日本研發(fā)新冠自測口罩

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.

日本的一個科學(xué)家團隊日前研發(fā)出了一款口罩過濾片樣品，如果佩戴者感染了新冠病毒，這款口罩就會在紫外線燈照射下發(fā)光，提示病毒的存在。

Scientists from Kyoto Prefectural University say that the masks contain an additional filter within its layers.

京都府立大學(xué)的科學(xué)家稱，他們制作出的這款口罩內(nèi)含有一層額外的過濾片。

When removed and sprayed with a fluorescent dye containing antibodies, the filter will glow under UV light if traces of the COVID-19 virus are detected.

把這層過濾片取出來噴上含有新冠抗體的熒光染料后，如果接觸到新冠病毒，這層過濾片就能在紫外燈照射下發(fā)光。

Speaking to Japanese news outlet Kyodo News, researcher Yasuhiro Tsukamoto said that he conducted experiments with 32 people infected with COVID-19 over a 10-day time frame.

研究員冢元安弘告訴日本共同社說，他在10天時間內(nèi)對32名新冠病毒感染者開展了實驗。

The researchers found that the masks worn by these 32 testers glowed brightly and showed traces of the COVID-19 virus after being sprayed with the antibody spray and held under a UV light.

結(jié)果發(fā)現(xiàn)，32名測試者佩戴過的口罩在噴灑過抗體噴霧后能在紫外燈下發(fā)出亮光，表明口罩上有新冠病毒。

Tsukamoto's team also noted that the glow faded over time as the patients recovered and their viral load decreased.

冢元安弘的團隊還指出，隨著患者康復(fù)，病毒載量降低，口罩發(fā)出的光也會減弱。
