Folding DNA, which is called DNA origami is not a new thing, but doing it by automation is certainly a new process. Researchers from Karolinska Institute in Sweden have created a new automated method to fold the DNA and built a rabbit shaped bunny to prove it. The researcher’s team just not wanted to make bunny shape structure by folding the DNA, but they wanted to develop a fully automated 3D printing like method to fold the building blocks of life.



This filed is called DNA nanotechnologies, which deals with the design and manufacture the structures of DNA. This DNA folding method can also be used to develop structures, which will help in delivering drugs to human body more precisely. Earlier this method was expensive in both ways in time and money, but this new method created by researchers from Sweden promises to be cheaper and simpler.

The researchers have designed software, which will draw 3D complex shapes like shapes of a boll, a bottle or bunny by using a collection of polygon to form the mesh. After this they have used their developed computer algorithm to organize the DNA strands along the edges of the mesh to finally from the desired 3D object.

According to a report from The Verge, when researchers want to form a bunny shaped objects by folding the DNA. The computer will list out the short DNA sequences, which can automatically assemble to form the bunny structure at right temperature. Then the company has sent their computer generated list to a company named Integrated DNA Technologies, which deals in manufacturing DNA from viruses. The company has sent them a tube filled with almost 200 short DNA strands. When they, put these strands of DNA through cooling and warming procedures as indicated by algorithm of the computer, they got the exact bunny shaped structure. This can also be used to deliver drugs at the right part of the body and can be used deliver cancer drugs and help the scientists to know the communication process of the cells in the body.
