What is Nanotechnology?

The concept behind Nanotechnology is maneuvering molecules and/or atoms to fabricate resources and formations straightforwardly, in addition to utilizing the exclusive traits of matter at the nano scale (0.1 nm to 100 nm). After that we are at a distinct stage where the term Nanotechnology has been proposed to define this type of human manufacturing procedure.

With the dawn of innovative technologies, things are turning out more competent than before. First, exercise of digital technologies and at the present micro technology is achieving momentum on the complete communiqué. However things do not stop here and additional research is done every day, with the intention of fetching new modernism in the current technologies and to make our lives improved every day. One such kind of technologies is Nanotechnology.

So what is Nanotechnology in reality?

Nanotechnology implies everything tinier than micro technology. Presuming, when we state 'nanosecond', it implies 'billion of a second'. Fundamentally, it functions on molecular stage and will make majority of the things sturdier, lighter and more accurate. The nanotechnology applications are not confined to a specific sector but wraps a complete field of medicine, electronic energy manufacture etc.

History of Nanotechnology

Even though nanotechnology is a moderately modern expansion in scientific study, the progress of its focal ideas took place long back.

The primary usage of the ideas discovered in 'nano-technology' was present there in a seminar given by Richard Feynman, who was a physicist, at an American Physical Society meet at in the year 1959. Feynman defined a progression by which the capability to influence singular molecules and atoms could be developed, making use of singular set of specific apparatus to construct and maneuver another proportionally petite set, and so on downward to the required level. In the track of this, he observed, scaling matters would crop up from the modifying extent of a variety of substantial trend: gravity would turn out to be less significant, surface stress and van der Waals magnetism would turn out to be ever more important, etc. This fundamental concept seemed reasonable, and exponential congregation improves it with parallelism to manufacture a practical magnitude of resultant products.

Why is Nanotechnology Important?

Nanotechnology is playing a very important role today and in the future to change and improve every aspect of human activities. Nanotechnology influences a lot of materials used for manufacturing important items. These materials include biomaterials, ceramics, metals and polymers. The new and improved materials formed through nanotechnology are the source of most important technological advances.

Remarkable Uses of Nanotechnology

Cancer Treatment - Special particles are charged with the use of nanotechnology and are used to treat cancer tumors within the body. These particles move inside the tumor and destroy it permanently. Traditional therapies such as chemotherapy target healthy cells as well whereas nanotechnology cancer treatment has no such side effects.

Sunscreen Lotion - Through zinc oxide particles which have a "nano" size, ultraviolet (UV) rays are absorbed and reflected. As a result, sunscreen lotions appear transparent and are smooth when applied. Earlier, a sunscreen lotion was white and really sticky. Through, nanotechnology, these lotions are more attractive to customers.

Self-cleaning and scratch proof window - This kind of window is actually coated with a special material that has distinctive chemical properties. Once the sun shines on these self-cleaning windows, the material starts to have a chemical reaction and results to breaking down the dirt on it. Also, if there is rain, no droplets are formed. The rainwater is evenly spread on the window panel and it washes away the dirt that was broken down. The nanoscale controls the thickness of the layer.

Stain-repellent cloth or fabric - This is actually a fabric made of dipped woven rolls of cotton fabric in liquid form that has trillions of nanotechnology fibers. The cotton is dried inside an oven that binds these infinitesimal fibers of the cotton thread. As a result, the fabric becomes resistant to liquid although its physical appearance does not change.

Bouncing tennis ball - These balls are specially coated with a nano-sized material. The molecular barrier of the ball that formed because of these minute particles traps the molecules of air, thus, making the tennis ball bouncier.


In the future, nanotechnology can change the theories and applications we believe and use. The fields of manufacturing, information technology, electronics and communications have very advance future if nanotechnology is further enhanced.
