Scientists at Northwestern University, Illinois’ Center for Synthetic Biology have managed to produce a so-called proof of principle demonstration on DNA storage encoding three bits of information in one hour.

Although this is only a small fraction of what others have achieved (up to 200MB per day), Dr Keith EJ Tayo, an associate professor of chemical and biological engineering, and his team believe there is potential for further progress. There is a huge possibility as -scale parallelization is a real possibility.

According to a report in technology networkWhat Tayo and his colleagues at Northwestern did is a new in vitro Method “to record information to DNA that relies on an enzymatic system”. Key to the process is a non-replicating DNA polymerase called terminal deoxynucleotidyl transferase.

A watershed week for DNA storage


Similar to a data capture approach recently proposed by a Chinese team led by Professor Liu Hong, Dr. Tayo’s approach aims to simplify the current method of chemically synthesizing DNA. The process “does not require washing steps and instead all reagents for DNA synthesis remain in the mixture and the properties of the DNA polymerase are reversibly modified.”

In layman’s terms, writing of data to DNA is fast and simple because it eliminates a few steps whereas reversible modularity may indicate the ability to edit material already committed to DNA.

The process of recording time-sensitive untemplated using local environmental cues, or TDT for turtles, is published in Journal of the American Chemical Society,

Northwestern University news this week was the fourth announcement on DNA storage and with SHANNON, the first commercially available DNA storage device, which is already underway, 2022 could prove to be a very interesting year for a post-silicon data storage world. check out Microsoft’s DNA Storage Announcement and that Georgia Tech Research Institute (GTRI),
