With the onset of the use of nanotechnology, the whole technical field revolutionized tremendously. From building super-compact and highly-efficient devices to its use in advanced surgeries, nanotechnology made problem-solving easier. In this module, we’ll be focusing on some of the best applications of nanotechnology. But before that, a quick definition of nanotechnology.

Nanotechnology is the field of science which focuses on the understanding, and the manipulation of matter at the atomic and molecular scale. It takes in the use of engineering, medical, robotics as well as computing, etc. for attaining precise results.

Application of Nanotechnology    

  • Energy Sectors
    With the use of nanotechnology highly-compact and energy-efficient energy manufacturing, transferring and storage devices have been manufactured. For example, nanotechnology has been used in the development of compact solar cells, which in turn is used to construct highly energy-efficient solar panels which are smaller in size. Thus reducing the overall manufacturing cost, making it more economical.

  • Medical Sectors

    There has been a massive implementation of nanotechnology in the medical field. Nanobots are now being injected into the patient’s body for precise identification and removal of all sorts of blockages. Surgeries which earlier took several hours manually can now be completed within minutes using nanotechnology.

  • Defense Sector
    With the help of nanotechnology, advanced weaponry can be constructed like super-precise missiles which can locate and hit targets with great accuracy without any additional casualties. Also, developing smart bullets which can be remotely controlled and used to hit specific targets with any civilian casualties.

  • Space Technology
    Nanomaterials are used in the manufacture of lightweight yet highly durable spacecraft which will reduce the overall cost and make space missions more economical.

  • Packaging Sectors

    Nanomaterials are now used in the food packaging industry, which helps in preserving the food items for a longer duration, thus improving the overall safety standards.

Many benefits of nanotechnology depend on the fact that it is possible to tailor the structures of materials at extremely small scales to achieve specific properties, thus greatly extending the materials science toolkit. Using nanotechnology, materials can effectively be made stronger, lighter, more durable, more reactive, more sieve-like, or better electrical conductors, among many other traits. Many everyday commercial products are currently on the market and in daily use that rely on nanoscale materials and processes:

  • Nanoscale additives to or surface treatments of fabrics can provide lightweight ballistic energy deflection in personal body armor, or can help them resist wrinkling, staining, and bacterial growth.
  • Clear nanoscale films on eyeglasses, computer and camera displays, windows, and other surfaces can make them water- and residue-repellent, antireflective, self-cleaning, resistant to ultraviolet or infrared light, antifog, antimicrobial, scratch-resistant, or electrically conductive.
  • Nanoscale materials are beginning to enable washable, durable “smart fabrics” equipped with flexible nanoscale sensors and electronics with capabilities for health monitoring, solar energy capture, and energy harvesting through movement.
  • Lightweighting of cars, trucks, airplanes, boats, and space craft could lead to significant fuel savings. Nanoscale additives in polymer composite materials are being used in baseball bats, tennis rackets, bicycles, motorcycle helmets, automobile parts, luggage, and power tool housings, making them lightweight, stiff, durable, and resilient. Carbon nanotube sheets are now being produced for use in next-generation air vehicles. For example, the combination of light weight and conductivity makes them ideal for applications such as electromagnetic shielding and thermal management.
