Summary: The multidisciplinary research field of regenerative medicine and tissue engineering has effectively resolved numerous issues related to bone tissue disorders caused by aging, diseases, and injuries. Nanotechnology, combined with tissue engineering, has made significant contributions to tissue repair and regeneration. Studies have demonstrated that the incorporation of magnetic nanoparticles (MNPs) into composite scaffolds enhances their healing capabilities for bone defects. Furthermore, the induction of osteogenic differentiation in mesenchymal stem cells (MSCs) has been investigated and verified in the presence of these nanoparticles. This article reviews the different types and unique properties of MNPs, as well as their application in healing damaged bone tissue. It also discusses the molecular effects of MNPs on cell behavior, particularly in osteogenesis. Lastly, the potential applications of MNP-containing nanocomposite scaffolds in the treatment of bone lesions and injuries are outlined. Overall, this review article emphasizes the role of nanocomposite scaffolds containing MNPs as a solution for treating bone defects in tissue engineering and regenerative medicine.

Summary: The addition of P in FeSiB(P)NbCu nanocomposite alloy leads to grain refinement of alpha-Fe nanocrystals, resulting in reduced coercivity and enhanced soft-magnetic properties. This synergistic grain refinement mechanism is explained by the activation energy of crystallization, selective solute re-distribution, and enhanced stabilization of intergranular amorphous matrix. The optimal soft-magnetic properties are achieved in the 4 at% P alloy.

Summary: An innovative approach to fabricate lightweight, highly sensitive 3D conductive nanofiber sponges for pressure sensors was reported. The 3D sponges were prepared by self-assembly of electrospun carbon nanofibers/aminated Fe3O4 and reduced graphene oxide (rGO) nanosheets. The orientation and distribution of the graphene nanosheets were further regulated by an external magnetic field to improve the sponge's performance.

Summary: Diseased or injured nervous systems have limited self-repair and regenerative capability, leading to lifelong disability and even death. Biomaterial scaffolds with specific properties, such as electroconductivity, can guide the selective differentiation of neural stem/progenitor cells (NSPCs) into neurons and oligodendrocytes. Electroconductive and mechano-competent scaffolds made of shape-memory polyurethane-polycaprolactone (PUCL) nanofibers and carbon nanotubes (CNTs) were prepared and showed promising potential for neural tissue regeneration.

Summary: The improved peri-implant bone response seen with the platform-switching concept may be due to the reduced release of metal ions from the implant-abutment surfaces. This study investigated the effect of different implant-abutment couplings on osteoblasts' function and found that platform-matched couplings resulted in higher rates of cell apoptosis and upregulation of genes related to bone resorption. These adverse biological responses may be associated with the increased release of metal ions from platform-matched couplings, indicating the potential role of corrosion products in crestal bone loss around dental implants.
