Graphene oxide (GO) based composite systems have been fabricated and investigated as a novel electroresponsive electrorheological (ER) dispersed phase because of their proper electrical conductivity and polarizability for their ER application, in addition to graphene composites. This paper briefly reviews mechanisms of the fabrication of various graphene and GO based composites and their critical ER characteristics including flow curve, yield stress, and dynamic properties measured using a rotational rheometer. Relaxation time and achievable polarizability from dielectric analysis using a LCR meter are also discussed.

“…Again, paramagnetism was observed, since Tb-based magnetic glass particles were used in a similar approach to Gao et al 25 Alternatively, Pacurariu et al synthesized -Fe2O3/SiO2 core shell NPs as possible candidates for magnetic paper pigments. 27 A SiO2 shell coated on a -Fe2O3 core helped improve the whiteness of the particles, with the cost of a reduction in the saturation magnetization (Ms = 0.8 emu/g). However, only magnetic NPs were studied in this work, and magnetic papers were not fabricated.…”

“…Due to the wide potential of applications in various fields, such as biotechnology, biomedicine, magnetic fluids, catalysis, magnetic data recording and storage media, magnetic resonance imaging, magnetic fluid hyperthermia, magnetic drug delivery, cell separation, magnetic paper and more recently in environmental protection, magnetic iron oxide nanoparticles (M-IONPs) are the main components of the modern technology [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. In nature, many forms of iron oxides are found, but the most technologically used are the magnetite (Fe 3 O 4 ), maghemite (γ-Fe 2 O 3 ) and hematite (α-Fe 2 O 3 ) (Figure 1).…”

The broad area of magnetic iron oxide nanoparticle (M-IONP) applications and their exclusive physico-chemical characteristics (superparamagnetic properties per se, solubility and stability in aqueous solutions, and high bioavailability in vivo) make these nanoparticles suitable candidates for biomedical uses. The most employed magnetic iron oxides in the biomedical field are magnetite and maghemite. Cancer represents a complex pathology that implies multiple mechanisms and signaling pathways, this complexity being responsible for the increased resistance to therapy and the lack of an effective curative treatment. A potential useful alternative was considered to be the use of magnetic iron nanoparticles. The M-IONPs proved to be effective as contrast agents in magnetic resonance imaging, as drug delivery carriers for different therapeutic agents, in magnetic cell separation assays, and are suitable to be engineered in terms of size, targeted delivery and substance release. Moreover, their in vivo administration was considered safe, and recent studies indicated their efficiency as anticancer agents. This chapter aims to furnish an overview regarding the physico-chemical properties of M-IONPs (mainly magnetite, maghemite and hematite), the synthesis methods and their in vitro biological impact on healthy and cancer cell lines, by describing their potential mechanism of action-enucleation, apoptosis or other mechanisms.
