Obtaining and Characterizing a Water-Based Magnetic Fluid

Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

A way of obtaining a biocompatible magnetic fluid and its parameters are described. It is proposed that depolarized dynamic light scattering be used to determine the size of nanoparticles in the fluid phase, and to estimate the aggregative and sedimentation stability of a magnetic fluid upon dilution. It is established that upon the dilution of the magnetic fluid, ellipsoidal aggregates consisting of 20 or more single nanoparticles form in it.
