Got a new hoodie! Tuesday Brunch is not entirely sure how she feels about this development.

"A team of researchers at Washington University in St. Louis has developed a real-time air monitor that can detect any of the SARS-CoV-2 virus variants that are present in a room in about 5 minutes.

The proof-of-concept device was created by researchers from the McKelvey School of Engineering and the School of Medicine at Washington University...

The results are contained in a July 10 publication in Nature Communications that provides details about how the technology works.

The device holds promise as a breakthrough that - when commercially available - could be used in hospitals and health care facilities, schools, congregate living quarters, and other public places to help detect not only the SARS-CoV-2 virus, but other respiratory virus aerosol such as influenza and respiratory syncytial virus (RSV) as well.

“There is nothing at the moment that tells us how safe a room is,” Cirrito said, in the university’s news release. “If you are in a room with 100 people, you don’t want to find out five days later whether you could be sick or not. The idea with this device is that you can know essentially in real time, or every 5 minutes, if there is a live virus in the air.

How It Works

The team combined expertise in biosensing with knowhow in designing instruments that measure the toxicity of air. The resulting device is an air sampler that operates based on what’s called “wet cyclone technology.” Air is sucked into the sampler at very high speeds and is then mixed centrifugally with a fluid containing a nanobody that recognizes the spike protein from the SARS-CoV-2 virus. That fluid, which lines the walls of the sampler, creates a surface vortex that traps the virus aerosols. The wet cyclone sampler has a pump that collects the fluid and sends it to the biosensor for detection of the virus using electrochemistry.

The success of the instrument is linked to the extremely high velocity it generates - the monitor has a flow rate of about 1,000 liters per minute - allowing it to sample a much larger volume of air over a 5-minute collection period than what is possible with currently available commercial samplers. It’s also compact - about one foot wide and 10 inches tall - and lights up when a virus is detected, alerting users to increase airflow or circulation in the room.

Testing the Monitor

To test the monitor, the team placed it in the apartments of two Covid-positive patients. The real-time air samples from the bedrooms were then compared with air samples collected from a virus-free control room. The device detected the RNA of the virus in the air samples from the bedrooms but did not detect any in the control air samples.

In laboratory experiments that aerosolized SARS-CoV-2 into a room-sized chamber, the wet cyclone and biosensor were able to detect varying levels of airborne virus concentrations after only a few minutes of sampling, according to the study.

“We are starting with SARS-CoV-2, but there are plans to also measure influenza, RSV, rhinovirus and other top pathogens that routinely infect people,” Cirrito said. “In a hospital setting, the monitor could be used to measure for staph or strep, which cause all kinds of complications for patients. This could really have a major impact on people’s health.”

The Washington University team is now working to commercialize the air quality monitor."

Holy shit. I know it's still early in the technology and more testing will inevitably be needed but holy shit.

Literally, if it bears out, this could revolutionize medicine. And maybe let immunocompromised people fucking go places again

Also, for those who don't know, Nature Communications is a very prestigious scientific journal that focuses on Pretty Big Deal research. Their review process is incredibly rigorous. This is an absolutely HUGE credibility boost to this research and prototype

Last night I had a dream I woke up to find that my house had been turned into a Smart House with every wall being a digital screen including the roof so I could see it even laying on bed and the Siri voice said “Don’t worry. You are perfectly safe in your Apple Smart Home™️” knowing I have a BIG phobia of intruders especially at night and it continued with “Let’s explore the neighborhood from the comfort of your home” so it opened google maps and accidentally zoomed past a shitty jpeg of the girl from The Ring standing outside my house and it said “ignore that”. woke up laughing

i constantly think about that one youtube comment that was like "i never understood how humans learned to do complicated stuff like farm or make bread or brew alcohol until i watched speedrunners working together to break their favorite game". humans love working together to figure out extremely precise and nonintuitive processes to acheive a goal. i saw this article recently about how Neanderthals perfected a method of synthesizing a waterproof adhesive from birch bark by burying it in a pit with embers, and the whole time i was wondering how long it took to perfect that process. Barrier Skip took, what, a decade to get it right? Neanderthals could definitely figure out how to make sticky sap even stickier in that timeframe

Roomba kept crying because she couldn't find her spring toy and uh. Well, she had a good reason for it.

She's blind, she makes a lot of different sounds, and her poor social skills mean she tries to groom any other cat she bumps into. She doesn't bump into furniture or walls anymore but she used to. Whenever she bumped into something, she'd just turn around and keep going.
