Abstract: With the rapid development of information technology and digital technology, such as the Internet and artificial intelligence (AI), the amount of information is growing exponentially, and the development of traditional silicon-based storage devices will face bottlenecks. DNA storage can become an effective tool for data storage since it has the advantages of high data storage density, good stability, low energy efficiency, long storage time and easy backup. In this paper, the development history and current situation of DNA storage technology are summarized, and the major countries and regions that have policy plans and measures in the field of DNA storage technology are sorted out. Meanwhile, the international research and development situation in the field of DNA storage technology is studied by adopting bibliometric methods. The results show that the number of papers published and patent applications for DNA storage technology continues to increase. In terms of countries and regions, the United States, Europe and China have paid attention to it and made corresponding layouts. The United States has an absolute advantage in research papers and patens development on DNA storage technology, while China is relatively active in this field. In addition, the development status, existing problems and challenges in this field are summarized and prospected, and some countermeasures and suggestions are put forward for the development of related technologies in China.
