“…In this sense, and motivated mainly by the excellent manageability, flexibility, and transparency20 of the polymeric materials, a significant amount of research has been focused on the incorporation of magnetic nanoparticles into polymeric matrices. For this case, different methods can be used, for example, nanoparticles can be synthesized in situ inside the polymeric matrix21 that usually have functional groups that can form coordination bonds with metallic ions 22. In a recent work,23 it has reported that the synthesis of ZnS nanoparticles with a blende structure and a particle size in the range of few nanometers are well dispersed in the sodium carboxymethyl cellulose (Na‐CMC) films.…”

A magnetic hybrid material (MHM), consisting of iron-oxide nanoparticles (~4 nm) embedded in sodium carboxymethyl cellulose (Na-CMC) matrix was synthesized. The MHM synthesis process was performed in two stages. First, a precursor hybrid material (Fe(II)-CMC) was synthesized from two aqueous solutions: Na-CMC solution and FeCl 2 solution. In the second stage, the precursor hybrid material was treated with H 2 O 2 under alkaline conditions to obtain the MHM. The results obtained from X-ray diffraction show that the crystalline structure of iron oxide into MHM corresponds to maghemite or magnetite phase. Conversely, the results obtained from Fourier transform infrared (FTIR) spectroscopy reveal that the polymeric matrix (Na-CMC) preserves its chemical structure into the MHM. Furthermore, in FTIR spectra are identified two characteristic bands at 570 and 477 cm À1 which can be associated to maghemite phase. Images obtained by high resolution transmission electron microscopy and bright field scanning transmission electron microscope show that iron-oxide nanoparticles are embedded in the Na-CMC. Magnetic properties were measured at room and low temperature using a quantum design MPMS SQUID-VSM magnetometer. Diagrams of magnetization versus temperature show that iron-oxide nanoparticles embedded in Na-CMC have a superparamagnetic-like behavior.

“…As shown in ( Figure 2 b), a band appears at 1683 cm −1 and may be assigned to C = N stretching which confirms the presence of crosslinking between casein and glutaraldehyde. In (Figure 2 c) the appearance of peaks around 450 and 480 cm −1 may be assigned to Fe–O bonds of magnetite, which are characteristic peaks of iron oxide (e.g., polyhedral Fe 3+ –O 2− )stretching vibrations of iron oxide, and thus confirm the impregnation of iron oxide into the matrix of casein nanoparticles [ 13 , 14 ].…”

Iron oxide impregnated casein nanoparticles (IOICNPs) were prepared by in-situ precipitation of iron oxide within the casein matrix. The resulting iron oxide impregnated casein nanoparticles (IOICNPs) were characterized by Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FTIR), Vibrating sample magnetometer (VSM) and Raman spectroscopy. The FTIR analysis confirmed the impregnation of iron oxide into the casein matrix whereas XPS analysis indicated for complete oxidation of iron (II) to iron(III) as evident from the presence of the observed representative peaks of iron oxide. The nanoparticles were allowed to swell in phosphate buffer saline (PBS) and the influence of factors such as chemical composition of nanoparticles, pH and temperature of the swelling bath, and applied magnetic field was investigated on the water intake capacity of the nanoparticles. The prepared nanoparticles showed potential to function as a nanocarrier for possible applications in magnetically targeted delivery of anticancer drugs.

“…The obvious spectral differences between pure PPy and the composites indicate that PPy exhibits a different chain structure, and there are physicochemical interactions between the nanoparticles and PPy. The presence of iron oxide nanoparticles in the composite is strongly supported by the new peaks at 485 cm À1 and 588 cm À1 as shown in Figures 12.4c and d, which are due to the stretching vibrations of iron oxide [74]. This observation indicates that a magnetic nanocomposite can be synthesized with PPy if polymerization is achieved in a short period of time.…”
