Synthetic DNA is becoming an attractive substrate for digital data storage due to its density, durability, and relevance in biological research. A major challenge in making DNA data storage a reality is that reading DNA back into data using sequencing by synthesis remains a laborious, slow and expensive process. Here, we demonstrate successful decoding of 1.67 megabytes of information stored in short fragments of synthetic DNA using a portable nanopore sequencing platform. We design and validate an assembly strategy for DNA storage that drastically increases the throughput of nanopore sequencing. Importantly, this assembly strategy is generalizable to any application that requires nanopore sequencing of small DNA amplicons.
由于其密度、耐用性以及在生物研究中的相关性,合成 DNA 正成为数字数据存储的一个有吸引力的基质。使 DNA 数据存储成为现实的一个主要挑战是,使用合成测序法将 DNA 重新读取为数据仍然是一个繁琐、缓慢且昂贵的过程。在这里,我们使用便携式纳米孔测序平台成功解码了存储在短合成 DNA 片段中的 167 万字节的信息。我们设计并验证了一种用于 DNA 存储的组装策略,该策略极大地提高了纳米孔测序的通量。重要的是,这种组装策略可推广到任何需要对小 DNA 扩增子进行纳米孔测序的应用。
