The smaller you want, the more difficult it is to build. That is, many batteries and optical technology are going back, but a new technique developed by MIT would make it easier for nano-scale materials to be created. It uses a type of absorbent structure to create 3D structures that are 1,000 times smaller than the original.

So far, the 3D techniques for generating small structures were unlikely to be slow and complex. Most 2D nanostructures record on the surface and add continuous layers to get the desired 3D shape. Basically 3D printing is very slow. Some methods exist to accelerate small-scale 3D printing, but they do not know about a number of specialized polymers that work in many applications. The MIT technology is the only one, because they should do almost anything, including metals, polymers and DNA.

Technology is called an image technique; it is called an expansion microscope; It's just running the reverse. In the expansion of the microscope, the tissues are inserted into the hydrogel, and then expanded to make high-resolution searches. The group created large-scale objects in expanded hydrogels, and then shrinked at the nanoscale. They say "manufacturing implosion".

The process begins with a whiteboard using an absorbent material called polyacrylate. A fluorescein molecule solution can infiltrate polyacrylate. Signs watched by sunlight (see below) work. This allows researchers to add molecules at any time. Molecules can be like gold nanoparticles or quantum stitches.

Everything is still "great" at this point – instead of the nanometer of millimeter scale. As far as construction is concerned, researchers add acids to solutions. It eliminates negative calcium in the polyacrylate in the room for hire. It drags them together with these molecules, reducing the length of each dimension by 10 times the total volume of 1,000 times the drop.

With today's laboratory techniques, the team can take a cubic millimeter volume with a 50-nanometer resolution. For larger objects around 1 cubic centimeter, a resolution of 500 nanometers can be obtained. This limitation could be achieved by additional fixing. The team seeks to use this technique to create a lens optic and nano-scale robot improvement.
