Iron oxide (e.g., Fe3O4 or γ-Fe2O3) nanoparticles are promising candidates for a variety of biomedical applications ranging from magnetic hyperthermia therapy to drug delivery and biodetection due their superparamagnetism, nontoxicity, biodegradability. While particles small size (below critical size, ∼20 nm) display superparamagnetic behavior at room temperature, these tend penetrate highly sensitive areas the body such as blood–brain barrier, leading undesired effects. In addition, possess...
Abstract Iron oxide nanoparticles (IONPs) are widely used for biomedical applications due to their unique magnetic properties and biocompatibility. However, the controlled synthesis of IONPs with tunable particle sizes crystallite/grain achieve desired functionalities across single‐domain multi‐domain size ranges remains an important challenge. Here, a facile synthetic method is produce iron nanospheres (IONSs) controllable crystallinity tunability. First, highly crystalline Fe 3 O 4 IONSs...
Magnetic nanoparticles are extensively utilized as markers/signal labelling in various biomedical applications. Detecting and distinguishing magnetic signals from similarly sized moving microfluidic systems is crucial yet challenging for biosensing. In this study, we have developed an original method to detect differentiate superparamagnetic (SPM) ferrimagnetic (FM) of comparable sizes. Our approach utilizes a highly sensitive magnetic-coil-based sensor that harnesses the combined effects...
Nickel-zinc ferrite (NZF) compounds, renowned for their mixed spinel structures, hold significant promise diverse applications in high-frequency devices and biomedicine. This study utilizes solvothermal synthesis to produce NZF nanoparticles (NPs) with tunable diameters ranging from 40 300 nm. These NPs exhibit polycrystalline crystallite sizes tailored be approximately 8 nm, a pivotal factor preserving superparamagnetic (SPM) properties across broad size spectrum. A combination of scanning...

Iron oxide (e.g., Fe$_3$O$_4$ or Fe$_2$O$_3$) nanoparticles are promising candidates for a variety of biomedical applications ranging from magnetic hyperthermia therapy to drug delivery and bio-detection, due their superparamagnetism, non-toxicity, biodegradability. While particles small size (below critical size, ~20 nm) display superparamagnetic behavior at room temperature, these tend penetrate highly sensitive areas the body such as Blood-Brain Barrier (BBB), leading undesired effects....
Magnesium ferrite (MgFe2O4) and silica-coated MgFe2O4 nanoparticles were grafted with poly(cysteine methacrylate) (i.e., MgFe2O4/PCysMA MgFe2O4@SiO2/PCysMA nanocomposites) to study pH-tunable adsorption enhanced capacities for the of anionic indigo carmine (IC) cationic methylene blue (MB) dyes. Several characterization techniques XRD, FTIR, TGA, ζ potential analysis, VSM, FE-SEM, TEM, N2 adsorption–desorption isotherm, XPS) indicated successful syntheses these nanocomposites. The behaviors...
