Technology writing binary data

chain synthetic polymer

   Researchers from the Institute Charles Sadron (Institut Charles Sadron) and the University'aix-Marcelle (Aix-Marseille Universite, France, have developed a new technology write binary data to a sequence chain synthetic polymer, the thickness of which is approximately 60 thousand times less than the thickness of a human hair. This technology has a great future in the near future become a repository for digital data, which has not only the small size today, and the biggest indicator of the density of information storage, but also has some other very attractive options. Currently storage is one of zettabyte (1 billion terabytes) requires about a thousand pounds of cobalt alloy, the material used in the plates of modern hard disks. Setbit data stored as a sequence of chains of the DNA molecule, will require only about 10 grams of this material.

Synthesis of DNA sequences

the creation of synthetic DNA

   The synthesis of DNA sequences is very similar to the stringing pearls on a thread. In the simplest case, the information in this approach is encoded in the traditional form of zeros and ones. Each value corresponds to a specific sequence of chemical components called monomers, which, by means of chemical methods are concatenated in a specific order in a circuit. But by using a fairly conventional mass spectrometer, a device that is use for reading the sequence of DNA, written information can be read with a high level of confidence. We have already talked about the fact that George Church George Church, Professor of genetics from the Weiss Institute at Harvard University, using the method of DNA synthesis has created 70 million copies of his books on genetics, which was placed inside a tiny drop of liquid. But French researchers have managed to encode a sequence of bases in the polymer molecule about 10 megabytes of information, and in the future the amount of information can be increased by several orders of magnitude. Besides DNA, and synthetic polymer molecules, under certain conditions, can be kept unchanged at least 100 thousand years, and they are a more reliable method of long-term storage of information than any existing technology, including optical and hard drives.

Polymer Assembly Technology "DNA"

Technology writing binary

   But the biggest obstacle which is not yet practical to use DNA for information storage, is time. For the synthesis of DNA, which were coded above 10 megabytes of information, it took a few days, and decoding (reading) these data are for eight hours. However, given the progress in this direction, you can expect dramatic breakthroughs can occur already in the next two to three years, after which it will be possible to record information on DNA in amounts comparable to that of feature films, which will leave more or less adequate. "Clean DNA is really a biological object, created by nature itself. However, DNA is not in all cases is ideal for use in nanotechnology and other areas. These areas require something completely different" - the researchers wrote, "Our idea is that by using chemical methods, we can synthesize long polymeric molecules with a given structure, and the process of their synthesis can be much cheaper and faster process for synthesis of artificial DNA".
