Investigation of the suitability of zinc-doped cobalt ferrite as hyperthermia heating and MRA contrast agent
Source abstract
Abstract
As a contrast and heating agent, the admissibility of nanoferrites grows gradually. To prepare Co1-xZnxFe2O4, coprecipitation procedure was utilized. The nanoferrites were coated with chitosan. The configuration of spinel ferrite has been verified by XRD spectra and FTIR. Bright- and dark-field TEM and HRTEM were obtained to investigate the surface structure. From EDS analysis, the elemental composition has been determined. The shift of magnetic behavior has been elaborated by the Mössbauer analysis. The change in saturation magnetization and coercivity with zinc proportion has been studied in detail by the M–H curve. The hydrodynamic diameter and polydispersity index (PDI) of the chitosan-coated solution at concentrations 1 mg/ml and 2 mg/ml were measured. An in vitro cytotoxicity test on HeLa cancer cells was investigated. The effect of the contrast agent was investigated by TOF experiments. The heating profile of the samples was examined. It was observed that Co0.6Zn0.4Fe2O4was suitable for hyperthermia applications.Graphical abstract
