中國的科學家們發明了一種口罩，可以檢測空氣中常見的呼吸道病毒，包括流感和冠狀病毒，并在10分鐘內通過移動設備向佩戴者發出警報。

A group of Chinese scientists have developed a face mask that can detect viral exposure.

中國的科學家團隊研發出一款口罩，可以檢測空氣中的呼吸道病毒。

Respiratory pathogens that cause COVID-19 and influenza spread through small droplets and aerosols released by infected people when they talk, cough, and sneeze.

誘發新冠肺炎和流感的呼吸道病原體，可通過受感染者說話、咳嗽和打噴嚏時釋放的小飛沫和氣溶膠傳播。

The wearable bioelectronic mask designed by the researchers from Tongji University can detect common respiratory viruses, including influenza and the coronavirus, in the air in droplets or aerosols, and then alert the wearers via their mobile devices.

這款可穿戴生物電子口罩由同濟大學的研究人員設計，可以檢測空氣中飛沫或氣溶膠中含有的常見呼吸道病毒，包括流感病毒和冠狀病毒，然后通過移動設備提醒佩戴者。

The highly sensitive face mask is capable of measuring trace-level liquid samples of 0.3 microliters and gaseous samples at an ultra-low concentration of 0.1 femtograms per milliliter, according to the study published this week in the journal, Matter.

根據本周發表在期刊《Matter》上的一項研究，這款高靈敏度的口罩能對0.3微升的含有病毒蛋白質的液體做出反應，該口罩還能檢出超低濃度（0.1fg/ml，即1ml空氣中的1000萬億分之一克）的氣體介質樣本。

The detection benchmark for liquid containing viral proteins in an enclosed chamber is "about 70 to 560 times less than the volume of liquid produced in one sneeze and much less than the volume produced by coughing or talking," said the paper's corresponding author Fang Yin, a professor at Tongji.

該論文通訊作者、上海同濟大學教授方寅說，封閉室內對含有病毒蛋白的微量液體的檢測基準“是一個噴嚏產生液滴的約1/70至1/560，比咳嗽或說話產生的液滴小得多。”

Fang's team designed a small sensor carrying three types of synthetic molecules that can simultaneously recognize surface proteins on SARS-CoV-2, H5N1, and H1N1.

該團隊設計了一個攜帶三種合成分子的小型傳感器，可以同時識別新冠病毒、甲型H5N1流感病毒和甲型H1N1流感病毒的表面蛋白。

Once those molecules click onto the target proteins, an ion-gated transistor integrated into the mask will amplify the signal and alert the wearers, according to the study.

一旦這些分子與目標蛋白結合，口罩中的離子門控晶體管將放大信號，并提醒佩戴者。

The designers said they can easily update the wearable device to detect novel respiratory viruses.

設計者稱，將來如果出現新的呼吸道病毒，可以很容易地更新傳感器設計，以檢測新的病原體。
