Thank you so much dear Dr. Yahia Z Hamada for your nice answer and provided link. I appreciate it.

Kind regards

Nanoscience and nanotechnology One of the fields of materials science and communication of these sciences with physics, mechanical engineering, biological engineering and chemical engineering constitute multiple branches and disciplines within this science, all related to the study of the properties of matter at this small level.

The difficulty of nanotechnology lies in the extent to which atoms can be controlled after fragmentation of their constituents. It therefore requires very precise instruments in terms of size, measurements and methods of seeing molecules under examination. The difficulty of achieving accurate measurement when reaching the level of maize is another difficulty facing this emerging new science. In addition, there is still controversy and concerns about the effects of nanotechnology, and the need to control.

Nanotechnology applications are wide-ranging and involve many industrial, military, medical, agricultural, and other fields. For example, a wide range of raw materials are improved to make changes in the physical properties of small or nanoparticles. Nanomolecules, for example, benefit from a significant increase in surface area to volume ratio. And then their optical properties, including the fluorescent function of the particle diameter. When combined into a mass material, nanoparticles strongly affect the mechanical properties of the material, including hardness or softness. For example, conventional polymers can be reinforced by the use of nanoparticles found in new materials that may be used as lightweight substitutes for metals. As a result, the social benefit of nanoparticles can be expected to increase. These nanoparticles will help reduce the weight associated with increased stability and improved function. In addition, practical nanotechnology represents the increasing ability to accurately manipulate material according to previously impossible standards, providing a range of possibilities that others had not previously imagined - so it is not surprising that few areas of human technology have been excluded from the benefits of using And application of nanotechnology.

Nanoscale engineering is closely related to nanotechnology. The first nanotechnology program in the world has been launched at the University of Toronto's Engineering Science Program as one of the options for study in recent years. In 2003, the Lund Institute of Technology began its nanotechnology program. In 2005, Waterloo University created a unique program that provides a full degree in nanotechnology engineering. The University of California at San Diego and shortly thereafter in 2007 with a special department of nanotechnology.

Nanotechnology is the new revolution of science and technology, it'll change everything in life, like establishing an elevator to the moon, transparent cloths, superconductive electronics at the room temperaure.....

It is manipulating material at the nano meter scale, huge budgets around the world are being dedicated for research in nanotechnology.

If 30 nm scale is considered as nanotechnology, we can say that nano is moving now from research to factory, if 3 nm is targeted as nanotechnology, it is expected around 2060, life will be unbelievable then.

As is geo-technical engineering, I expect that it'll be demonstrated in sensors.

A very interesting research medium - amongst enormous counts of journals, conferences, books - is the Nanonature journal, very interesting.

One definition is "the manipulation of matter with at least one dimension sized from 1 to 100 nanometers."

Personally, I find this hard-coded size limits very subjective. Who decided? One example of nanotechnology is colloid science and the valid size range goes far beyond 100nm.

Honestly, much of "nano" is old science in new clothes.
