Nanoscience and nanotechnology are the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering. The father of nanotechnology, physicist Richard Feynman, describe nanotechnology as procedure that would allow scientists to control and modify specific atoms and molecules. Professor Norio Taniguchi introduced the term "nanotechnology" more than ten years later while researching ultraprecision machining. Modern nanotechnology didn't start until 1981, with the invention of the scanning tunneling microscope, which could "see" individual atoms.

Application on Medicine When applied in medicine, it is called Nanomedicine: In order to reduce the danger of harm to healthy tissue, researchers in nanotechnology are working on a variety of therapies where a nanoparticle can encapsulate or otherwise help to transport drug directly to cancer cells. This may alter how doctors treat cancer and significantly lessen the harmful effects of chemotherapy.

Nanotechnology in Electronics: Simply called Nanoelectronics, You can have smaller, faster, and more portable systems thanks to nanoelectronics. In order to manage and store more data and information, it improves the capacities of electronic devices, components, and integrated systems as well as the density of memory chips. Nanoelectronics can revolutionize many electronic products, applications, and processes, as well as lower their weight, power consumption, and transistor size in integrated circuits. It can also enhance the display screens on electronic gadgets.

Nanotechnology on Consumer products: Scratch-resistant eyewear, crack-resistant paint, anti-graffiti coatings for walls, transparent sunscreen, stain-repellent fabrics, self-cleaning windows, and ceramic coatings for solar cells are all products made with nanoparticles today. Stronger, lighter, cleaner, and "smarter" surfaces and systems can now be made possible. Particle characteristics may alter in unforeseen ways at the nanoscale. The titanium oxide used in sunscreens, for instance, is made of transparent nanoparticles that have the same chemical make-up as the bigger, white titanium oxide particles that have been used in conventional products for decades.

Another example is antimony-tin oxide, which is used as nanoparticles in coatings to give scratch resistance and transparent protection from ultraviolet radiation, which is not possible with bigger size particles. Nanotechnology on Sporting Goods Compared to traditional athletic goods, nano-enhanced goods are significantly more performance-enhancing and superior in terms of strength, stiffness, and durability. Numerous businesses are developing fresher strategies to use nanotechnology to enhance sporting goods even further. To improve their performances, several well-known athletes are choosing to use sports equipment with nanotechnology included. It would be unfair and challenging to evaluate natural athletic talent and human spirit

without providing each competent athlete with the identical sporting equipment because nanoenhanced sporting equipment is an expensive technology. Nanotechnology on Transportation Numerous auto elements, including paint, batteries, fuel cells, tires, mirrors, and windows, can include nanotechnology. The performance of current technologies for the automotive sector is improved by the introduction of nanotechnologies. The main benefits of using nanotechnology in automobiles include the development of lighter and stronger body parts (to improve safety and fuel efficiency), increased fuel efficiency, and consequently improved performance over a longer time. For researchers, the use of nanotechnology in automobiles offers a wide range of options. Nanotechnology can be used to improve the performance, durability, and intelligence of transportation vehicles.

Nanotechnology on Environment Environmental technologies have a lot of potential thanks to nanotechnology. Sensing and monitoring, selective adsorption, and nanomembranes have already seen a lot of success. To combine the demands of the environment with the activity, selectivity, and stability of the nanotechnologies we select, we must be cautious. The high reactivity of nanotechnologies, which is brought on by their sensitive surface and microstructure, accounts for many of their desirable properties, including their high performance. As a result, we must take care to prevent harm to the environment and damage and degradation of nanotechnology.

Issues on Nanotech: Three key factors suggest that nanoparticles are dangerous: Lung harm from nanoparticles is possible. The "ultra fine" particles from incinerators, power plants, and diesel engines can seriously harm a person's lungs. This is due to their size (which allows them to penetrate the lungs deeply) as well as the fact that they bring additional substances, such as metals and hydrocarbons, inside with them. The skin, lungs, and digestive system are three entry points for nanoparticles entering the body. This could contribute to the production of "free radicals," which can harm DNA and cause cell damage. Additionally, there is worry that nanoparticles may be

able to pass through the blood-brain barrier if they are ingested and enter the bloodstream.
