Preparation and inductive heating property of Fe3O4–chitosan composite nanoparticles in an AC magnetic field for localized hyperthermia

Chitosan (or alginate)-coated iron oxide nanoparticles: A comparative study

“…Surprisingly, we found values of maximal saturation magnetization (Ms) as high as 95.1 emu g −1 for iron oxide nanoparticles stabilized with carboxydextran [35], and more usual values such as 52.0 emu g −1 for nanoparticles stabilized with dextran [36]. When the stabilizing polymer was CHI, the Ms values ranged from 20 emu g −1 to 60 emu g −1 [37][38][39]. The presence of maghemite impurities causes a very slight drop in the saturation magnetization of the particles.…”

Biofunctional Composites of Polysaccharides Containing Inorganic Nanoparticles

“…The encapsulation of the nanoparticles using polysaccharides appears as a useful strategy for the biofunctionalization www.intechopen.com of the nanoparticles with adequate targeting moieties. Chitosan (Zhao et al, 2009) and pullulan acetate (Gao et al, 2010) coated magnetic nanoparticles were investigated for magnetic hyperthermia.…”

Electrocatalytic activity of Pt doped TiO2 nanotubes catalysts for glucose determination

“…However, enzymes exhibit a rather slow rate of heterogeneous electron-transfer at conventional electrodes, because of the deep burying of the electroactive prosthetic groups, the unfavorable orientations of enzymes at electrodes [3]. Therefore, the studies are focusing on selecting ideal electrode materials, such as carbon nanotubes [4], iron oxide nanoparticles [5][6][7] and biomaterials [8][9][10] to enhance the direct electrontransfer between the enzymes and underlying electrodes.…”
