Nanotechnology involves the studying and working with matter on an extremely small scale. We can categorize one nanometer as one-billionth of a meter (10-9 m) .This is approximately ten times the size of an individual atom or ten hydrogen atoms laid side to side in a single nanometer. Despite its excessively small size, this technology stretches across all diverse branches of science and technology like biology, physics, chemistry, engineering, and materials science. The vast spread of this technology has allowed us in the creation of useful materials, devices, and systems which have started a scientific and technical revolution that are already starting to implement in our daily lives, science and objects used every day. Today nanotechnology is not just a new field of science and engineering, but a new way of looking at matter and studying it.
As mentioned before nanotechnology is used in a wide range of science and technology to improve our lives and make them more efficient. We can see an evident example of the preceding statement in some consumer goods that we use like sunscreens, self-cleaning windows, stain repellent fabrics and bouncy tennis balls. These all have been designed to help us in some way or the other regardless may it be in health or leisure, but the main point here is that all of these are created with the help of nanotechnology to give them the use that they have. For example the tennis ball is covered by a molecular wall consisting of tiny particles that help trap air molecules, thus making the ball extra bouncy. Apart from good that we consume nanotechnology is also being researched in the medical fields where researchers are emerging custom molecular sized nanoparticles that can deliver drugs directly to ...

Nanotechnology is defined as “ a technology executed on the scale of less than 100 nanometers, the goal of which is to control individual atoms and molecules, especially to create computer chips and other microscopic devices” (Webster’s Dictionary, 1999). In the early 1970’s an MIT student by the name of K. Eric Drexler came up with the idea of manufacturing things, both biological and non-biological, from the molecular level up. Drexler noticed the amazing talents of natural biology and wondered if humans could mimic biology on a mechanical level,
Honey I shrunk the technology! It’s not a movie anymore; it’s the direction of global technology. Nanotechnology is this century's equivalent of the Industrial Revolution and it will change everything. The revolution isn’t just around the corner. It has only just begun.
“Nanotechnology is a very fast growing field,” says Huo. “Companies are very interested in people who
Nanotechnology is the manipulation of structures at nano levels. It uses incredibly small materials, devices, and systems to manipulate matter. These structures are measured in nanometers, or one billionth of a meter, and can be used by themselves or as part of larg...

Nanotechnology is defined as the science of design, synthesis and characterization of matter at the nanoscale, which mesures one billionth of the meter [1,2] On that scale, structures exhibit novel chemical, physical and biological properties and processes, which enables the creation of engineered nanomaterials (ENMs), with various characteristics and potential applications. [3] It’s not just that though. Nanotechnology shows the ability to eliminate the gaps among medicine, material engineering and science, computer technology and public policy, creating new clinical and medical approaches to better diagnose, treat and prevent any kind of illness. In fact, it is already moving from simple passive structures
The most exceptional trait about nanomedicine is its capability of eliminating cancers and tumors. Cancers and tumors have been a major problem for people worldwide, from families being torn apart, loved ones vanishing, and much more. Both being a complex matter to challenge as for many years it has been a problem and the closest thing that was thought to be the answer was chemotherapy. Many people have been wanting the actual cure and now we might have the answer. In the article “Nanomedicine”(2014), Guizhi Zhu, Lei Mei, and Weihong Tan establishes that:
Nanotechnology has been a groundbreaking new field of science for years now introducing many new forms of materials stronger, lighter, and more durable than any others before. Nanoscale particles in many things such as the polymer materials for baseball bats, tennis rackets, motorcycle helmets, and power tools can make them work harder than people ever thought, but just like many other things, the better it seems the more consequences it has the potential to have. With all the positives to nanotechnology there will always be a negative, but if regulated correctly can we lessen the downsides of it? Nanotechnology, though it may have a profitable and useful place in the future of our world, how can we engineer it and put it to good use without badly impacting the environmental and the health of people through the advance of it.

Science that deals with study of materials or any particles that is so small and measured in nanometer scale is called “Nanoscience”. Study about very small particles and its chemical and physical changes at nanoscale is not an easy business. Nanotechnology studies the big picture of those small particles, manipulates them to advance new devices and materials. The name “nanotechnology” was created in year 1974 (). But the concept of manipulating Nano particles has been around for centuries mainly in crafting examples are 4th century Lycurgus cup, 13th-18th centuries Damascus saber blades and etc (). Introduction of nanotechnology was to attain multiple benefits to society in many areas like energy production and conservation, pollution clean-up and medicine (). The danger that tags along with this benefiting science does need to be understood before their usage becomes prevalent. Environmental scientists who are concerned about health of organisms and hazard to environment are researching and accessing about toxicity, distribution and fate of the nanoparticles that is released into the environment.
Nanotechnology is a big buzz-word in the realms of science and technology at the moment, and the trend looks set to increase exponentially. All of a sudden, nanotech is everywhere, from computer chips to bicycle frames. But many laymen are unaware of what the term actually refers to. The Wikipedia definition of ‘Nanotechnology’ sums it up as follows:
Nanoscience has developed a lot in modern technologies. A number of nano materials have been synthesized that are being used in different fields in different ways. In biological sciences product of nanobiotechnology has been used as:
Nanotechnology is science, technology and engineering that is conducted at the nanoscale. The nanoscale is about 1 to 100 nanometres.
Nanotechnology is the construction and the use of functional structures designed from an atomic or molecular scale with at least one characteristic dimension measured in nanometers. The prefix "nano" comes from the ancient Greek word for "dwarf". In science it means one billionth (10 to the minus 9) of something. So, a nanometer (nm) is one billionth of a meter, or 0.000000001 meters. A nanometer is about three to five atoms wide, or some 40,000 times smaller than the thickness of human hair. Their special size allows them to significantly improve physical, chemical, and biological properties, phenomena, and processes. Nanotechnology is an exciting area of scientific advancement which promises “more for less”. It offers ways to create smaller, cheaper, lighter and faster devices that can do more and cleverer things while using less raw mat...
