Magnetic Nanoparticles in Tissue Regeneration

Abstract

The remote control operation and manipulation of cells is the prime advantage of magnetic nanoparticles. Control of specific cellular components in vitro as well as in vivo offers a powerful tool for the understanding of cellular functions and molecular signaling to scientist, which helps to develop precise therapeutic applications by clinicians. Cells surface or intracellular labeling by the use of magnetic nanoparticles as an investigation tool in its preliminary stage are successfully developed for the diagnostic and other biomedical applications. Currently, magnetic nanoparticle applications have prominently shifted their focus towards the engineering of cells and their fate in the determination at a molecular level for three-dimensional tissue regeneration. Magnetic force-assisted tissue engineering is often referred to as a "Mag-TE." This chapter is divided into two main sections. The first section presents an overview about the properties, synthesis and structure of magnetic nanoparticles. The second section focuses on how magnetic nanoparticles have been applied in the cell directed tissue engineering and regenerative medicine with potential future prospects.

Comparative Studies on Flotation of Kasolite Using Cationic and Anionic Surfactants

“…b) The free energy of adsorption is large, resulting in lower reagent consumption; c) The electrical charge on the mineral is lower, resulting in better recovery if collector adsorption occurs by exchange or neutral molecule adsorption; and d) The reduced adsorption of collector on bubble surfaces contributes to better recovery of fines. The results are shown in Figs (5,6). This set of experiments was conducted using collector concentration of (1×10 -3 )M and (1×10 -4 )M in case of cupferron and sodium lauryl sulfate respectively, for 120 sec.…”

“…For instance, Tripathi et al, (2013) create a novel floating polymeric-magnetite cryobead for the recovery of hexavalent uranium from the aqueous subsurfaces. The alginate-agarose-magnetite cryobeads were synthesized by the process of cryotropic-gelation at subzerotemperature [6].…”
