Synthesis and characterization of Fe3O4-NH2 and Fe3O4-NH2-chitosan nanoparticles [PDF]

open access: yesCerâmica, 2021
Abstract Fe3O4 nanoparticles were synthesized and functionalized with (3-aminopropyl) trimethoxysilane (APTMS) and chitosan, forming Fe3O4-NH2 and Fe3O4-NH2-chitosan nanoparticles. The Fe3O4 nanoparticles were synthesized by a co-precipitation method and functionalization was performed in further stages.
