Uses of Magnetic Nanoparticles in Medicine and Data Storage
When it comes to the use of nanoparticles in applications of any novel sort, these particles possess many properties such as magnetic, electrical, chemical, and so on. Magnetic Nanoparticle are defined as nanoparticles, which get magnetised in the presence of an external magnetic field or simply put are paramagnetic in nature. Magnetic nanoparticles can be manipulated in a number of ways owing to their super-paramagnetic properties, which is their tendency to get strongly magnetised.
High densities of storage can be achieved through these particles owing to their nano-scale and high value of magnetisation. They can also be focused and used to deliver drugs at a controlled pace. This is why magnetic nanoparticles have become extremely popular in the medical and data storage technologies.
Three major types of magnetic nanoparticles are being widely used in industry these days. They are Ferrite based, metallic and metallic with coating or shell. Ferrite based nanoparticles are used primarily in electronics and data storage whereas metallic nanoparticles coated with oxides or enzymes are used in medical diagnoses and treatment. Many Manufactures produces high quality magnetic nanoparticles of all the above stated three types and also many more novel varieties.
Uses in Medical Science
Magnetic nanoparticles will soon entirely replace conventional diagnosis labels such as radio-isotopes. These nanoparticles can be conjugated or coated with enzymes, carbohydrates or proteins so as to cling on to antibodies or antigens. This helps in detection of pathogens. Cancer cells can also be removed from the blood stream by manipulating magnetic nanoparticles.
Researchers along with magnetic nanoparticle manufacturers are also working on applications of these particles in resonance imaging, genetic engineering and treatment of waste water.
Uses in Data Storage Devices and other Electronics
Magnetic nanoparticles have proved to be beneficial in development of unique sensors. These sensors owe their small response time to the unparalleled magnetic properties of the nanoparticles. Sensors for detection of cracks and defects in industrial machinery have also utilised magnetic nanoparticles, especially cobalt based and iron oxide based magnetic nanoparticles.
High data storage densities have been achieved through the use of anisotropic crystals densely packed magnetic nanoparticles. This has brought about the second revolution in data storage technology after the one initiated by semiconductors such as Silicon.
