Iron oxide nanoparticles, recognized for their superparamagnetic properties, are promising for future healthcare therapies. However, their extensive use in medicine and electronics contributes to their discharge into our environments, highlighting the need for further research on their cellular damage effects on aquatic organisms. While the detrimental properties of other compounds have been stated in the early-life stages of fish, the cytotoxic consequences of superparamagnetic iron oxide nanoparticles (SPIONs) in these stages are still unexplored.

Therefore, the enrichment of tumor-antigen specific CAR-T cells in the desired region is critical for improving therapy efficacy and reducing systemic on-target/off-tumor side effects. Here, we functionalized human CAR-T cells with superparamagnetic iron oxide nanoparticles (SPIONs), making them magnetically controllable for site-directed targeting.

In this study, we report the synthesis of iron oxide nanoparticles (FeONPs) using micro-emulsion-hydrothermal method. By adjusting the synthesis temperature, we successfully produced FeO nanorods and nanospheres. In addition, the 2-octanol, and the surfactant cetyltrimethylammonium bromide served as a solvent in the synthesis process.

Objectives: Accurate lymph node (LN) staging is crucial for managing upper abdominal cancers. Ultrasmall superparamagnetic iron oxide (USPIO)-enhanced magnetic resonance imaging effectively distinguishes healthy and metastatic LNs through fat/water and -weighted imaging. However, respiratory motion artifacts complicate detection of abdominal LNs.

Solid magnetic liposomes (ML, nanocomposites comprising lipid bilayers that incorporate magnetic nanoparticles) may be used in wastewater remediation: the lipid bilayer creates an environment where organic pollutants preferentially partition instead of water and the manipulation of ML with an external magnet enables an easy recovery from water. This study aimed to assess the system's potential for water remediation, focusing on ML ability to remove common pollutants in industrial wastewater. Specifically, alkylphenol ethoxylates (APEO) were used as the archetype for organic pollutants.
