Editing Ferrofluid (section)

====Medical applications====
Ferrofluids have been proposed for magnetic drug targeting. In this process the drugs would be attached to or enclosed within a ferrofluid and could be targeted and selectively released using magnetic fields.<ref>{{cite journal|last1=Kumar|first1=CS|last2=Mohammad|first2=F|title=Magnetic nanomaterials for hyperthermia-based therapy and controlled drug delivery|journal=Advanced Drug Delivery Reviews|date=14 August 2011|volume=63|issue=9|pages=789–808|pmid=21447363|pmc=3138885|doi=10.1016/j.addr.2011.03.008}}</ref>

It has also been proposed for targeted [[magnetic hyperthermia]] to convert electromagnetic energy into heat.<ref>{{cite journal|last1=Kafrouni|first1=L|last2=Savadogo|first2=O|title=Recent progress on magnetic nanoparticles for magnetic hyperthermia|journal=Progress in Biomaterials|date=December 2016|volume=5|issue=3–4|pages=147–160|doi=10.1007/s40204-016-0054-6|pmid=27995583|pmc=5304434}}</ref>

It has also been proposed in a form of nanosurgery to separate one tissue from another—for example a tumor from the tissue in which it has grown.<ref name=app>{{cite journal|author1=Scherer, C.  |author2=Figueiredo Neto, A.
