Nanotechnology and Nanoscience are closely related terms. Nanotechnology is the study and application of extremely small things. It is the engineering of functional systems at the molecular scale. It is the future of science and technology.

The whole idea of Nanotechnology developed over a long period of time. It is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced.

The father of nanotechnology is Heinrich Rohrer. Eric Drexler developed and popularized the concept of nanotechnology and founded the field of molecular nanotechnology. It is being used in developing countries to help treat disease and prevent health issues. It’s hard to imagine just how small nanotechnology is. So, here are some examples to clear your doubts:

  • There are 25,400,000 nanometers in an inch
  • A sheet of newspaper is about 100,000 nanometers thick
  • On a comparative scale, if a marble were a nanometer, then one meter would be the size of the Earth

Application of Nanotechnology

Some of the areas where it is used are as follows-

  1. Electronics
  2. Food
  3. Fabric
  4. Agriculture
  5. Fuels
  6. Air and Water treatment


It reduces power consumption while decreasing the weight and thickness of the screens.


Companies are using nanomaterials that will make the difference in food. It will lead to an impact on several aspects of food science.


It allows the improvement of fabric properties without a significant increase in weight, thickness, etc.


It includes delivery of agrochemicals and nutrition, pesticides, fisheries and detection of nutrient deficiencies.


It can fulfill the shortage of fossil fuels such as diesel and gasoline by making the production of fuels from low-grade raw materials.

Air and Water treatment

It includes the removal of industrial wastes, such as a cleaning solvent called TCE, from groundwater.

So, we have learned about the applications of nanotechnology. Now, here are some pros and cons of nanotechnology.


  • It replaces toxic components and uses less energy.
  • It can also benefit the energy sector.
  • Can be used in medical purposes.


  • It leads to lack of employment in many sectors.
  • It is expensive and its cost is increasing day by day.
  • Increases the chance of health issues.

So, these are some pros and cons of nanotechnology.
