Abstract

Fe3O4 nanoparticles in aqueous suspensions are not stable but aggregate, tremendously changing the spectra of their biomedical applications. A modified version of the Dynamic Light Scattering (DLS) setup experiment was used to monitor Fe3O4 nanoparticle aggregation in aqueous diluted suspension. The experimental setup and the data processing procedure is described in detail and the variation of the average aggregate diameter in time is presented in this work.
