“…In all spectra, Fe‐O stretching vibrations appeared in the 559 and 632 cm −1 (Figure 1a). 54 The symmetric and asymmetric stretching vibration of the Si‐O‐Si bonds causes absorption peaks at 455, 802, and 1,083 cm ‐1 53 . Also, the broad spectral range observed at 3,442 cm −1 is associated with the bonding vibrations of hydroxyl groups and adsorbed water molecules 55 .…”

“…The low‐angle XRD pattern of M‐MCM‐41 and M‐MCM‐41@TU‐ZrO samples is presented in Figure 5a,b. The XRD pattern of M‐MCM‐41 shows a strong reflection peak at 2 θ = 2.41° and also a weak peak at 2 θ = 3.93°, indicating a hexagonal ordered mesoporous structure 54 . These reflections became weaker after the immobilization of the zirconium complex on the channels 57 …”

The synthesis and characterization of MCM‐41 magnetic mesoporous material, which has been modified with zirconium‐thiouracil complex (M‐MCM‐41@TU‐ZrO), has been conducted and thoroughly analyzed using an array of techniques such as X‐ray diffraction (XRD), energy‐dispersive X‐ray spectroscopy (EDX), elemental mapping, scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT‐IR), Brunauer‐Emmett‐Teller (BET), inductively coupled plasma‐optical emission spectrometry (ICP‐OES), thermogravimetric analysis (TGA) and vibrating sample magnetometer (VSM). The catalytic performance of M‐MCM‐41@TU‐ZrO was tested in the synthesis of phenyl aryl sulfides through a three‐component coupling reaction of aryl halides/phenolic esters with phenylboronic acid and sulfur powder in the presence of a base in PEG200 at 80–90°C. Also, the synthesis of symmetrical diaryl sulfides using aryl halides and sulfur powder and M‐MCM‐41@TU‐ZrO as a nanocatalyst in dimethyl sulfoxide at 120°C was investigated. A major novelty is that this is the first time that a highly efficient magnetically recyclable zirconium nanocatalyst is used for the synthesis of unsymmetrical diaryl sulfides in the presence of arylboronic acid/S8 system as thiolating agent and phenolic esters as cross‐coupling partners. The other advantages of this method are as follows: (a) the structurally diverse phenyl aryl sulfides have been synthesized in good to high yields in PEG as a green solvent; (b) starting materials, sulfur source, and catalyst are commercially available, cheap, non‐toxic, and chemically stable; and (c) M‐MCM‐41@TU‐ZrO nanocatalyst was easily removed from the reaction mixture using an external magnet and reused numerous times without any significant change in activity.

“…The nonmagnetic HAp/PTH (1–34) moieties were loaded onto the surface of the magnetic support, providing a reasonable explanation for the lower Ms value of the final nanocomposite. However, it is important to note that the actual Ms value of the nanocomposite remained sufficiently high to enable magnetic separation using a standard magnet . Consequently, the distance between Fe 3 O 4 nanoparticles is increased, and the interaction strength is decreased …”

This article presents a comprehensive study of the development of a novel nanocomposite comprising core−shell Fe 3 O 4 @MCM-41 with superparamagnetic properties and hydroxyapatite (HAp). The nanocomposite serves as a pH-responsive nanocarrier, offering an efficient injectable dosage for teriparatide (PTH (1−34)) delivery. The aim is to address the limitations associated with druginduced side effects, precautionary measures, and frequent injections. The nanocomposites, as prepared, were characterized using techniques including X-ray diffraction, Fourier transform infrared, zeta potential, dynamic light scattering, VSM, scanning electron microscopy, and transmission electron microscopy. The nanocomposites' average crystallite diameter was determined to be 27 ± 5 nm. The hydrodynamic size of the PTH (1−34)-loaded nanocarrier ranged from 357 to 495 nm, with a surface charge of −33 mV. The entrapment and loading efficiencies were determined to be 73% and 31%, respectively. All of these findings collectively affirm successful fabrication. Additionally, in vivo medication delivery was investigated using the HPLC method, mirroring the in vitro tests. Utilizing the dialysis approach, we demonstrated sustained-release behavior. PTH (1−34) diffusion increased as the pH decreased from 7.4 to 5.6. After 24 h, drug release was higher at acidic pH (88%) compared to normal pH (43%). The biocompatibility of the PTH (1−34)-loaded nanocarrier was assessed using the MTT assay employing the NIH3T3 and HEK-293 cell lines. The results demonstrated that the nanocarrier not only exhibited nontoxicity but also promoted cell proliferation and differentiation. In the in vivo test, the drug concentration reached 505 μg within 30 min of exposure to the magnetic field. Based on these findings, the Fe 3 O 4 @MCM-41/HAp/PTH (1−34) nanocomposite, in combination with a magnetic field, offers an efficient and biocompatible approach to enhance the therapeutic effect of osteogenesis and overcome drug limitations.

Chiral nanomaterials with unique chiral configurations and biocompatible ligands have been booming over the past decade for their interesting chiroptical effect, unique catalytical activity, and related bioapplications. The catalytic activity and selectivity of chiral nanomaterials have emerged as important topics, that can be potentially controlled and optimized by the rational biochemical design of nanomaterials. In this review, chiral nanomaterials synthesis, composition, and catalytic performances of different biohybrid chiral nanomaterials are discussed. The construction of chiral nanomaterials with multiscale chiral geometries along with the underlying principles for enhancing chiroptical responses are highlighted. Various biochemical approaches to regulate the selectivity and catalytic activity of chiral nanomaterials for biocatalysis are also summarized. Furthermore, attention is paid to specific chiral ligands, materials compositions, structure characteristics, and so on for introducing selective catalytic activities of representative chiral nanomaterials, with emphasis on substrates including small molecules, biological macromolecule, and in‐site catalysis in living systems. Promising progress has also been emphasized in chiral nanomaterials featuring structural versatility and improved chiral responses that gave rise to unprecedented chances to utilize light for biocatalytic applications. In summary, the challenges, future trends, and prospects associated with chiral nanomaterials for catalysis are comprehensively proposed.
