中文摘要：

DNA不只是遗传物质,还能通过折叠形成特定的二维、三维结构,作为一种天然纳米材料可参与各种功能结构和纳米器件的构造。DNA纳米技术从被提出到现在的三十多年间,得到了飞速发展,被应用于众多领域,对纳米科学产生了重大影响。本文将主要从三种典型的DNA纳米结构和DNA纳米技术的应用两个方面进行综述,并对DNA纳米技术的前景进行展望。

英文摘要：

In addition to its genetic function,DNA is one of the most promising nanomaterials by selfassembling into predictable 2Dor 3Dnanostructures.Since DNA nanotechnology was proposed in 1982,DNA molecules have been used to build a variety of functional structures and nanodevices for more than30 years and found wide applications in fields such as detection,cancer therapy,nanomachine,computer science and so on.In this review,we will recount three typical DNA nanostructures,outline some applications in detection and cancer therapy,and give a future perspective of DNA nanotechnology.
