All about Nanotechnology!

What is nanotechnology? Is it related to 0.000000001 of 1-meter length or something else? Read the complete article to know more

Nanotechnology is a very complex and broad subject to discuss. It includes the applications of surface science, organic chemistry, molecular biology, semiconductor physics, energy storage, microfabrication, molecular engineering, Here I will give you a glimpse of the new era technology so that you can be aware of this.





The ideas and concepts behind nanoscience and nanotechnology started by physicist Richard Feynman at an American Physical Society meeting at the California Institute of Technology on December 29, 1959. "Nanotechnology is manipulation of a matter on an atomic, molecular, and supramolecular scale". It involves the ability to see and to control individual atoms and molecules. Everything on Earth is made up of atoms—the food we eat, the clothes we wear, the buildings and houses we live in, and our own bodies.

Tools and techniques:

There are several important modern developments. The atomic force microscope (AFM) and the Scanning Tunneling Microscope (STM) are two early versions of scanning probes that launched nanotechnology. There are other types of scanning probe microscopy. Although conceptually similar to the scanning confocal microscope developed by Marvin Minsky and the scanning acoustic microscope (SAM) developed by Calvin Quate, newer scanning probe microscopes have a much higher resolution, since they are not limited by the wavelength of sound or light.
The tip-point of a scanning probe can also be used to manipulate nanostructures (this process is called positional assembly). Various techniques of nanolithography such as optical lithography, X-ray lithography, dip pen nanolithography, electron beam lithography or nanoimprint lithography were also developed. Lithography is the top-down fabrication technique where a bulk material is decreased/reduced in length to the nanoscale pattern.

A rough working setup of The atomic force microscope (AFM) is shown here-





  • Carbon Nanotubes 
  • Fullerenes and Buckyballs  
  • Fine and Ultrafine Particulates in Air
  • Quantum Dots and Nanocrystals 
  • Titanium Dioxide Nanoparticles 
  • Silver nanoparticles
  • Silver nanowire 
  • Other nano-sized particles


There are many daily uses application like tennis balls to last longer, golf balls to fly straighter, and even bowling balls to become more durable and have a harder surface. 
Clothes and socks have been infused with nanotechnology so that they will last longer and keep people cool in the summer and vice versa. Bandages are being infused with silver nanoparticles to heal cuts faster. Personal computers may become cheaper, faster, and contain more memory thanks to nanotechnology. Also, to build structures for on-chip computing with light, for example, on-chip optical quantum information processing, and nano to picosecond transmission of information.

One application of nanotechnology is employing nanoparticles to deliver drugs, heat, light or other substances to specific types of cells (such as cancer cells). Particles are engineered so that they are attracted to diseased cells only, which allows direct treatment of those cells which decreases the health risk without altering other normal cells. This technique reduces damage to healthy cells in the body and allows for earlier detection of disease. These are just a few application. As mentioned earlier it has very broad application.

The future of nanotechnology can be understood by this demonstrated image, imagine how small it is
