“…Fig. 2 shows the FT-IR spectra of naked magnetic nanoparticles (MNP) (a mean size about 8 nm) [29], CA-MNP (a mean size about 30 nm with 11 nanoscale coatings) [30], CMCH-MNP (a mean size about 24.5 nm with 8 nanoscale coatings) [31] and CD-MNP (a mean size about 50 nm with 21 nanoscale coatings) [32] in the 300 cm −1 to 2000 cm −1 wave number range. By comparing the FT-IR spectra of the Fe 3 O 4 powders, we can see the band of Fe-O in tetrahedral structure, whose characteristic absorption is 585 cm −1 .…”

Monodispersed Fe3O4 magnetic particles adsorbed by amylase (such as citric acid (CA), carboxymethyl chitosan (CMCH) and β-cyclodextrin (CD)) were prepared by means of co-precipitation method. The absorption character of the samples was investigated by FT-IR, TG and VSM. It was found that the carboxyl (COOH groups) of amylase reacted with the hydroxyl (OH groups) on the surface of Fe3O4 particles, resulting in the formation of iron carboxylate that was adsorbed onto Fe3O4. The induction heating properties of the magnetic Fe3O4 nanoparticles in an alternating current magnetic field were also investigated and the thermo-magnetic stability in induction heating was discussed.
