    The most significant challenge related to the formulation of MNP suspension is the occurrence of particle agglomeration. Agglomeration is a process in which the individually dispersed particles are clumped into a single cluster. Agglomeration starts with the formation of doublets, which later on grow into triplets, quartet, and so forth.

  • Biomedical applications for magnetic nanoparticles

    Magnetic nanoparticles can stick together if they collide. This can lead to agglomeration, which is generally detrimental for applications. In order to prevent agglomeration, nanoparticles are often coated with some material to prevent agglomeration (either because of steric or electrostatic effects). Organic surfactants. Normally long chain
