Nanotechnology (often abbreviated nanotechnology) is the use of matter at an atomic, molecular and supramolecular scale for industrial purposes. It is science and technology to manipulate the structure of matter at the molecular level. In a lecture by physicist Richard Feynmans, he described the process by which scientists can manipulate and control individual atoms and molecules.
Nanotechnology is a term for the field of scientific and technical phenomena on the nanometer scale that occur and are used in the construction, characterization, manufacture and application of materials, structures, devices and systems. The earliest and most widely used descriptions of nanotechnology related to a specific technological goal of manipulating atoms and molecules to produce macroscale products, now called molecular nanotechnology. In the natural world, there are many examples of nanoscale structures (called nanoscale ) including essential molecules in the human body and components of food. Many technologies have studied nanoscale structures for many years, but it was only in the last quarter of the last century that it was possible to modify molecules and structures on this scale.
In general, nanotechnology is a technology that uses a single building block at the nanoscale, but it can be used more widely. Each ensemble of nanoscale objects has unique, size-dependent properties, so while it is easy to call them nanotechnology, it is better to call them nanomaterial technologies.
Nanotechnology is the production of functional materials and structures on the nanoscale using various physical and chemical methods . Work at the nanometer level offers a number of opportunities to develop novel products and products with attributes and properties that include certain manipulations and measurements at 100 nm (0.1 microns) that fall under the umbrella of nanotechnology. Novel products include medications coated with drug-targeting drug-delivery paints and nanoparticles, foods that taste and burst in food packaging, customized polymers that prevent contamination and decay, clothing that stays clean with textile nanofibers and new materials for automotive and aerospace applications with lightweight, robust and heat-resistant nanocomposites.
The technology is the development of atomic, molecular and macromolecular planes in the longitude range of 1-100 nm . Today, with the revolutionary developments, nanotechnology has become an energetic discipline of science and technology. Creation and use of structures, devices and systems with novel properties and functions in their small to medium sizes .
Nanotechnology is defined as science and technology involved in the design, synthesis, characterization and application of materials and devices with small functional organization in one dimension (one billionth of a meter) in one dimension, nanometer scale (one billionth of a meter ). On this scale, it is important to consider the interaction of individual molecules with groups of molecules in relation to mass macroscopic properties of the material or device, because it controls the basic molecular structure and allows the macroscopy of chemical and physical properties.
Nanotechnology, nanomaterials, nanoscale and other related terms are used in connection with engineering or deliberate manipulation of materials of a dimension or size from 1 nanometer (nm) to 100 nm or the manufacture or selection of them. Various published definitions reference other factors such as function, shape, charge ratio, surface area, volume or other physical and chemical properties. For example, the programme of the National Nanotechnology Initiative defines the understanding and control of matter from 1 to 100 nanometres as a unique phenomenon enabling novel applications (see also:
The Food and Drug Administration (FDA) has not defined its own definition of nanotechnology, but nanomaterials, nanoscale and other related terms with the meaning of being used with a dimension or size from 1 nanometer (nm) to 100 nm have been adopted with regard to technical materials. The European Commission offers a definition of “nanotechnology” which repeats the facts mentioned in the previous definition, that “materials in nanoscale have novel properties that position nanonanos for their potential in the economic market. The definition of the Foresight Institute also mentions the various scientific fields that come into play in nanotechnology.
Based on our current scientific and technical understanding of nanomaterials and their properties, the FDA believes that assessing the safety, efficacy, public health impacts and regulatory status of nanotechnology products should take into consideration the unique properties, behaviors and applications that nanotechnology conveys. According to the first definition, three fundamental dimensions identified as a presence of nanomaterials are size, particle size distribution (PSD) and surface area (Recommendations commissioned, 2011; Bleeker and al., 2013; Boverhof and al., 2015 ). Based on this understanding, the FDA advises on the evaluation and safety and efficacy as well as the effects of nanotechnologies and devices on public health that are considered unique in their properties, behavior and application (Guidance to Industry, Food and Drug Administration, FDA, 2014).
Molecular nanotechnology, also known as molecular manufacturing, describes technical nanosystems and machines on the nanoscale that work at the molecular level. It is associated with molecular assemblers, machines that produce the desired structure of an instrument atom according to the principles of mechanosynthesis. Manufacturing in the context of productive nanotubes is not directly related to, but differs from, conventional technologies for producing nanomaterials such as carbon nanotubes and nanoparticles.
Nanoscience or nanotechnology is the study and application of small things that can be used in other scientific fields such as chemistry, biology, physics, materials science and engineering. Nanotechnology is a science, technology and technology carried out at the nanoscale (1 / 100 of a nanometer). Nanosciences have existed for 150 years since the size of atoms was first determined.
He argued that nanotechnology consists of the processing, separation, consolidation and deformation of materials from one atom to one molecule. About 15 years later he presented the concept of manipulating matter at the atomic level in a lecture entitled “Plenty of room at the bottom,” and the Japanese scientist Norio Taniguchi was the first to describe nanoscale semiconductor processes using nanotechnology. As far as we know, he is the first to use the word nanotechnology, but readers are welcome to correct me.
