (DFT) calculations.…”
The adsorption of Resveratrol (RSV) drug on surfaces of the pure B12N12 and Mg‐decoration B12N12 fullerenes at physiological PH was studied using density functional theory and time‐dependent density functional theory methods at the B3PW91/6‐31+G* level at T = 298.15 K and 1 atm in the solvent (water) with a dielectric constant of 78.4. The adsorption energy (Eads) of RSV on two fullerenes have investigated through hydroxyl (‐OH) groups. The adsorption effect of the RSV on the bond lengths, electronic properties, UV spectra, and excited states of B12N12 and Mg‐B12N12 is detected. Natural bond orbital analysis shows a charge transfer between the RSV and two fullerenes. The electron location function (ELF) and localized orbital locator (LOL) values show that interaction between reactive atoms of RSV (O atoms) and B atom of B12N12 are an electrostatic and partially covalent character. The study interaction of RSV with the B12N12 and Mg‐decoration B12N12 can be used in the field of drug delivery and adsorption on metal surfaces.
“…Spherical boron-nitride nanoclusters (BNNCs) were first synthesized in 1994, [25,26] and they have attracted many theoretical and experimental studies alike. [27][28][29][30][31][32][33][34][35] Oku et al [26] reported that BN nanoclusters could efficiently be synthesized using an arc melting method. The existence of B 36 N 36 and the singly doped Y@B 36 N 36 derivatives was reported through high-resolution electron microscopy, mass spectrometry and characterized by molecular mechanics and MO calculations.…”
Quantum chemical investigation using density functional theory (DFT) approach is performed to assess the interactions of the anticancer 5‐fluorouracil (FU) drug and B36N36 nanocluster. The alkali (AMs) and alkaline earth (AEMs) metals encapsulated B36N36 nanoclusters are also considered for FU adsorption. Results indicate the significant interaction of FU drug with pristine as well as encapsulated boron‐nitride nanoclusters. Accordingly, the electronic structure of the nanoclusters is very sensitive to the FU adsorption. The resulting complexes have less energy gap than the bare ones, which can produce an appropriate signal for detection of the FU drug. Adsorption of six FU molecules on the top of each nanocluster indicates their high capacity for FU drug loading. The FU molecules also interact effectively with the AMs and AEMs encapsulated nanoclusters in the aqueous medium, which facilitates the drug delivery. The studied complexes have higher dipole moments in aqueous phase than in vacuum medium. The pristine and encapsulated B36N36 nanoclusters are suggested as prospective novel delivery agents and detectors for FU drug thanks of their suitable features.
