摘要：

Potential medical applications of ferromagnetic fluids whose nanoparticles are coated with biological substances, has stimulated the search for magnetic fluids of new properties. In this study the effects of double biocompatible coating of ferromagnetic nanoparticles on the properties of the ferrofluid subjected to an external magnetic field have been studied by the ultrasound method. The ultrasound wave absorption coefficient values measured have proved a good structural stability of dextran and polyethylene glycol magnetic fluids with its particles covered with two surfactant layers.
