Nanotechnology

                                          The utilization of matter on an atomic, molecular, and supra molecular scale for industrial purposes is known as nanotechnology, usually abbreviated as nanotech. The first widely accepted definition of nanotechnology refers to the specific technological objective of accurately manipulating atoms and molecules for the creation of macro scale goods, which is today known as molecular nanotechnology. [1][2] The National Nanotechnology Initiative later adopted a more broad definition of nanotechnology, defining it as the manipulation of matter with at least one dimension scaled from 1 to 100 nanometers (nm). Because quantum mechanical effects are important at this quantum-realm scale, the definition has shifted from a specific technological goal to a research category that includes all types of research and technologies that deal with the special properties of matter that occur below the given size threshold. As a result, the plural term "nanotechnologies" as well as "nanoscale technologies" are frequently used to refer to the vast spectrum of research and applications that share the property of size.

                                      Surface science, organic chemistry, molecular biology, semiconductor physics, energy storage, [3][4] engineering, [5] microfabrication, [6] and molecular engineering are all examples of nanotechnology as defined by size. The accompanying research and applications are similarly broad, ranging from extensions of traditional device physics to whole new techniques based on molecular self-assembly, [8] from producing new materials with nanoscale dimensions to direct control of matter on the atomic scale. Many technologies that developed from traditional solid-state silicon processes for constructing microprocessors are now capable of producing features smaller than 100 nm, classifying them as nanotechnology. Nanotechnology's future ramifications are now being debated among scientists.

                                          Nanotechnology has the potential to generate many novel materials and devices with several uses, including nanomedicine, optoelectronics, biomaterials, energy generation, and consumer items. Nanotechnology, on the other hand, generates many of the same problems as any new technology, including concerns about the toxicity and environmental impact of nanomaterials[9], as well as their possible consequences on world economies and speculation about different apocalyptic scenarios. These issues have sparked a discussion among advocacy organizations and governments over whether nanotechnology requires specific regulation.

Nanomaterials

           The area of nanomaterials encompasses subfields that generate or research materials with special features due to their nanoscale size. [40]

Many materials that may be beneficial in nanotechnology have been developed as a result of interface and colloid research, including carbon nanotubes and other fullerenes, as well as different nanoparticles and nanobots. Fast ion transport nanomaterials are relevant to nanobiotic and optoelectronics.

Nanoscale materials can also be employed in bulk applications; the majority of current commercial nanotechnology uses are of this kind.

The use of these materials for medicinal purposes has advanced; see Nanomedicine.

Nanoscale materials, such as cyanobacteria, are occasionally employed in solar cells to reduce the cost of typical silicon solar cells.

Application development using semiconductor nanoparticles for use in next-generation goods such as display technologies, lighting, solar cells, and biological imaging; see quantum dots.

Nanomaterials have recently been used in a variety of biological applications, including tissue engineering, medication transport, antibacterials, and biosensors.
