病毒检测口罩，这会是个 big deal 吗？

文学城有这则新闻：

据MSN新闻网站5月14日报道，哈佛大学和麻省理工学院的研究人员正在开发一种口罩，当口罩检测到新冠病毒时就会亮起来。

在有效的药物和更困难的疫苗出来之前，这个最有希望改变美国现状，拯救经济。有不同意见，欢迎探讨！

Jim Collins, whose bioengineering lab at MIT began work on the sensors in 2014, said the technology could be rolled out on a wider scale if it proves successful.

He said: "As we open up our transit system, you could envision it being used in airports as we go through security, as we wait to get on a plane.

The team are said to be in the “very early stages” of the project but are hoping to begin trials within the next few weeks.

Collins said once the sensors detect a trace of coronavirus, they will give off a fluorescent signal within one to three hours – considerably less time than the 24 hours it currently takes to run tests for coronavirus.
