Nanotechnology: what is it?
Nanotechnologies are methods of working on substancesat the level of their individual atoms. These technologies specialize in manipulations with individual atoms of matter. Objects of nanotechnology are objects with the sizes of the specified range, for example, nanoparticles and nanopowders, i.e. objects whose sizes are in the range up to 100 nm. It can also be nanotubes and nanofibers, nanofilms. This is an incomplete description of what nanotechnology is. it is a complex science.
Application of nanotechnology
Nanotechnologies are divided into three areas: the creation of nanomachines - robots and mechanisms the size of one molecule, the manufacture of electronic circuits, with elements of several atoms in size, and directly, the manipulation of molecules and atoms, as well as the assembly of objects from them. The most common areas of application of nanotechnology:
- If the ability to work on the smallest particles -the main advantage of nanotechnology, is that this can give the development of society's life? The main area of application of such technologies to date is medicine.
- Nanoparticles scientists were able to without damagesurrounding healthy tissues to irradiate a cancerous tumor. Many laboratories are working on the production of accurate and rapid methods of diagnostics with the help of nano - laboratories, nano - chips, etc.
- Scientists conduct tests with drugs in which nanoparticles will be delivered to the diseased organ without touching the healthy ones. Also, work is under way to restore damaged and damaged tissues.
- Nanotechnology will also be used inultramodern medical tomography, where molecular markers are used based on luminous nanoparticles. Among other things, nanotechnology is introduced into the technique of implantation without rejection, mass vaccinations, treatment of diabetes, cancer, arthrosis, etc.
Development of nanotechnologies
The main task of the nanoindustry today iscontrolled mechanosynthesis is the compilation of molecules from atoms by means of mechanical attraction before the onset of action of the appropriate chemical bonds. For mechanosynthesis, you need a special computer - a nanomanipulator that can capture individual molecules and atoms for manipulation within a radius of up to 100 nm. Thanks to the system of interaction between a nanocomputer and a nanomanipulator, it will be possible to organize assembly automated complexes capable of collecting any macroscopic objects and objects according to a previously developed or removed three-dimensional pattern of the arrangement of atoms.
Thanks to such a system, there will be an opportunitythe automatic construction of orbital systems and stations, for example, the colonies on Mars and the Moon, the development of planets by special robotic amoebae, and the launching of a process of underwater construction in the world's oceans and in the air. The possibility of self-building through nanotechnology will lead to addressing global issues, such as the problem of food shortages, energy and housing. Thanks to nanotechnology, the process of designing mechanisms and machines will change - most parts will be simplified due to new ways of assembling. That will allow to design mechanisms and machines that are inaccessible to man. Such mechanisms, in fact, will consist of one detail of high complexity.
Now you know what nanotechnology is, how they develop and what is used by humanity. We wish you good luck!
