Facile electrosynthesis and characterization of superparamagnetic nanoparticles coated with cysteine, glycine and glutamine

摘要: A novel and facile strategy has been developed for the preparation of cysteine-, glycine- glutamine-coated magnetite nanoparticles (MNPs). According to this strategy, Fe3O4 were electrodeposited from an aqueous electrolyte containing a dissolved iron salt amino acids. simple deposition mode i.e., constant current two-electrode set-up was used in electrosynthesis procedure. The phase deposited confirmed through XRD FT-IR analyses. Morphological observations FE-SEM TEM formation spherical MNP particles with average size 10 nm. cysteine, glycine glutamine layers on surface electro-synthesized proved based FT-IR, DLS TG data. Vibrating sample magnetometery (VSM) measurements prepared oxide have super-paramagnetic nature, since they exhibit high saturation magnetization (Ms ≈ 58 emu g−1), as well as, negligible remnant (Mr) coercivity (Ce). Based obtained results, proposed platform can be considered fast, efficient method surface-coated nanoparticles.
