Summary: This article proposes a novel approach to investigate the field-induced structuration in ferrofluids at room temperature. The experimental setup is used to study the influence of dipolar interaction and particle size of dispersed magnetic nanoparticles in ferrofluids on the static magneto-optical properties under an external magnetic field. The study shows that the shape and size of diffraction fringes in ferrofluids can be influenced by the size and volume fraction of dispersed MNPs, providing insights for the development of potential applications such as tunable optical filters and optical limiters.

Summary: Magnetic iron oxide nanoparticles have broad potential applications in medical and biological sciences. They can be used in targeted drug delivery, internal radiotherapy, magnetic resonance imaging, hyperthermia, and radiolabelling. The appropriate design of nanoparticles allows them to be delivered to desired tissues and organs, with an external magnetic field increasing their biodistribution. Factors such as size, shape, surface charge, coating molecules, and route of administration affect their biodistribution. Modern techniques can determine nanoparticle accumulation sites and concentration in isolated tissues or the body in vivo.

Summary: In this study, the efficiency of alternating current magnetic field and near-infrared heating is enhanced by co-doping Zn and Co in magnetite nanoparticles. Optimum magnetic anisotropy is achieved by tuning the doping concentration to maximize the loss power under each magnetic field. The specific loss power of the nanoparticles greatly exceeds previous levels, making it a promising nanoplatform for multi-modal local hyperthermia therapy.

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: The purpose of this study is to develop a T (2) MRI negative contrast agent with a controllable size and explore the feasibility of dual contrast enhancement by combining T (2) with CEST contrast agents. The study was conducted in vitro with HCT-116 human colon cancer cells. Fe3O4 nanoparticles (NPs) with a controllable size and no toxicity were successfully synthesized, and by combining them with a CEST contrast agent, the two contrast agents could be imaged simultaneously.

Summary: This study demonstrates the effect of in situ magnetic separation on the size and shape of iron oxide nanoparticles produced through coprecipitation. The magnetic array efficiently removes the nanoparticles from the reaction front, preventing their further growth and agglomeration. This method is applicable for large-scale production of iron oxide nanoparticles with tuned size and morphology.

Summary: Noncontact manipulation of cells in regenerative medicine using superparamagnetic iron oxide nanoparticles (SPIONs) allows for new possibilities in tissue engineering. SPIONs can be used as drug transporters, contrast agents, or to make cells maneuverable by magnetic forces. Different SPION coatings, such as PAM and citrate, show good cellular loading and magnetic controllability of cells. This research demonstrates the potential for using SPIONs in 3D cell cultures and highlights their ability to accelerate spheroid formation and micropatterning.
