Controllable synthesis, magnetic and biocompatible properties of Fe3O4 and alpha-Fe2O3 nanocrystals
Link to Journal Abstract
Iron oxide nanocrystals (NCs) with a series of well-controlled morphologies (octahedron, rod, wire, cube and plate) and compositions (Fe3O4 and alpha-Fe2O3) were synthesized via a facile hydrothermal process. The morphological and compositional control of various iron oxide NCs was based on the regulations of precursor thermolysis kinetics and surfactants. The obtained samples were characterized by XRD, SEM, TEM, SQUID and cytotoxicity test. These as-prepared iron oxide NCs showed excellent magnetic properties and good biocompatibility, paving the way for their high-efficiency bio-separation and bio-detection applications.
This paper describes the preparation and characterization of iron oxide nanocrystals (NCs) with a series of well-controlled morphologies (octahedron, rod, wire, cube and plate) and compositions (Fe3O4 and alpha-Fe2O3), and includes cytotoxicity testing of these materials.
