Nanotechnology Nanotechnology, also known as nanoparticle technology, is the technology that studies the ability to manipulate matter on the atomic scale, which aims to devise new nanometer techniques and instruments, which are part of a thousand micrometers, This technique does not specialize in the field of biology only, but extends to the properties of materials, which deal with any phenomena at the level of nanostructures, which can lead to new phenomena of electromagnetic and optical material previously unknown. Nanotechnology or Nanotechnology is one of the fields of material science that directly relates to physics, mechanical engineering, bioengineering, and chemical engineering, where it is a collection of disciplines and disciplines that examine the properties of materials at the micro level. This technique can be defined as a scientific application concerned with the production of objects by assembling them at the micro level using their basic components of atom and particles. As all materials consist of a group of atoms that are related to each other according to a given structure, From the atom of another element, which enables scientists to make something new, and here may produce new materials with new characteristics not previously known, which opens many areas in front of humans to discover materials that contribute to the development and service of humanity, as happened when the discovery of the transistor. Difficulties facing nanotechnology The difficulty of this technique in the control of scientists on the atoms, after the fragmentation of the material into a group of atoms and particles constituents, which requires the use of very precise devices in terms of size and measurements and the ability to see atoms and molecules during the examination, Scientists may find it difficult to reach a precise measurement in order to reach the level of maize, and this technology is facing some difficulties because of a lot of fear and controversy about them, fearing their impact on the future. Industries that have started using nanotechnology have entered this technology in the manufacture of a range of goods, especially those that use nanoparticles of various types of oxide, such as: aluminum, titanium, and therefore have become in cosmetics, anti-radiation ointments, as nanoparticles obscure ultraviolet UV is all and the ointment remains transparent. In addition, it is used in the manufacture of anti-stain clothing, and has been added to antibiotics.
