Abstract

This paper reports a novel synthetic process to obtain poly(ethylene glycol)โ€coated magnetite nanoparticles. Magnetite nanoparticles were synthesized by a chemical coโ€precipitation of Fe^2+^ and Fe^3+^ ions under alkaline conditions, which were then coated with poly(ethylene glycol) diacrylate via UVโ€curing in water. The nanoparticles were characterized by means of DLS, FTโ€IR spectroscopy, TGA, TEM, and XPS. The magnetic properties of the magnetic nanoparticles at room temperature were also characterized by the measurement of hysteresis curves using a vibratingโ€sample magnetometer. magnified image

## Abstract Magnetite nanoparticles are synthesized and functionalized with vinyl groups (by silanization reaction with VTMS) and further coated with poly(ethylene glycol) dithiol under UV activation via thiolโ€ene addition. TEM analysis is in a good agreement with DLS analyses and shows that by vin
