TL;DR: The results confirm that aqueous suspensions of PEGylated SPIONs are stabilized by steric hindrance over a wide pH range between pH 4 and 10, and the fact that the nanoparticle surface is nearly neutral is in agreement with immunological stealthiness expected for the future biomedical applications in vivo.

Preparation and characterization of narrow sized (o/w) magnetic emulsion
TL;DR: In this paper, the preparation of well-defined magnetic emulsions from an organic ferrofluid is reported, which is composed of superparamagnetic magnetite nanoparticles, with a diameter below 10 nm, stabilized in octane by a surrounding oleic acid layer.

The Preparation of Magnetic Fluids
TL;DR: In any discussion of fluids which have magnetic properties, it is convenient to divide them into the following categories, (A) ferrofluids; (B) magnetorheological fluids; (C) dispersions of micron-sized particles of a non-magnetic material containing magnetic nano-size particles, and (D) fluids containing paramagnetic particles.

Dependence of pH and surfactant effect in the synthesis of magnetite (Fe3O4) nanoparticles and its properties
TL;DR: In this paper, a co-precipitation in an aqueous solution containing ferrous and ferric salts (1:2) at varying pH with ammonia as a base was found to influence the reaction mechanism for the formation of Fe3O4.

Synthesis and characterizations of manganese ferrites for hyperthermia applications
A. Doaga,A. M. Cojocariu,W. Amin,F. Heib,Philipp Bender,Rolf Hempelmann,Ovidiu Florin Caltun +6 more
TL;DR: In this article, the authors focused on MnxFe1−xFe2O4 ferrite particles series with X-ray analysis indicated a crystallite size of the particles in the nanometers domain increasing with the Mn cation substitution level, suggesting that the majority of the nanoparticles are monodomain.

Magnetic Properties of Stable Dispersions of Subdomain Magnetite Particles
Robert Kaiser,G. Miskolczy +1 more
TL;DR: In this article, stable colloidal dispersions of subdomain-size magnetic particles have been prepared that retain their liquid characteristics in the presence of a magnetic field, correcting for the formation of a nonmagnetic surface mantle one unit cell thick.

Methods of Improving the Sensitivity of the Bitter Technique
TL;DR: In this article, a thorough investigation into the nature of magnetite colloids suitable for the Bitter technique has been undertaken, and changes in the method of manufacture are proposed to improve performance.
