Summary: Magnetization is a measurable property of materials that provides information about their electronic structure, phase purity, and impurities. Superparamagnetism, a size-dependent property of magnetic materials, has been underexplored in the field of quantum materials. In this study, a statistical model is used to analyze a dataset of variable-size superparamagnetic Fe3O4 particles. The results show that parameters of the intrinsic probability distribution, such as the maximum susceptibility, are more suitable for describing the superparamagnetic behavior compared to standard measures like saturation magnetization. This analysis has potential applications in synthesis diagnostics and prediction of new properties and functionality.

Summary: In recent years, a wide range of nanomaterials, including magnetic nanoparticles, have been extensively studied for various purposes. Iron oxide nanoparticles and superparamagnetic iron oxide nanoparticles have attracted significant attention due to their physicochemical and magnetic properties, as well as their compatibility with organic or inorganic compounds. The incorporation of these nanoparticles into hydrogels has garnered interest in the field of biomedicine. This review discusses various synthesis methods for magnetite nanoparticles and introduces different processing techniques for magnetite-based nanocomposites in hydrogels. The characterization techniques commonly used to study magnetic nanoparticles and magnetic gels are also discussed.

Summary: The use of graphene and its derivatives in the biomedical field is expanding, from bioimaging to drug delivery and tissue engineering. Graphene family-incorporated scaffolds offer superior properties such as enhanced mechanical properties and large surface area. They also address issues related to cytotoxicity and immune response when used in 3D scaffolds. Positive effects on cell proliferation, osteogenic differentiation, and antibacterial properties have been observed in vitro and in preclinical studies for bone defects treatment, but more in vivo studies are needed to fully assess their potential.

Summary: This study described a novel magnetofection system for delivering therapeutic miRNAs to promote osteogenesis and angiogenesis in patients with lumbar degenerative disc disease (DDD). Co-stimulation with electromagnetic field (EMF) and iron oxide nanoparticles (IONPs) significantly enhanced magnetofection efficiency. In vitro, magnetofection of miR-21 into bone marrow mesenchymal stem cells (BMSCs) and human umbilical endothelial cells (HUVECs) influenced their cellular behaviour and promoted osteogenesis and angiogenesis.

Summary: Collagen fibers in the body have a complex arrangement, which plays an important role in cell adhesion, migration, proliferation, and secretion. Oriented collagen fiber scaffolds have shown exciting results in tissue repair. Bone is crucial for bearing loads in the human body, and the arrangement of collagen fibers in bone significantly affects its mechanical properties and physiological functions. Oriented collagen fiber scaffolds can promote new bone growth and induce cells to secrete oriented extracellular matrix. However, the complex arrangement of collagen fibers in bone poses challenges for bone tissue repair and bionics.

Summary: This review discusses the role, physicochemical properties, potential applications, and toxicological effects of magnetic nanoparticles (MNPs) in complex biological systems. MNPs have been widely used in various industries, leading to increased interactions with biological organisms. However, the full impact of these particles on complex biological systems and the toxicology aspects of their biomedical applications remain unclear, with mixed and inconclusive results. A consolidative framework that considers the physicochemical properties and potential risks of MNPs is necessary for their future manageable applications.

Summary: This study analyzed the spinal orthopedic mechanism, including alignment, growth, and morphology, by examining a spine that underwent four distraction operations. The findings showed that traditional growing rod (TGR) can improve spinal alignment, but re-unbalance and unsynchronized growth can occur after multiple distractions. The growth rate diminishes and asymmetric growth is observed. The study suggests that combining TGR with osteotomy fusion of lumbar segments may be a good choice for severe early-onset scoliosis.
