Abstract: Synthesis of boronic acid functionalized superparamagnetic iron oxide nanoparticles has been reported. Magnetite nanoparticles were prepared by simple co-precipitation from Fe2+ and Fe3+ solution. m-Aminophenyl boronic acid was attached to iron oxide particles through 3,4-dihydroxy benzaldehyde through CfN bond. X-ray diffraction and selected area electron diffraction have shown the formation of inverse spinel phase magnetite of both as prepared and functionalized magnetite particles. FTIR shows attachment of boronic acid-imine onto iron oxide surface through enediol group. Transmission electron microscopy shows well dispersion of boronic acid functionalized particles of size 8±2 nm. Vibration sample magnetometry shows both the particles are superparamagnetic at room temperature having saturation magnetization (Ms) 52 emu/g. In this work the affinity of these boronic acid functionalized particles towards sugar binding was studied taking dextrose sugar as a model. The influence of pH ...
