In this study, superparamagnetic Fe 3 O 4 nanoparticles were individually prepared with one of three polysaccharides as stabilizer, i.e. soluble starch, carboxymethyl cellulose sodium (CMC) and agar. Since polysaccharides present the dynamic supramolecular associations facilitated by inter- and intra-molecular hydrogen bonding, they can act as templates for the growth of nanosized...
Films made of agar and potato starch were elaborated and tested for a potential use as food packaging. Fourier-transform infrared spectroscopy (FT-IR) confirmed that starch and agar were compatible and inter-molecular hydrogen bonds existed between them. Scanning electron microscopy (SEM) of composite film with 15% content of agar showed a compact and homogeneous structure. X-ray diffraction (XRD)...
