New mask to detect coronavirus in just 10 minutes, alert users via app

Scientists have developed a face mask that can detect the coronavirus in just 10 minutes.

The mask is supposedly highly sensitive and is able to identify common respiratory viruses such as Covid-19 and influenza by the droplets or aerosols that are present in the air.


The mask wearers are alerted via an app on their phones.

These virus-containing molecules have a protracted suspension time in the atmosphere, especially the tiny aerosols which are released by infected people when they talk, cough, or sneeze.

"Previous research has shown face mask wearing can reduce the risk of spreading and contracting the disease. So, we wanted to create a mask that can detect the presence of virus in the air and alert the wearer," said Dr Yin Fang, the study's corresponding author and a material scientist at Shanghai Tongji University.

He adds, "Our mask would work really well in spaces with poor ventilation, such as elevators or enclosed rooms, where the risk of getting infected is high.”

The sensor in the mask contains aptamers, a type of synthetic molecule that can identify proteins in pathogens.

Aptamers can recognise particular proteins of pathogens like antibodies, and they were used by the research team to create a tiny sensor.

The team reportedly changed the multi-channel sensor in their proof-of-concept design so that it could simultaneously recognise the surface proteins on the SARS-CoV-2, H5N1, and H1N1 viruses, the Mint informs.

Thus, the mask can also detect swine flu and bird flu.

The mask was tested by researchers in China by spraying liquid containing virus proteins onto the mask in an enclosed chamber.

According to the findings that were published in the journal Matter, the sensor responded to just 0.3 microlitres of the liquid which is reportedly between 70 and 560 times less than the amount of liquid produced by one sneeze, and even less than the amount created by coughing or talking, The Telegraph reports.

Even smaller quantities of viral proteins reportedly obtained a response from the sensor.

The researchers state that once the aptamers bind to the virus proteins in the air, an ion-gated transistor alerts wearers to the pathogens via their phones.

The mask supposedly swiftly detects even minute levels of airborne viruses due to the novel and extremely sensitive device called an ion-gated transistor.

Ion-gated transistor is an effective transistor architecture for enabling integrated, real-time sensing and stimulation of signals from living organisms, Science Advances explains.

Dr Yin Fang affirms, "In the future if a new respiratory virus emerges, we can easily update the sensor's design for detecting the novel pathogens."

He is quoted as saying, "Currently, doctors have been relying heavily on their experiences in diagnosing and treating diseases. But with richer data collected by wearable devices, disease diagnosis and treatment can become more precise.”

The team now wants to develop the mask to detect diseases even faster and create wearable devices that can help people manage other illnesses such as cancer and heart disease.

Court to review teen's sentence in Bhim Kohli case

THE seven-year prison sentence handed to a 15-year-old boy convicted of the manslaughter of 80-year-old Bhim Sen Kohli is to be reviewed under the UK’s Unduly Lenient Sentence (ULS) scheme.

The Attorney General’s Office confirmed on Friday (5) that the teenager’s sentence will now be considered by the Court of Appeal.

Dalai Lama hopes to live 'beyond 130 years'

THE Dalai Lama said on Saturday (5) he hopes to live until he is more than 130 years old, two decades longer than his previous prediction, following his assurance to followers that he would reincarnate as the spiritual head of the faith upon his death.

The Nobel Peace Prize winner was speaking during a ceremony organised by his followers to offer prayers for his long life, ahead of his 90th birthday on Sunday (6), and as China insists it will choose his successor. The Dalai Lama told Reuters in December he might live to 110.

Met Office warns of potential third UK heatwave by mid-July

Key points

  • Met Office forecasts rising temperatures by mid-July
  • Possible third heatwave after record-breaking June
  • High pressure system likely to bring hot air from the Atlantic
  • Yellow rain warning and flood alerts issued in parts of Scotland and Cumbria

Possible heatwave to return by mid-July

The UK could experience its third heatwave in a month by mid-July, the Met Office has said. Forecasters expect rising heat and humidity during the second weekend of July, following two weekends of unusually warm weather in late June.

June was officially the hottest on record in England, and the return of high temperatures could mean another heatwave for parts of the country. However, the Met Office cautioned that it is too early to confirm how hot conditions will get.

Manchester Police probes over 1,000 child sexual abuse suspects

GREATER MANCHESTER POLICE is now investigating more than 1,000 child sexual abuse suspects, following years of public criticism and institutional failings in tackling child sexual exploitation.

A new report by His Majesty’s Inspectorate of Constabulary and Fire & Rescue Services (HMICFRS) has revealed the force has made “significant improvements” in dealing with group-based sexual abuse and related crimes.
