DNA存储技术国际发展态势分析

Analysis on the Development Strategies and Trends ofDNA Storage Technology

随着互联网和人工智能等信息技术和数字技术的快速发展,信息量呈指数级飞快增长,传统的硅基存储设备将面临发展瓶颈,而DNA存储具有数据存储密度大、稳定性好、能效低、存储时间长、易备份等优势,可成为数据存储的有效工具。本文对DNA存储技术的发展历程及发展现状进行了概述,对在DNA存储技术领域方面有政策规划与举措的主要国家和地区进行梳理,同时围绕DNA存储技术领域采用文献计量开展国际研发态势研究,结果显示DNA存储技术相关论文发表和专利申请持续增加;国家及地区方面,美国、欧洲及我国已经引起重视并进行了相应布局,美国在DNA存储技术的论文和专利研发上占绝对优势,我国在该领域活跃程度也相对较强。此外,本文进一步分析了该技术领域的发展现状和存在的问题与挑战,并对我国相关技术发展提出了对策建议。

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 re-search 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 technolo-gy,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.
