Magnetic Force Microscopy Characterization of Superparamagnetic Iron Oxide Nanoparticles (SPIONs)

Synthesis and characterization of superparamagnetic Iron Oxide nanoparticles (SPIONs) stabilized by Glucose, Fructose and Sucrose

The aim of this study is to obtain polysaccharide (Glucose, Fructose and Sucrose) stabilized superparamagnetic iron oxide nanoparticles (SPIONs) by Co-Precipitation method. As prepared iron oxide nanoparticles have been characterized by X-ray Diffraction (XRD), Fourier Transform infrared (FTIR) spectroscopy, UV–Vis NIR spectroscopy, High Resolution Transmission Electron Microscope (HRTEM) and V...

Magnetic Force Microscopy (MFM) Characterization of Superparamagnetic Nanoparticles

“Magnetic Force Microscopy and Energy Loss Imaging of Superparamagnetic Iron Oxide Nanoparticles”

We present quantitative, high spatially resolved magnetic force microscopy imaging of samples based on 11 nm diameter superparamagnetic iron oxide nanoparticles in air at room temperature. By a proper combination of the cantilever resonance frequency shift, oscillation amplitude and phase lag we obtain the tip-sample interaction maps in terms of force gradient and energy dissipation. These phys...

UPTAKE AND INTRACELLULAR TRAFFICKING OF SUPERPARAMAGNETIC IRON OXIDE NANOPARTICLES (SPIONs) IN PLANTS

The uptake and movement of iron nanoparticles in elodea plants have been detected by the ESR method. This method is applied for the first time for the monitoring of the translocation, movement and uptake iron nanoparticles in plant organs. Exposition of stem, root or leaves of elodea in superparamagnetic iron nanoparticles (SPIONs) with concentration 12.9 mg/mL and less 10 times showed that iro...
