Nanotechnology is the study of manipulating matter on an atomic and molecular scale. Generally, nanotechnology deals with developing materials, devices, or other structures with at least one dimension sized from 1 to 100 nanometres. Nanotechnology entails the application of fields of science as diverse as surface science, organic chemistry, molecular biology, semiconductor physics, microfabrication, etc.

Nanoscience is the study of atoms, molecules, and objects whose size is on the nanometer scale. Atoms are a few tenths of a manometer in diameter and molecules are typically a few nanometres in size. Nano Science is a technology directed at the Nano scale. It is the uses and study related to very small things that can be used in all the other fields of science like biology, physics, chemistry, engineering and Materials sciences.

Nanostructures are structures that range between 1 nm (molecular scale) and 100 nm in at least one dimension. Most are synthetic and can be engineered to wide range of physical properties. Nano surfaces, cylindrical nanotubes, and Nano spheres are common nanostructures.

Nano electronics holds few answers for how we might increase the capabilities of electronics devices when we reduce their weight and power consumption. Nano electronics and technology are widely used in all aspects of modern life. Life Safety, Healthcare, Transportation, Computing, Energy and Telecommunications are some of the major fields benefiting from the growth of Nano electronic applications.

Materials science and engineering, is a discipline which deals with the discovery and design of new substances. The research in material technological know-how includes in Transmission electron microscopy in cutting-edge substances technological know-how, advancements of materials technological know-how, Mining and metallurgy, power substances there are 50 universities and a marketplace to growth of 5.1% over the duration 2014-2019. The strength materials marketplace changed into predicted to be $7,292.eight million in 2014 and is projected to boom of 7.8% from 2014 to 2019. Mining and metallurgy for a market share of 68.3% in 2014 and is predicted to growth of 8.3% through 2019. 18 new research tasks can be implemented via quit of 2016.

Nanomaterials describe, in principle, materials of which a single unit is sized (in at least one dimension) between 1 and 1000 nanometres (10?9 meter) but is usually 1—100 nm (the usual definition of nanoscale). Nanomaterials are slowly becoming commercialized and beginning to emerge as commodities.

Nanochemistry is a new discipline concerned with the unique properties associated with assemblies of atoms or molecules on a scale between that of the individual building blocks and the bulk material. Nanochemistry is the use of synthetic chemistry to make nanoscale building blocks of desired shape, size, composition and surface structure, charge and functionality with an optional target to control self-assembly of these building blocks at various scale-lengths.

Nanophotonics or Nano-optics is the study of the behavior of light on the nanometre scale. It is considered as a branch of optical engineering which deals with optics, or the interaction of light with particles or substances, at deeply subwavelength length scales.

Nanotechnology is the science which deals with the processes that occur at molecular level and of nanolength scale size. The major studies in the nanotechnology include nanosized particles, their function and behaviour with respect to other systems. The tremendous capabilities of nanoparticles have changed the perspective and scope of nanotechnology towards development into an adjuvant field for the remaining fields of life sciences. Nanotechnology is the ability to understand and control materials at the very smallest scales, from around 100 nm to the dimensions of single atoms; At this Nano scale the properties of these nanosized particles are vary from the conventional medicines.

Graphene is an allotrope of carbon in the form of a two-dimensional, atomic-scale, hexagonal lattices in which one atom form each vertex. It is the basic structural element of other allotropes, including graphite, charcoal, carbon nanotubes and fullerenes. It can be considered as an indefinitely large aromatic molecule, the ultimate case of the family of flat polycyclic aromatic hydrocarbons.

Tissue engineering is the usage of a group of cells, engineering and materials means and proper biochemical and physicochemical factors to rise or replace biological tissues. Tissue engineering includes the usage of a scaffold for the making of innovative feasible tissue for a medical purpose. While it was once categorized as a sub-field of biomaterials, having settled in scope, importance and it can be considered as a field in its own.

Materials chemistry involves the use of chemistry for the design and synthesis of materials with interesting or potentially useful physical characteristics, such as magnetic, optical, structural or catalytic properties.

Optics and Lasers in Engineering aims to provide an international forum for the interchange of information on the development and application of optical techniques and laser technology in engineering. Emphasis is placed on contributions dealing with the practical use of methods and devices, the evaluation of results and developments and enhancement of solutions and new theoretical foundations for experimental methods.

Nano devices are critical enablers that will allow mankind to exploit the ultimate technological capabilities of electronic, magnetic, mechanical, and biological systems. Nano sensors are chemical or mechanical sensors that can be used to detect the presence of chemical species and nanoparticles, or monitor physical parameters such as temperature, on the nanoscale.
