NANOTECHNOLOGY is the future. We are heading to a world where almost everything is controlled by technology. So, in this age of cutting-edge technology, every tech company or industry is giving its best to create equipment or technology that will comfort the consumers more than the previous version or product.

In that sense, nanotechnology is way ahead in that competition. For its lightweight, more durability, better electrical conductivity and more other qualities, the nanostructured materials are in a way revolutionizing the tech industry.

What are nano-materials?

Nanoparticles or also called ultrafine particles are particles of matter that have a size of 1 to a few 100 nanometres. As they are really small, they behave differently from bulk materials and they come under the radar of Quantum Mechanics and statistical mechanics. One of the best examples of nanostructured particles is a quantum dot.

What is a quantum dot?

Quantum dots are widely used these days in LED televisions that are providing high definition visuals. The reason for this is that quantum dots are tiny semiconductor nano-particles, and their specialty is that they have some optical and electric properties that make them kind of light emitting particles, which is the big reason they are used in LEDs. They emit that light by absorbing light of one wavelength and converting it to another.

Quantum dots make the motion of conduction band electrons, valence band holes, or excitons confined in all the three spatial directions. A quantum dot possesses a discrete (quantized) energy spectrum.

What are the advantages of nanotechnology?

 When we talk about nano-particles, we are talking subatomic. They may have a very tiny size, but their range and field of benefits are broader than you can imagine.

  • They help enhance and revolutionize innumberable tech companies and industries like transportation, IT (Information Technology), medical sector, energy, electrical gadgets we use in our day-to-day lives, energy and etc.
  • The nano-sized films present in our eye glasses, computer or laptop screens, camera displays can be made residue repellent and water repellent or water resistant, or can be protected like a shield against dangerous Ultra-violet radiations or Infrared radiations.
  • The automobile industry also gains a lot of benefits from this nano-tech as the batteries of the automobiles can be made high power rechargable and highly durable; highly efficient sensors can be used too, also thermo-electric materials for controlling of temperature when required.
  • One of the greatest inventions of human history, transistors, are also getting smaller and smaller as time is passing by. The smaller the transistor, the more data that can be stored in a small space. In the beginning of the century, the size of an usual transistor was 130nm to 250nm. As time progressed, it became 14nm in 2014, by one of world’s leading tech-companies, Intel. Then to beat that IBM (International Business Machine Corporation), one of the leading American computer manufacturers, produced a 7nm transistor just one year after Intel’s 14nm transistor. That wasn’t the end as Lawrence Berkeley National Lab created 1nm transistor, exactly a nanometre size!
  • Smaller transistors make sure the computers can store more and more memory on a single small chip.
  • Doctors are investigating about whether they can use nano-technology to incapsulate medication directly to cancer cells and in this way, they can at least save healthy tissues from getting damaged. It can also be used to decrease or reduce the negative effects of chemotherapy on the patient.

So, nano-technology is really important in the sense that it has the potential to entirely revolutionize the tech industry with its tininess and amazing qualities.
