DNA nanoconductors have been developed that can be used to create genetic computers

Recently, a growing number of scientists have expressed their opinions about artificial intelligence, and robotics has gone so far in creating humanoid robots that some robots seem (but not yet internally) to be very different from humans. But let's take a look at the question from the other side. What if we consider the structure of the human body from the computer's point of view? After all, not without reason many "computer" terms are borrowed from human organs and systems. Take at least the same neural network. Some scientists also thought about it a long time ago, expressing the idea of ​​creating a "genetic computer". That is, a computer located literally on a DNA chain. And recently work in this area has moved from a dead center.

Experts from the Helmholtz Center of Dresden-Rossendorf are responsible for the development, and the scientists Bez Teshome and Arthur Erbe are heads. Under their leadership, it was possible to create a method for applying a gold coating to nanoconductors made from segments of DNA molecules. Such details can be collected into whole circuits, which can become the basis for creating a "genetic computer". According to Arthur Erbe,

"The main advantage of using DNA is that with its help you can quickly create very complex circuits at the nanoscale level. Production of complex circuits is possible thanks to a technology called DNA origami, which allows you to create complex spatial structures through a controlled and programmable process of self-assembly. "

Controlling the sequence of assembling a DNA molecule is accomplished by adding certain chemical elements to the solution and changing the temperature of the solution, which makes it possible to create 3D objects of extremely complex shape from DNA. From DNA, something like nanotubes gathers, and then nanoparticles of gold are located along the resulting nanotubes. Thus, it is possible to create a nanowire, which is still necessary to be supplied with an electric current. This is already happening under the increase of a high-precision electron microscope. As a result of all the above manipulations, completely working circuits are obtained, from which it is already possible to assemble the nodes of the "genetic computer". As Bezu Teshome says,

"Our gold DNA nanoconductors are capable of carrying a current large enough for their size of power. In the future, we plan to develop DNA nanoconductors with a complex structure that have several branches, with which it will be possible to connect a large number of parts to entire circuits. "
