The Acoustic Spectroscopy of Biocompatible Fluid in a Magnetic Field

The utilization of magnetic nanoparticles in the area of medicine is able because of their biocompatibility, non-toxicity, and common use in several medical applications. Biocompatible magnetic fluids are used for diagnostics and therapy in medical applications, in pharmacy, and in biosensors. These fluids are used as a delivery system for anticancer agents in a locoregional tumor therapy-magnetic drug targeting and hyperthermia. The water-based magnetic fluid is constituted by coating the small magnetic nanoparticles with oleic acid and further dispersion in water. For the study of the influence of an external magnetic field on the aggregation processes of magnetic nanoparticles in biocompatible magnetic fluids, acoustic spectroscopy as a useful tool was used. The goal of the article is to bring new information about the creation of structures in the presence of different application processes of magnetic fields and the temperature of the investigated biocompatible fluid.
