Fabrication of core–shell CoFe₂O₄@HAp nanoparticles: a novel magnetic platform for biomedical applications

Abstract

Biocompatible core–shell CoFe2O4@HAp magnetic nanoparticles were successfully prepared by a simple two-step hydrothermal process, and their physicochemical and magnetic properties were studied.

Antibacterial and antibiofilm activities of silver-decorated zinc ferrite nanoparticles synthesized by a gamma irradiation-coupled sol–gel method against some pathogenic bacteria from medical operating room surfaces

“…Also, the observed bands at $2366 cm À1 and 1455 cm À1 were ascribed to H-O-H stretching, interpreted as the presence of free (or absorbed) water. 69 Further, the bands detected at 1553 cm À1 correspond to C-H stretching while the peak around 1645 cm À1 corresponds to C]O stretching vibrations. 70,71 The intensity of the absorption bands was reduced aer coating the ZFO NPs with Ag NPs.…”

Eco-Friendly Synthesis, Crystal Chemistry, and Magnetic Properties of Manganese-Substituted CoFe2O4 Nanoparticles

“…Specifically, inverse spinel CFO is one of the most industrially important members of the magnetic ferrite class for device applications . CoFe 2 O 4 is the preferred choice for large data storage and usage in physical (stress) sensors because of higher coercive field and magnetocrystalline anisotropy. , On the other hand, CFO and MnFe 2 O 4 are becoming important for biomedical applications (magnetic resonance imaging, biomolecule detection, and magnetic hyperthermia) due to their increased degree of magnetization compared to other nanoferrites. − The requirements of these applications are achieved by tailoring of the NPs’ magnetic properties, which are known to radically depend on several chemical and physical characteristics, such as particle size, chemical composition, cation distribution, preparation method, surface properties, and interparticle interactions. In this context, the possibility of changing the characteristics of the M­(II) cation within the spinel ferrite is a key to modify magnetic properties.…”
