There are many applications of nanomaterials or nanoparticles. We have already discussed the various properties of nanomaterials. Based on these unusual properties, there are many applications of nanomaterials. Today we will discuss the magnetic and medicinal properties.
a) High Power Magnets. Nanotechnology has application in making of high power magnets. Magnets made of nanocrystalline yttrium-samarium-cobalt grains possess very unusual magnetic properties due to their extermely large surface area. The main applications for these high-power rare-earth magnets include quieter submarines, automobile alternators, land-based power generators, and motors for ships, ultra-sensitive analytical instruments, and magnetic resonance imaging (MRI) in medical diagnostics.
a) Researchers are developing customized nanoparticales the size of molecules that can deliver drugs directly to diseased cells in our body. When it’s perfected, this method should greatly reduce the damage treatment such as chemotherapy does to a patient’s healthy cells.
b.) Nanomedicine refers to future developments in medicine that will be based on the ability to build nanorobots. In the future these nanorobots could actually be programmed to repair specific diseased cells, functioning in a similar way to antibodies in our natural healing processes.
