Mössbauer analysis and induction heating evaluation of grapes like FZ@MWCNT towards cancer treatment

Abstract We have successfully modified the synthesis of γ-Fe2O3 and ZnO in a variety of potential matrices, like as multiwall carbon nanotubes (MWCNT) and graphene oxide (GO), referred to as FZ@MWCNT and FZ@MWCNT-GO. X-rays diffraction (XRD) and scanning electron microscopy (SEM) were performed for phase formation and morphological analysis. Phase purity and superparamagnetic environment of maghemite and FZ@MWCNT were investigated by 57Fe Mossbauer spectrometry at 77 and 300 K which further confirm the reduction of dipolar interaction. Induction heating of γ-Fe2O3, FZ@MWCNT and FZ@MWCNT-GO were analysed at various concentrations of nanoparticles to investigate the suitability of this nanocomposite for hyperthermia application. Ironically, the inductive heating rate of FZ@MWCNT at 3 mg/ml concentration is reflecting their high potential for hyperthermia therapy in cancer treatment.
