DESCRIPTION:Speakers: Diaa EL-Rahman Rayan (Central Metallurgical Research
  & Development Institute (CMRDI))\, Mahmoud  Ismail  (Biophysics Branch an
 d Physics Department\, Faculty of Science\, Al-Azhar University\, Nasr Cit
 y\, Cairo\, Egypt)\nIn the present study\, a series of magnetic nanopartic
 les (MNPs) belonging to the spinel ferrite family (XFe2O4 where X = Mg\, C
 u\, Co\, Mn) and hexaferrite structures (Ba2Co2Fe12O22 and BaFe12O19) were
  synthesized using sol-gel and modified co-precipitation methods. The rese
 arch aims to optimize the structural and physical properties for localized
  cancer treatment via magnetic hyperthermia. The structural and morphologi
 cal characteristics were investigated using X-ray diffraction (XRD) and el
 ectron microscopy (FE-SEM/TEM)\, confirming the formation of pure crystall
 ine phases with tailored nanostructures. The optical properties were inves
 tigated using UV-visible spectroscopy\, revealing a significant dependence
  of the energy bandgap on the chemical composition and ion substitution. T
 he calculated bandgap values\, along with the magnetic parameters obtained
  from VSM\, were correlated to the induction heating performance. Under an
  alternating magnetic field (150–300 kHz)\, the specific absorption rate
  (SAR) values reached up to 350 W/g\, particularly in Mn-substituted coppe
 r ferrites.\nFurthermore\, the results indicate that the prepared MNPs\, e
 specially the optimized barium hexaferrite (Ba2Co2Fe12O22)\, exhibit a hig
 h potential for inhibiting tumor cell growth when activated by an external
  magnetic field. These findings highlight the potential of these optimized
  ferrites as high-performance agents for magnetic hyperthermia and multi-f
 unctional biomedical platforms\, offering a promising approach for non-inv
 asive thermal therapy.\nKeywords:\nMagnetic Hyperthermia\; Spinel Ferrites
