Despite the efficiency of electronic data storage systems, they pale in comparison to DNA, nature’s own data storage system. A groundbreaking technique, akin to a printing press, now allows for the effortless encoding of data onto DNA, democratizing the process for all.
Conventional DNA data writing involves painstakingly synthesizing strands letter by letter, akin to threading a string with beads. With billions of bases in a single DNA sequence, this method is inherently slow and laborious.
However, the innovative DNA printing press has revolutionized the process, utilizing a set of 700 DNA bricks, each containing 24 bases, that function as movable type pieces. This advancement allows for the simultaneous encoding of data at a rate of 350 bits per reaction, a significant leap in efficiency.
Instead of the traditional GCAT letters, data is now encoded in binary code with ones represented by DNA bricks with chemical markers and zeroes by those without. Through meticulous experimentation, images containing thousands of bits were successfully stored and retrieved with exceptional accuracy.
As a user-friendly demonstration, a group of individuals encoded text totaling around 5,000 bits using a software platform and achieved an impressive 98.58% data read-back accuracy. The allure of DNA data storage lies in its remarkable data density, with potentially over 10 billion gigabytes stored in just 1 cm3 of DNA.
With the DNA printing press mimicking the efficiency of movable type printing in ancient times, this method allows for swift data encoding, drawing inspiration from the intricate cellular processes of our bodies. Through the strategic placement of DNA bricks resembling movable type, data is seamlessly written onto DNA strands, revolutionizing the storage process.
By harnessing methyl groups as markers and employing enzymes to copy data onto DNA templates, the potential for massive-scale data writing on DNA is unlocked, ushering in a new era of accessible data storage solutions.
This groundbreaking research has been published in the prestigious journal Nature, marking a significant milestone in the field of DNA data storage.
