In science fiction, "burning rays" are the easiest way to make large objects much smaller, but here the realities are not so simple. The creation of so-called "nano-scale" objects is difficult for MIT researchers to make it a bit simpler, so that scientists have the original size to achieve a three-dimensional dimensional structure effectively. .
When creating this new system, Edward Boyden and his students' MIT teachers began a technique that used to do things bigger. It is called the expansion microscope, which is used to increase the size of cells and tissues by embedding biological material, with the growth of polymeric gel.
Developing a 3D object reduction system, researchers used a similar reverse technique. First, a polymer scaffold is formed to add 3D particles to other particles. These particles, which can be anything from metal to biological molecules, adapt themselves to any desired shape and using "light anchors".
"You will put your anchor in the desired location with the light you want, and later you can attach the anchors," explains Boyden. "It can be a quantum point, it could be a part of DNA, it could be a gold nanoparticle."
Once the desired shape has been constructed, an accelerator that causes the contracting of polymers is explained, reducing the object by 1,000 times.
The technique can be highly adaptable and useful in many applications. For now, researchers suggest the use of camera lens production and microscopes or endoscopes. Far beyond that, the team also says that the nano-scale robot could be built. Perhaps, "gray goo" is the apocalypse after mankind?
