“…The applications of nanomaterials in the biomedical field allows solving many issues such as targeted drug delivery [ 1 , 2 ], contrast-enhancing dye in magnetic resonance imaging (MRI) [ 3 , 4 , 5 , 6 , 7 , 8 ], mediators for hyperthermia applications [ 9 , 10 , 11 , 12 , 13 , 14 ], cell labeling and tracking [ 15 ], angiography with MRI [ 16 , 17 , 18 ], cellular transfection using magnetic fields [ 19 ], cerebral blood volume (CBV) experiments of functional MRI (fMRI) [ 20 ], drug distribution in the brain [ 21 ], and antimicrobial activity agent [ 22 ]. Surface functionalized/modified spinel ferrite nanoparticles such as MnFe 2 O 4 , MgFe 2 O 4 , CoFe 2 O 4 , ZnFe 2 O 4 , Fe 3 O 4 are excellent mediators for cancer thermotherapy and MRI contrast agents [ 23 , 24 , 25 , 26 , 27 ].…”
