Biomedical Applications

of Ferrofluid


Ferrofluid, also referred to as magnetic liquid, or magnetic fluid, is a colloidal liquid which contains tiny magnet iron oxide particles that are suspended in a carrier fluid. It is used in science, art, as well as biomedicine in a range of ways.

It is used to create liquid seals which are utilized for computer hard drives and liquid seals that seal moving parts. There are also applications for it in the field of liquid robotics. In future biomedicine, ferrofluids will be used to transport drugs to the appropriate location within the body. They can also serve as a contrast agent in MRIs.

Nanoparticles of these can be employed to decrease the adverse negative effects of conventional treatments for cancer. They can also be utilized together with heat therapy to treat tumors. However, they aren’t able to heat in real tissue the same way as the laboratory tests.

Liquid robotics is one of the most interesting applications of ferrofluids. Jitka Cejkova, a chemical robotics researcher, has taken the inspiration of living cells in order to design an organic robot that operates with non-magnetic droplets. She’s not a fan of using ferrofluid in biological tissues, however.

Ferrofluid can be used to create high-purity nylon and polyester. Its processing is highly efficient and precise. It was used to create the corrective lens for the Hubble Space Telescope.

The use of ferrofluids for biomedical uses has grown in recent years. They have been used to kill parasites and remove tumors. They are being employed to treat prostate cancer. In February, a US study of the drug called Nanotherm in prostate cancer patients revealed positive results.
