英国《自然》下属《科学报告》期刊6月5日的一篇论文中,描述了一种方法,可以在敏感类的爆炸物、固态或液态的药品中甚至墨水上做标记,这就是基于纳米粒子独特热性能的隐形条形码。其在安保及防伪领域,尤其是跟踪、验证和追寻各种物品来源等方面,被看做是非常有前途的新方法。条形码人们已很熟悉,这种按照一定的编码规则排列,可以表达一组信息的图形标识符,其实是随计算机与信息技术发展而诞生的,带动了自动识别系统与数据采集技术。但目前广泛用以标记物品的可见条形码,
In a June 5 paper published in the June 5 issue of the journal Nature in the United Kingdom, Nature reported a way to label sensitive explosives, solid or liquid drugs, or even ink, which is based on nanoscale Invisible bar code for unique thermal properties of particles. It is regarded as a very promising new method in the fields of security and anti-counterfeiting, especially in tracking, verifying and searching for the sources of various items. Barcode people are already familiar with this kind of graphic identifier, which is arranged according to certain coding rules and can express a group of information. In fact, it was born with the development of computer and information technology, which led to the automatic identification system and data collection technology. But currently widely used to mark items visible bar code,
