Novel magnetic core-shell Fe3O4 polypyrrole nanoparticles functionalized by peptides or albumin
Résumé
Novel magnetic core-shell iron oxide nanoparticles, covered by polypyrrole which is functionalized by covalent attachment of glycyl-leucine or bovine serum albumin were synthesized using N-hydroxysuccinimide as activating reagent. The morphology of the functionalized magnetic nanoparticles was investigated by DLS and HRTEM, showing a core-shell structure. The structures of magnetic nanoparticles based on functionalized polypyrrole were investigated by FTIR spectroscopy and X-ray diffraction and the magnetic properties were determined by magnetization measurements.
