An aqueous suspension containing magnetic nanoparticles is not stable because the nanoparticles aggregate. As the aggregates
size increases and the number of particles in suspension decreases, the rheological properties of the nanofluid, which are important for
biomedical applications, change tremendously. Modified versions of the SLS and DLS experiments were used to monitor the nanoparticle
aggregation and the results are presented in detail.
