“…In order to explain obtained trends, we employed the analysis of MNPs behavior in a non-alternating magnetic eld, by measuring laser transmittance [19][20][21][22][23]. Previously this method gave satisfactory valuable data [15,24]. The analysis was carried out at 30 mT and 400 mT and the results are depicted in Fig.…”

Different phosphates and phosphonates have shown excellent coating ability toward magnetic nanoparticles, improving their stability and biocompatibility which enables their biomedical application. The magnetic hyperthermia efficiency of phosphates (IDP and IHP) and phosphonates (MDP and HEDP) coated Fe3O4 magnetic nanoparticles (MNPs) were evaluated in an alternating magnetic field. For a deeper understanding of hyperthermia, the behavior of investigated MNPs in the non-alternating magnetic field was monitored by measuring the transparency of the sample. To investigate their theranostic potential coated Fe3O4-MNPs were radiolabeled with radionuclide 177Lu. Phosphate coated MNPs were radiolabeled in high radiolabeling yield (> 99%) while phosphonate coated MNPs reached maximum radiolabeling yield of 78%. Regardless lower radiolabeling yield both radiolabeled phosphonate MNPs may be further purified reaching radiochemical purity of more than 95%. In vitro stabile radiolabeled nanoparticles in saline and HSA were obtained. The high heating ability of phosphates and phosphonates coated MNPs as sine qua non for efficient in vivo hyperthermia treatment and satisfactory radiolabeling yield justifies their further research in order to develop new theranostic agents.

“…The behavior of Fe 3 O 4 -DPD MNPs in non-alternating MF (30 mT) for different concentrations is depicted in Fig. 3.The detail explanation of the effect has been described in previous paper 18 , hence only the basic theoretical considerations have been given here. Regardless of the concentration used, at the beginning of the measuring, when the MF is switched-off, the sample has shown the initial transparency.…”

“…The higher concentrations of NaCl lead to increased precipitation of magnetic particles, which makes them difficult to orientate with respect to MF and to create magnetic chains under field effect, as explained previously. 18,[25][26][27][28][29][30][31] The larger aggregation of MNPs due to the presence of electrolyte leads to the increase of magnetic interactions between nanoparticles and magnetic response with respect to the external field is diminished. As a consequence, change in the transparency profile of the sample and decrease of hyperthermia efficiency was observed.…”
