The incredible applications of nanoparticles in magnetic energy storage and biomedicine, magnetic recording, and their properties have grabbed everyone’s attention. The continuous research efforts and the work which is being done on the design and fabrication of nanoparticles have made this possible. These particles of less than 5% size are potentially very useful. The small size and dimension of the nanoparticles has a huge application in electronics, bio medical usage, as catalysts and many more.
Listed below are some advantages of nanoparticles:
The small size of the nanoparticles is the best characteristic about it. The small size and surface characteristic makes them different from others.
Due to their tiny size, they can fit anywhere and affect the smallest areas. Therefore, nanoparticles are used for medical purposes also.
The transistors made with the help of magnetic nanoparticles are powerful and energy efficient. The entire memory can easily be stored in a tiny chip.
The smaller size of the nanoparticles is now replacing the voluminous television sets and the computers into handy sets. The brightness of the screens and other features are more attractive than before.
Apart from being smaller in size, nanoparticles are also easy to handle.
Nanoparticles are used as a catalyst to boost the chemical reactions.
Apart from the above general uses of nanoparticles, there are a number of uses of monodisperse nanoparticles. Here, we describe various methods of preparation of nanoparticles and their uses in various fields.
