real life \'shrink ray\' can reduce 3d structures to one thousandth of their original size - and could be used to make the next generation of miniature robots  -  absorbent material
Researchers at the Massachusetts Institute of Technology have created a "contraction Ray" in real life that can reduce the 3D structure to one in ten of its original size.
Scientists can put a variety of useful materials into the polymer before the polymer shrinks, including metals, quantum dots, and DNA. The process -
Known as explosive manufacturing
In essence, contrary to the expansion microscope, the expansion microscope is widely used by scientists to create 3D visualization of microscopic cells.
Instead of making things bigger, scientists attach special molecules that stop negative electricity between molecules so they don't reject them anymore and shrink them.
Experts say making this tiny structure is useful in many areas, including medicine and robotics.
This is a way to put almost any material into 3-
Edward Boden, associate professor of bioengineering, Brain and Cognitive Science at the Massachusetts Institute of Technology, said the D-model has Nano-precision.
According to the paper published in the journal Science, using new technologies, researchers can create whatever shape and structure they want.
This method can produce many different shapes, including tiny hollow spheres to microscopic chains.
After connecting useful materials to the polymer "scaffold", they shrink it and produce a structure that is one in ten parts of the original volume.
The researchers used this method to narrow down the hollow link cube and Alice in Wonderland etching.
Scientists say the technology uses equipment already owned by many biological and material science laboratories, making it widely available to researchers who want to try the technology.
At present, scientists can print objects in 3D nano-scale directly.
However, it is only possible for special materials with limited applications such as polymers and plastics to do so.
To overcome this problem, the researchers decided to adopt a technology developed a few years ago.
Resolution imaging of brain tissue.
This technique, known as the expansion microscope, involves embedding the tissue into the gel and then expanding it.
Hundreds of biological and medical research groups are now using an expansion microscope as it enables 3D visualization of cells and tissues with common hardware.
This new technology involves changing processes.
By doing so, scientists can create
Scale the object embedded in the expansion gel and then shrink to the nano scale.
They call it "explosive manufacturing ".
As they did in the expansion microscope, the researchers used a very absorbent material made of acrylic acid.
This is a common plastic in diapers.
Polypropylene ester forms scaffolding that can attach other materials.
It is then bathed in a solution containing sodium fluorescent molecules, which are attached to the scaffold when they are activated by a laser.
Then they used two
The photon microscope observes the target point inside the structure.
They attach fluorescent molecules to these specific locations within the gel.
These act as anchors and bind to other types of molecules in the structure.
Dr. Boyden said that you can fix the anchor where you want it with the light, and then you can fix anything you want on the anchor.
It could be a quantum dot, a piece of DNA, or a gold nanoparticles.
Once the required molecules are attached to the correct position, the researchers contract the entire structure by adding acid.
The acid blocks the negative electricity in the acrylic gel, making them no longer mutually exclusive, causing the gel to shrink.
Using this technology, researchers can reduce objects by 10-
Fold in each dimension (
Overall 1,000-
Volume reduction multiple).
This shrinkage capability can not only improve resolution, but also assemble materials at low resolution
Density scaffold.
This means that it can be easily modified and it becomes a dense solid when the material shrinks.
The researchers believe that these nano-objects can be used to make better lenses for mobile phone cameras, microscopes, or endoscopes.
In the future, the method can be used to make nano-electronic products or robots, the researchers said.
