Note: The concept of nano -assemblies is summarized in all the information and code necessary to produce an entity similar to itself. We have a very small machine that knows how to produce its own counterpart , which in nanoscience is referred to as a "nano-assembler".
It is very difficult to create large nanostructures on curved or non-planar surfaces using existing patterning methods. In addition, a variety of current nanopatterning technologies, such as electron beam lithography, optical lithography, interference lithography (IL), etc., cannot cope with all the practical demands of industrial applications in terms of high resolution, high throughput, low cost, large area and patterns on non-planar and curved surfaces. Therefore, new high-volume nanofabrication technology is in urgent need of exploitation and development to meet the extraordinary needs of growing markets. Nanoelectronic lithography is currently considered as a promising nanopatterning method with low cost, high throughput and high resolution, especially for the production of large-scale micro/nanoscale patterns and complex three-dimensional structures, as well as high aspect ratio features . Due to these outstanding advantages, the transformation of optical structures in combination with large-area fabrication becomes a more effective method in this field. In particular, nanoelectronic lithography has great potential to set new standards for the fabrication of miniature, low-cost, and lightweight optics that can be used in many application areas.

The structure of nano-assemblers is one of the properties of nanoparticles, the high surface area to volume ratio of these materials. Using this property, powerful catalysts can be produced in nanometer sizes. These nano-catalysts greatly increase the efficiency of chemical reactions and also significantly prevent the production of waste products in reactions. The use of nanoparticles in the production of other materials can increase their strength or reduce their weight. It increases their chemical and thermal resistance and changes their reaction to light and other radiation. By using nanoparticles, the strength-to-weight ratio of composite materials will increase greatly. Nano-assemblers are made of nanoparticles, and the first effect of reducing particle size is to increase the surface area. Increasing the surface area to volume ratio of nanoparticles causes the atoms located on the surface to have a much greater effect on the physical properties of the particles than the atoms within the particle volume. This property greatly increases the reactivity of nanoparticles. The structure of nano-assemblers is one of the properties of nanoparticles, the high surface area to volume ratio of these materials. Using this property, powerful catalysts can be produced at the nanometer scale. These nanocatalysts will greatly increase the efficiency of chemical reactions and will also significantly prevent the production of waste materials in the reactions.

Conclusion :
The concept of nano - assemblies is summarized in all the information and code necessary to produce an entity similar to itself. We have a very small machine that knows how to produce its own counterpart, which in nanoscience is referred to as a "nano-assembler".
