Medical Applications of Ferrofluid
What exactly is ferrofluid? This is a colloidal mixture consisting of nanosized ferrromagnetic particles that are suspended within a carrier fluid. The particles are coated with a surfactant to prevent the clumping of. Ferrofluid is useful in a myriad of ways such as dentistry, medicine and even the environment. But, it is to be kept in mind that ferrofluid isn’t a substitute for aqueous solution.
Ferrofluid is a type of magnetic suspension nanoparticles. The diameter of ferrofluid is generally one billionth of a millimeter. Brownian forces that are in opposition to gravity-induced agglomeration, keep the particle from collapsing. Van der Waals forces as well as magnetic dipole interaction encourage an agglomeration. Ferrofluids typically comprise ferrite nanoparticles that have dimensions of 10 nanometers. They are coated with surfactants that prevent the particles from clumping and aids in maintaining stability.
Ferrofluids that contain antibodies are utilized in the field of immunomagnetic separation, cell sorting, and gene therapy. Antibodies assist the ferrofluids in binding to their cells of choice and then magnetically separate them. There are numerous industrial and commercial uses for ferrofluids that contain antibodies. NASA scientists also created the material. The ferrofluids might one day be used to transport medications throughout the body. Research on ferrofluids has been restricted to industrial uses. However, medical benefits may be possible.
Magnetic nanoparticles are also employed to transport drugs for targeted cancer therapy. The use of magnetic nanoparticles when combined with heat and magnetic fields allow medication to be delivered to certain regions of the body, and lessen the negative side effects of conventional treatments for cancer. Combining magnetic fields with heat can treat deep-seated cancers. A 28-year-old Caucasian male developed discoloration on his hand following having taken ferrofluid.
Ferrofluids are composed of liquids that contain magnetic particles suspended within them. They are also referred to as magnetic colloids. In the early 1960s, two different NASA laboratories and the AVCO Space Systems company independently developed ferrofluids. They are composed of microscopic particles of magnetite, iron, and cobalt suspended in an aqueous. Their size is between three and fifteen nanometers and they are in an Brownian motion when they are away from the magnetic field. The magnet pulls the liquid around to make it an solid.
Since the field of ferrofluids has advanced and they have discovered a variety of commercial applications and new ways to use them. Since their beginning, they have been used to create seals and speakers. They are also used to create superparamagnetic composites as well as medical imaging. Ferrofluids possess magnetic properties that are similar to liquids, but they are extremely stable. Apart from the scientific applications, ferrofluids have also become economically viable and are considered a nanomaterial of repute.
Developed by NASA scientist Steve Papell, ferrofluids are beneficial in a variety of industrial applications, from computers to space exploration. These liquids are self-assembled into needle-like points, and then release a stream of particles that could eventually be used as satellite thrusters. If it is accepted as a standard in the production of computer chips, it can be employed in a variety of applications. Its chemical composition as well as its the ability to be used in a variety of ways make it appealing to many industries.
