Iron oxide magnetic nanoparticles have been employed as potential vehicles for a large number of biomedical applications, such as drug delivery. This article describes the synthesis, characterization and in vitro cytotoxic in COVID-19 cells evaluation of DMSA superparamagnetic iron oxide magnetic nanoparticles. Magnetite (FeO) nanoparticles were synthesized by co-precipitation of iron salts and coated with meso-2,3-dimercaptosuccinic acid (DMSA) molecule. Structural and morphological characterizations were performed by X-ray diffraction (XRD), Fourier transformed infrared (FT-IR), magnetic measurements (SQUID), transmission electron microscopy (TEM), and dynamic light scattering (DLS). Our results demonstrate that the nanoparticles have a mean diameter of 12 nm in the solid-state and are superparamagnetic at room temperature. There is no toxicity of SPIONS-DMSA under the cells of patients with COVID-19. Taken together the results show that DMSA- FeO are good candidates as nanocarriers in the alternative treatment of studied cells.

Organic anode materials have garnered attention for use in rechargeable Li-ion batteries (LIBs) owing to their lightweight, cost-effectiveness, and tunable properties. However, challenges such as high electrolyte solubility and limited conductivity, restrict their use in full-cell LIBs. Here, we report the use of highly crystalline Cl-substituted contorted hexabenzocoronene (Cl-cHBC) as an efficient organic anode for full-cell LIBs.

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.

This study investigates the biosynthesis of iron oxide nanoparticles (FeONPs) using the cell-free supernatant of Pseudomonas fluorescens. The synthesized FeONPs were characterized through UV-VIS, XRD, FTIR, FESEM, EDX, TEM, BET, and VSM analyses. The XRD results confirmed that FeONPs were successfully synthesized and EDX analysis indicated that iron accounted for 89.

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.

Background The sentinel lymph node biopsy (SLNB) is the standard method used to determine the stage of breast cancer in patients with no clinical signs of axillary involvement. The current gold standard for the intraoperative assessment of the axilla involves the use of dual radioisotope and patent blue dye. However, researchers have been studying the use of superparamagnetic iron oxide Magtrace® (Endomagnetics Limited, Cambridge, United Kingdom) agents as an alternative to overcome the limitations of the standard SLNB technique.
