Ferrofluid is a liquid that is attracted to the poles of a magnet. It is a colloidal liquid made of nanoscale ferromagnetic or ferrimagnetic particles suspended in a ...
Ferrofluidic seals rely on the general principle of ferrofluids - fluids that display magnetic attraction.Following research on ferrofluids during the 1960s, the ferrofluidic seal was first patented in 1971 by R.E. Rosensweig (USP 3,620,584), who subsequently founded Ferrofluidics Corporation with R. Moskowitz.

A ferrofluid mirror is a type of deformable mirror with a reflective liquid surface, commonly used in adaptive optics. It is made of ferrofluid and magnetic iron particles in ethylene glycol, the basis of automotive antifreeze. [1] The ferrofluid mirror changes shape instantly when a magnetic field is applied.
Ferrofluid on glass, with a rare-earth magnet underneath. A rare-earth magnet is a strong permanent magnet made from alloys of rare-earth elements.Developed in the 1970s and 1980s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets.
Another application of magnetic nanoparticles is in the creation of ferrofluids. These are used in several ways. Ferrofluids can be used for targeted drug delivery in the human body. [78] The magnetization of the particles bound with drug molecules allows "magnetic dragging" of the solution to the desired area of the body.
An important task in cancer research is developing more precise methods for delivery of medicine to affected areas. One method involves the binding of medicine to biologically compatible magnetic particles (such as ferrofluids), which are guided to the target via careful placement of permanent magnets on the external body.
Fionn Ferreira, whose full name is Fionn Miguel Eckardt Ferreira, [4] was born in Cork to boat-builder and modeller Anne Eckardt, from Germany and West Cork, [5] and boat-builder Rui Ferreira from Portugal, who had met in the UK in 1994 and settled in Ballydehob, County Cork.
