“Nanotechnology will let us build incredibly powerful computers. We’ll have more power in the volume of a sugar cube than exists in the entire world.”

As the above quotation stated by Ralph Merkle, nowadays, we could not surprise people with the term nanotechnology because it has become a familiar term. But many people do not even realize the tremendous impact of nanotechnology on our daily lives. Nanotechnology is a contemporary science, engineering, and technology that deals with nanometers.

Engrossing attributes concerning nanotechnology

All the experiments are conducted at the nanoscale (1-100 nanometers) by scientists. To furnish you with a clear example, a single sheet of newspaper is 1,00,000 nanometers thick, and a human hair is in the thickness of 80,000 nanometers. Just imagine scientists are working with just 1-100 nanometers!! A unit nanometer is equivalent to a billionth of a meter.

A unique and striking fact to grasp the discrepancy between nanometer and meter is to pretend earth is a meter, then golf ball is a nanometer. Scientists serve and accomplish at the scale of nanometers to invent new things and features. This technology laid its footprints in various fields and things that are enormously useful to us and the environment. Let's review those domains one over the other. Let’s deep dive into the various fields of nanotechnology!

Environmentally friendly applications

Our ultimate goal is to lessen pollution and to preserve our environment! The significant applications using nanotechnology are wastewater purification using nanobubbles and air purification with ions. It practices two ways to reduce air pollution: Catalysts and nanostructured membranes. Catalysts manufactured from nanoparticles have a wide surface area as they modify vapors escaping from cars and industries into harmless gasses.

On the flip side, Nanostructured materials are under development and can segregate carbon dioxide released from industries and vehicles. Nanobubbles are miniature gas bubbles present in a liquid. They have unique physical properties viz. high internal pressure, longevity, generation of free radicals. Nanobubbles perform an indefinite role in wastewater treatment by performing nanobubble oxidation, surfactant removal, and transfer of hyper-efficient gas.

Nanotechnology in our Lifestyle

Usually, once worn dress will be washed to liquidate the germs and to get rid of the sweat stench. After washing and drying, the dress is to be ironed to remove the wrinkles. But, the above-cited procedures aren't needed for Smart Fabrics. Using Nanotechnology, Smart fabrics or E-textiles have been developed that don’t stain or wrinkle.

Smart Fabrics are water-proof and provide an aesthetic look and feel to the wearers. The most significant characteristic concerning this is they are water repellant. These fabrics protect us from external radiation from the atmosphere and can regulate the temperature of the body. For example, it behaves as a woolen jacket during winter and cotton cloth during the summer season.

Nanotechnology meets the medical field

Nanotechnology plays an inevitable part in the field of medicine, and it is also known as nanomedicine. This feature will revolutionize the way doctors detect and treat diseases in the human body and involve a lot of techniques. In which, the most vital one is the treatment of neurodegenerative disease or cancer. Particles and drugs used in nanomedicine can attack the cancer cells without harming the other healthy cells and allows for earlier detection of disease. Nanotechnology is also used in antibacterial treatments by killing bacteria using Gold nanoparticles and infrared light. Chips consisting of carbon nanotubes attached with the antibodies are used in detecting cancer cells in the bloodstream. Some of the nanoparticles are also being used to enhance pharmaceutical products such as sunscreen.

Electronics with Carbon Nanotubes

First, let’s know about Carbon nanotubes! Basically, they are the allotropes of carbon. They are made up of graphite and constructed as cylindrical tubes with nanometers in diameter. They have the general features and characteristics of silicon. So shortly, they can replace silicon in the field of electronics. Smaller, faster, and more efficient microchips and devices, additionally, lighter, stronger, and more conductive quantum nanowires are also being manufactured by scientists with the help of carbon nanotubes.

Nano Food Technology

Every living organism eats food to survive. We always eat the same sorts of food which depends upon our lifestyle and other provisions. Nanotechnology is also involved in the food industry. The nanostructured food ingredients are being developed by scientists that offer refined taste, texture, and consistency. Nanotechnology will be reducing the wastage of food from microbial injections, as it can prolong the shelf life of each food.

Increasing needs of nanoparticles in food technology include food processing, food packaging, food safety, etc., Nano biosensors can detect the presence of pathogens in food. Nanoclays and nanofilms are the barrier materials employed in food packaging. They inhibit deterioration and oxygen absorption.


Indeed Nanotechnology has some rigorous downsides, its innumerable benefits and applications crack those obstacles like stealing candy from a baby!! "Loving others is how we access true reality and affect every aspect of the university. That is nanotechnology. This is the blueprint to immortality. And its time is now."
