The optimization of the embedding process focused on three parameters: the molar ratio of zinc(II) ion to 2-methylimidazole (Zn²⁺: HmeIM), the concentration of partially purified lipase, and the duration of embedding process. Various physicochemical characterization techniques were employed to confirm and analyze the embedded lipase, including powder X-ray diffraction (PXRD), transmission electron microscopy (TEM), and energy dispersive X-ray (EDX) analysis. Additional characterization methods such as thermogravimetric analysis (TGA), N₂ adsorption-desorption measurements, and Fourier transform infrared spectroscopy (FTIR) were also conducted for comprehensive analysis. The amount of lipase successfully embedded was quantified using the standard Bradford assay, with CRL₃@nZIF-8(1:35) (<i>Candida rugosa</i> lipase (3.0 mg) immobilized on nano ZIF-8 synthesized with a Zn²⁺:HmeIM ratio of 1:35) achieving the highest immobilization of 89% with loading capacity of 17.7 mg/g.

The synthesized composite was characterized using various techniques, confirming successful immobilization and demonstrating a significant adsorption capacity of 760.1 mg/g, approximately 7.3 times that of the raw biomass (103.1 mg/g). The adsorption process was highly pH-dependent, with optimal removal observed at pH 8.0. Equilibrium data conformed to the Langmuir isotherm model (R² = 0.977), and kinetic analysis followed pseudo-second-order kinetics (R² = 0.997), suggesting chemisorption involving Zn–O and Zn–N coordination, as corroborated by XPS analysis. The analytical method exhibited excellent performance, with LOD of 0.079 µg/L, LOQ of 0.264 µg/L, and RSD of 2.38%. The nanobiosorbent retained over 95% removal efficiency after 10 adsorption–desorption cycles and demonstrated high tolerance to various interfering ions at up to 250 mg/L. Application to microwave-assisted digested bulgur samples yielded recovery rates of 95%-105%, confirming analytical accuracy and minimal matrix effects.

While traditional superatoms rely on structurally enclosed confinement within metallic clusters, this review highlights a distinct regime: coordination‑mediated (non‑enclosed) confinement in metal complexes, where a fully saturated and symmetric ligand sphere generates an effective potential that induces quantized electronic shells without physical enclosure. Three paradigm‑shifting advances are outlined: (1) superatomic character is defined not by geometry but by radial quantization overriding chemical directionality; (2) ligand saturation serves as a chemical tool for potential averaging, enabling shell formation through chemical rather than structural confinement; and (3) <i>f</i>-element complexes such as [Ac(H₂O)₉]³⁺ provide a critical test case, where the superatom model offers the most parsimonious explanation where classical ligand-field approaches fall short.

The results reveal that the doped fullerenes enhance their interaction with the drugs compared to pristine C30 fullerene. Calculated adsorption energies show that B- and N- doping improve the drug’s affinity for the C30 fullerene. B- and N- doped fullerenes change the electronic properties of the combined system, particularly increasing the density of states near the Fermi level, enhancing the adsorption of the drugs. In general, interactions by B-doping are stronger than N-doping, while, clonidine is stronger adsorbed than clopidogrel. In contrast, the C36 doped fullerenes show significant changes in charge density that contribute to repulsion and structural deformation. The interaction of C36-N2 with the drugs is energetically unfavorable while C36-B2 behavior is similar to an un-doped C30 fullerene. An improvement in the adsorption is not observed for dual-atom doping compared to single-atom doping. Similarly, increasing the fullerene size does not show an enhancement in the adsorption behavior.
