Abstract
To be able to use magnetic fluids (MF) in medical applications, the magnetic nanoparticles suspended in the fluid must be coated with a substance, which would ensure their stability, biodegradability and nontoxicity in a physiological medium. An important application in biomedicine is magnetic fluid hyperthermia, offering a possibility to increase the tumour temperature to 41-46\degC to kill tumour cells. In the work, the influence of the surfactant on the heat effect has been studied. Tables 1, Figs 5, Refs 11.
