日本研发出新型口罩 遇新冠病毒能在紫外线下发光

日本的科学家近日研发出了一种新型口罩，如果佩戴者感染了新冠病毒，这种口罩就能在紫外灯下发出亮光。有了这款口罩，人们在家中就可以自测是否感染了新冠病毒。

A team of Japanese scientists has created a prototype for a mask filter that glows under ultraviolet light and reveals traces of the COVID-19 virus if the wearer is infected.

日本的一个科学家团队日前研发出了一款口罩过滤片样品，如果佩戴者感染了新冠病毒，这款口罩就会在紫外线灯照射下发光，提示病毒的存在。

Scientists from the Kyoto Prefectural University say that the masks they've made contain an additional filter within its layers. When removed and sprayed with a fluorescent dye containing antibodies, the filter will glow when placed under UV light if traces of the COVID-19 virus are detected.

京都府立大学的科学家称，他们制作出的这款口罩内含有一层额外的过滤片。把这层过滤片取出来喷上含有新冠抗体的荧光染料后，如果接触到新冠病毒，这层过滤片就能在紫外灯照射下发光。

According to a press release from the university, the team developed this method by first injecting an inactive form of the COVID-19 virus into female ostriches. From there, they worked to extract antibodies from the eggs of these female ostriches, infusing these antibodies into the fluorescent spray.
