Abstract: This article employs the popular expression “engraved in DNA” as an engaging introduction to elucidate the developmental trajectory and potential applications of DNA data storage technology. The discussion begins with the pioneering phase, detailing the encoding, synthesis, storage, and retrieval processes along with the technical limitations of early implementations. Subsequently, it highlights the innovative “Bi Sheng-1” movable-type storage inkjet printer system and the catalytic role of enzymatic synthesis in achieving automated, high-speed data writing. The paper concludes by examining practical applications in archival preservation and space exploration, while addressing accompanying ethical considerations, thereby stimulating reader interest in this frontier of chemical science.

Key words: DNA data storage, Technological evolution, Anthropomorphic narrative, Prospects and challenges
