Ferrite-based magnetic nanofluids used in hyperthermia applications

► This paper gives a suitable summary and literature survey on the ferrofluids. ► Ferrofluids have an important role in biomedicine and our life. ► Ferrofluids include a magnetic core, surfactant and a liquid medium. ► Nano-ferrites' cores are good candidates for hyperthermia purposes. ► They present a suitable heat generation for hyperthermia.
