DNA computing, currently a hot research field in information processing, has the advantages of parallelism, low energy consumption, and high storability, therefore, it has been applied to a variety of complicated computational problems. The emerging field of DNA nanotechnology has also developed quickly; within it, the method of DNA strand displacement has drawn great attention because it is self-induced, sensitive, accurate, and operationally simple. This article summarizes five aspects of the recent developments of DNA-strand displacement in DNA computing:(1) cascading circuits;(2) catalyzed reaction;(3) logic computation;(4) DNA computing on surfaces; and(5) logic computing based on nanoparticles guided by strand displacement. The applications and mechanisms of strand displacement in DNA computing are discussed and possible future developments are presented.

7岁的女儿有一天用几张白纸和订书钉做了一个本。她欣赏着自己的本,高兴地说:“妈妈,我真高兴,真有成就感!”我接过本,见封皮上写着“日记本”几个字,翻开内页,是用红线条画的不太工整的格子。于是,我就见到了下面的文字:  “妈妈给了我生命。”看到女儿这样开头,我很兴奋,颇有点意味。接着她又写道:  “可我不给我后代生命。”见此,我的心不禁一提,脑子里立刻产生了一个大问号,为什么呢?  只见她又写道:“
