Biocomputer can retrieve images from DNA storage

Practical bio computers took a step closer to reality thanks to work by Sivan Shoshani1, Dr. Ron Piran1, Prof. Yoav Arava2& Prof. Ehud Keinan. They have managed to create a Biomolecular computer that is capable of decoding images stored in DNA. Biocomputers are something that I find really interesting and I try to keep an eye out for any new developments in the field. Even though this doesn’t sound like a big deal, its a huge step forward because till now we could only store a very limited amount of data in Biocomputers (stuff like a couple of 0’s & 1’s) but now that we can store an image we are closer to being able to store more complex data and the best part is that since this doesn’t require an interface it can work directly with organic flesh.

A biomolecular computer made in a test tube has proved capable of decoding images stored in DNA. The computer, built by scientists from The Scripps Research Institute and Technion–Israel Institute of Technology have created a mixture of DNA molecules, enzymes, and ATP (the substance that provides energy for our own cells) that successfully decrypts information from a DNA chip, in this case the images shown above. The images were first encrypted onto the chip, and then decrypted by the computer and stained in a way that displays only particular sequences. This means that several images can be overlapped on the same chip, then recovered separately by looking for separate genetic sequences.

The boffins have published their paper in Angewandte Chemie, a German journal of chemistry. Tried to read the paper but unfortunately its behind a pay wall and I am curious about the issue but not curious enough to pay for access.

Thanks to The Verge for the initial story.
