How Tiny Magnets Could Change Medical Treatments

Scientists have been exploring the use of tiny magnetic particles mixed with blood to improve heat transfer and potentially revolutionize medical treatments. These nanofluids, specifically Fe3O4/blood and CoFe2O4/blood, are being studied for their ability to enhance thermal conductivity and efficiency. The research focuses on how these nanofluids behave on an exponential surface under the influence of a magnetic field, thermal radiation, and convective heating. This isn't just about getting hotter; it's about precise control of heat, which is crucial for medical applications like hyperthermia treatment, where targeted heat can help in fighting diseases. Fe3O4/blood nanofluids show higher thermal efficiency compared to CoFe2O4/blood. This is due to stronger concentration and radiation effects. When subjected to an intense magnetic field and convective heating, both types of nanofluids show significant thermal improvements, making Fe3O4 a promising candidate for magnetic hyperthermia and controlled thermal treatments. Interestingly, the shear drag in CoFe2O4/blood diminishes more rapidly than in Fe3O4/blood. This is attributed to the enhanced magnetic field and the stretching of the surface. These findings highlight the potential of Fe3O4 nanofluids for applications where efficient heat transfer is essential, such as in biomedical systems and thermal management. The study suggests that these nanofluids could pave the way for new hemodynamic systems and advanced drug targeting methods. The ability to control heat precisely could lead to more effective and targeted treatments, reducing side effects and improving patient outcomes.
