Environmentally-friendly preparation of water-dispersible magnetite nanoparticles

Abstract

Water-dispersible Fe(3)O(4) nanoparticles have been prepared by a simple solution method, in which the particle size (3-11 nm) can be tuned by simply adjusting the reaction temperature and time; the formation mechanism of Fe(3)O(4) nanoparticles is proposed and their low cytotoxicity has also been proved.

Combined toxicity of ferroferric oxide nanoparticles and arsenic to the ciliated protozoa Tetrahymena Pyriformis

“…Fe 3 O 4 NPs was synthesized by typical hydrothermal route as shown in previous reference (Jia et al, 2009). A mixture of anhydrous FeCl 3 (0.324 g, 2.0 mmol), anhydrous CH 3 COONa (0.5 g, 6.0 mmol) and DEG (0.21 mol, 20.0 mL) was heated with constant stirring until a clear solution formed.…”

Spectroscope and molecular model identify the behavior of doxorubicin-SPION binding to bovine hemoglobin

“…Among various types of targeted drug deliverers, nanoFe 3 O 4 has shown great prospect due to its biocompatibility and unique magnetic properties [17][18][19]. Moreover, methods of DOX loaded to iron oxide nanoparticle and its cytotoxicity have been reported [20,21].…”

Multifunctional Manganese Carbonate Microspheres with Superparamagnetic and Fluorescent Properties: Synthesis and Biological Application

“…The layer-bylayer assembly process was monitored by z-potential measurement, which is an effective method for characterization of the surface charge of microspheres. [43] Figure S2 in the Supporting Information shows the z-potentials of bioconjugate. The Fe 3 O 4 @MnCO 3 microspheres are positively charged at neutral pH with a potential of + 8.9 mV, which could be explained by an excess of manganese(II) cations.…”

“…. [43] This could be explained by taking into account the thick MnCO 3 shell surrounding the magnetic cores. Figure 2 B shows photographs of the suspension of Fe 3 O 4 @MnCO 3 in the absence and in the presence of an external magnet.…”
