Conventional drug treatment for breast cancer, chemotherapy would destroy the cancer cells because of the medicine targeting rapidly dividing cells. However, healthy cells and tissues in blood, mouth, intestinal tract, nose, nails, vagina and hair also divide rapidly, and get damaged. Hyperthermia therapy refers to body temperature elevated to damage cancer cells. It is usually utilized with different types of tumour treatment, for example, radiation treatment and chemotherapy. In hyperthermia, different kind of energy might be utilised to apply heat, including microwave, laser, ultrasound and magnetic fields. Super paramagnetic iron oxide nanoparticles (MNPs) show a number of interesting properties which can be utilised in various biomedical applications which include MRI (magnetic resonance imaging), repairing of tissues, cell separation, hyperthermia and drug delivery .

Magnetorheological fluid is one of the smart materials. There are various excellent features of MR fluids such as adjustable viscosity, fast response time when exposed to magnetic field, ability to work in different temperature gradient, simple interface between electrical power input and mechanical power output, precise controllability of MR fluids makes the MRF technology attractive and feasible for many applications and has also been employed successfully in various applications. Latest application of Magnetorheological fluids are in the field of thermal engineering, MR fluids are used in refrigerators, ovens etc, and the heat transfer techniques of fluids is used to provide heating or cooling. In these appliances if heat transfer is controlled, then there will be automatic decrease in energy consumption..
