Abstract

Ultrasound has become a powerful tool in predicting the behaviour of liquid molecules in various environments. Magnetic fluid is a colloidal suspension of magnetic particles in a carrier liquid, stabilized by a surfactant. For biomedical purposes, magnetic particles must be coated with biocompatible substances that ensure their stability, biodegradability and non-toxicity in a physiological medium. The stability and structural properties of some magnetic fluids have been studied by using ultrasonic method. Observed effects are analyzed in the light of the existing studies of magnetic fluids.

Keywords
