Nanotechnology: An Overview!

Nanotechnology | Overview | 26th October 2022 | Virtual Wire



Scientists have always sought and searched for various ways to make technology smaller and portable, this obsession birthed Nanoscience and Nanotechnology.

Nanotechnology is defined as the understanding and control of matter at dimensions of roughly 1-100nm, where unique physical properties make novel applications possible ( Environmental Pollution, 2007). The production of new materials, devices and structures by manipulating matter on a scale of 1-100nm (near-atomic scale). At a particularly given threshold (1-100nm), materials begin to exhibit unique properties that affect the physical, biological and chemical behaviour. Researching, manipulating and developing these unique properties is the essence of nanotechnology.

Application of Nanotechnology


Nanotechnology has a lot of applications ranging from the field of nanomedicine, nanoelectronics, and biomaterials energy production:

  • Electronics and Devices

`With nanotechnology, mobile phones and Televisions have been made flat and sleek from being bulky and heavy. Computer components such as transistors have been made smaller in size, while dangerous materials used in fuse electronics are now replaced with Nanoparticle copper suspension.

  • Medical Field

A wide range of nanomaterials is being used to increase the efficiency of imaging devices and also in reducing the severe side effects of various treatments for chronic diseases like cancer, brain tumour e.t.c

  • Automobile Industry

The automobile industry has become more fluid in applying nanotechnology in making various parts of an automobile. An example is the development of new kinds of batteries that are quicker to charge, more efficient, and light-weighting cars and trucks.

Just to mention a few.
