According to the form of work, nanotechnology divides into:
Reduction in size. Literally from the top (top) to bottom (bottom). Mechanisms and structures of nanotechnology are miniaturized at the nanoscale.
This type of nanotechnology has been the most frequent to date, more specifically in the field of electronic technology where dominance miniaturization.
Auto assembled. Literally from below (minor) to above (major). It starts with an anthropometry as a molecule and through a process of assembly or auto assembly.
A mechanism is created greater than the mechanism with which we started. This approach, which some consider as the only “true” nanotechnological approach, must allow a matter to be controlled in an extremely precise way. In this way, we can free ourselves from the limitations of miniaturization, very present in the field of electronics.
According to the field in which the nanotechnology is worked, it is divided into:
This technology is based on biological systems that exist in an aqueous environment, including genetic material, membranes, enzymes and other cellular components.
They are also based on living organisms whose forms, functions, and evolution are governed by the interactions of Nano-metric scale structures.
It is the technology that is dedicated to the manufacture of structures in coal, silicon, inorganic materials, metals, and semiconductors.
Dry and Dry Nanotechnology
The latest proposals tend to use a combination of wet type and dry type. A DNA strand is designed to force molecules into very specific areas by allowing covalent bonds to form only in very specific areas.
The resulting shapes can be manipulated to allow positional control and fabrication of nanostructures.
With this branch, one can work in the modeling and simulation of complex structures of manometer scale. You can manipulate atoms using computer-controlled nanomanipulators.
Sometimes also called molecular fabrication, is a term given to the concept of nanotechnology (machines at the nanoscale) operating on a molecular scale.
It is based on the fact that manufactured products are made from atoms. The properties of these products depend on how these disposed of atoms are.
For example, if we relocate the atoms of graphite (composed of carbon) from the pencil mine, we can make diamonds (pure crystallized carbon). If we relocate the atoms of the sand (composed basically of silica) and add some extra elements are made the chips of a computer.
From the countless examples found in biology, he knows that billions of years of evolved nutrition can produce sophisticated and optimized biological machines.
However, other researchers have proposed that advanced nanotechnology, though perhaps initially implemented through mimetic principles, could eventually be based on the principles of mechanical engineering.
