The interaction of iron oxide nanoparticles obtained in acoustoplasma discharge with cavitation with blood plasma fibrinogen is studied in a model solution by dynamic light scattering. Depending on the storage time of the nanoparticles, their interaction with the protein shows different dynamics of the size distribution. However, the biological action of the nanoparticles is the same action regardless of the storage time-they act as inhibitors of the fibrin gel formation reaction.
