Rod-like particles of silica-coated maghemite: synthesis via akaganeite, characterization and biological properties
Original language description
A multistep procedure, employing akaganeite FeO(OH,Cl) as a precursor, was developed for the preparation of rod-like maghemite particles for medical applications. At first, akaganeite rods with length of several hundred nm and width of ≈85 nm were prepared under hydrothermal conditions and were subsequently coated with mesoporous silica. Such coating enabled to maintain the shape of rods during the following steps that involved structural transformation of akaganeite to maghemite, i. e. γ-Fe2O3. Then the original protective coating was removed by alkaline leaching, bare maghemite rods were isolated, and their structure and ferrimagnetic order were characterized by X-ray diffraction, TEM, Mössbauer spectroscopy and SQUID magnetometry. The oxidation state of Fe was unambiguously determined by Mössbauer spectroscopy. At least partial ordering of vacancies in the maghemite structure was evidenced. The silica-coated product did not show any cytotoxicity up to 0.42 mmol(Fe)/L.
