Researchers at Peking University have introduced a transformative approach to DNA data storage, termed “epi-bits,” which utilizes enzymatic methylation for efficient, high-density data encoding. This innovative method enhances the practicality of DNA as a storage medium, making it both scalable and cost-effective. In their study published in Nature, led by Cheng Zhang and Long Qian, the team demonstrated how epigenetic modifications could be added to universal DNA templates to encode data in a parallel and programmable manner.
DNA offers remarkable storage density, with one gram capable of holding 215,000 terabytes, making it ideal for managing the growing challenges in digital information. Traditional DNA storage methods are slow and costly due to sequential nucleotide synthesis; however, the epi-bit method improves efficiency significantly. It allows users, including volunteers from diverse academic backgrounds, to personalize their DNA storage via a platform called iDNAdrive, achieving a low error rate in data retrieval.
In practical applications, the researchers successfully encoded 275,000 bits of data, showcasing its potential for efficient, accessible, and versatile data storage solutions. The findings highlight the significance of the epi-bits technology in the evolving landscape of digital data management.
