A research team said it is paving the way for an easier detection of virus variants within indoor spaces.
Scientists have developed a novel air monitor with special technology that is said to quickly detect — within five minutes — if any of the virus variants that cause COVID-19 are lurking in an indoor room.
The results were published in Nature Communications in the journal’s July 10 edition as part of a collaboration between the engineering and medicine schools at Washington University in St. Louis, Missouri.
COVID PUBLIC HEALTH EMERGENCY IS OVER: WHAT IT MEANS FOR YOU
“This device can be installed in various settings such as hospitals, airports, office spaces, theaters or any crowded indoor location where the risk of virus transmission is high and ventilation may be inadequate,” first author Dr. Joseph Puthussery and co-author Dr. Carla Yuede told Fox News Digital in emailed comments.
Puthussery is a scientist at the Center for Aerosol Science & Engineering in the McKelvey School of Engineering at Washington University, while Yuede is an associate professor in the departments of psychiatry, neurology and neuroscience at Washington University School of Medicine.

Airborne aerosol detectors have difficulty detecting COVID-19 virus particles because the indoor air is so diluted that it’s “like finding a needle in a haystack,” said co-author Rajan Chakrabarty, PhD, researcher and associate engineering professor at Washington University.
But now, the scientists said they’ve created a real-time monitor that can detect any of the SARS-CoV-2 virus variants in a room within about five minutes.
Biosensor detects COVID-19 virus particles
The idea for the project started after the team wondered if a micro-immunoelectrode (MIE) biosensor that was previously developed for detecting a biomarker for Alzheimer’s disease could be converted into a detector for SARS-CoV-2.

“The MIE biosensor is a microelectrode containing an immobilized antibody (or nanobody) on the surface and uses an electrochemical method of detection,” Puthussery and Yuede told Fox News Digital in an email.
The researchers first developed the custom-built air sampler through simulations.
“The combination of the small size of the electrode and [the] specificity of the antibody/antigen interaction makes this biosensor very sensitive and specific to the target of interest,” they also said.
The team exchanged the antibody in the biosensor that recognizes a marker for Alzheimer’s disease to a “nanobody” — which recognizes the spike protein from the SARS-CoV-2 virus.
The group then integrated the biosensor into an air monitor that samples the indoor air at high speeds based on “wet cyclone technology.”

The researchers first developed the custom-built air sampler through simulations to discover the optimal size and the sampling flow rate necessary for capturing the “nano-sized” virus particles, Puthussery and Yuede told Fox News Digital.
Once inside the sampler, centrifugal force pushes the air outward to mix with fluids that line its walls.

These fluids contain the nanobody that detects COVID-19 virus particles — trapping the virus aerosols.
‘Virus collection efficiency’
Most commercial bioaerosol samplers have low flow rates — but the team’s air monitor has one of the highest flow rates, it said.
This means it can sample a larger volume of air over five minutes, the press release noted.
Its compact size, measuring only one foot wide by 10 inches tall, lights up when a virus is detected, alerting people to increased airflow or the circulation in the room, the press release added.

“We conducted experimental comparisons of the virus collection efficiency between the wet cyclone and two commercially available low-flow research-grade bioaerosol samplers,” the researchers told Fox News Digital.
“These experiments involved aerosolizing inactivated SARS-CoV-2 at various concentrations within a well-mixed sealed chamber.”
The monitor is at the proof-of-concept stage as of now. The research team is working to commercialize it.
They found the wet cyclone either outperformed or had comparable performance to the other samplers.
They validated their findings by collecting air samples from the self-isolating bedrooms of two individuals infected with COVID-19 — as well as a control room that was not contaminated with COVID-19 air.
The air monitor detected the virus particles in the seven samples in the rooms contaminated with COVID-19 virus.

And it did not detect any virus particles in samples from the virus-free control room.
‘Real-time data’
The monitor will help people in the future “easily recognize and avoid areas that have reported a high presence of the virus,” the researchers told Fox News Digital.
The team hopes to expand the air monitor capabilities to measure other common viruses that infect people as well, such as influenza, RSV and rhinovirus.

This will help people know when to wear masks when entering areas that consistently show the presence of a virus.
The device provides “peace of mind,” the researchers said.
“If you are someone who feels stressed attending a crowded public indoor event, you can access real-time data and be assured of your safety,” the researchers said.
Limitations of the device
One limitation of the monitor is “the high noise level (75–80 dB) during device operation, which can have an adverse effect on the health and comfort of the occupants of a building,” the researchers told Fox News Digital.

“Current efforts are underway to find economically feasible solutions to reduce the noise levels to <65 dB, such as using a low-noise motor and soundproofing the device exterior using an acoustic liner.”
The monitor is at the proof-of-concept stage as of now.
The research team is working to commercialize the air monitor in the near future.

Ask a doctor: ‘Is it ever OK to take someone else’s prescription medication?’
![Ask a doctor: ‘Is it ever OK to take someone else’s prescription medication?’](https://static.foxnews.com/foxnews.com/content/uploads/2024/06/pass-pills.jpg)
Most of us have, at some time or another, asked a friend or family member for some over-the-counter medicine to treat a headache or an upset stomach, as the dosage and directions are fairly universal.
But is the same protocol appropriate when it comes to taking someone else’s prescription medication?
The resounding answer from medical doctors is an emphatic “no.”
MEDICINE CABINET MUST-HAVES: 9 ESSENTIALS EVERY HOUSEHOLD SHOULD HAVE ON HAND
There are specific reasons why.
“Taking someone else’s prescribed medication can be very harmful,” LaTasha Perkins, M.D., a family physician at Medstar Georgetown University Hospital in Washington, D.C., told Fox News Digital.
Doctors agreed that sharing prescription medications with others is a bad idea. (iStock)
“You need to take only your own medicine and not someone else’s, because so much goes into figuring it out.”
Numerous considerations are involved in prescribing medication to a patient, Perkins said — including health status, medical history and blood work — which can be completely different from one person to the next.
Even if you take the same medication as someone else, the other person may be on a different dose of it, the doctor noted.
TRAVELING INTERNATIONALLY? IT COULD BE ILLEGAL TO BRING ALONG THESE MEDICATIONS, ACCORDING TO A PHARMACIST
“A lot of medications also look and sound the same, so you have to take what was specifically prescribed to you,” she cautioned.

Drug interactions present another concern.
“If you’re taking vitamins or any other medication that may interact with a prescription medicine, that should be taken into account when tailoring your prescription,” Perkins said.
Allergies are yet another key consideration, the doctor warned, as some people are allergic to the additives in medications.
“There’s a reason the medication is prescribed — because it’s personalized to each individual based on a variety of health factors,” Perkins said.

Chad Weston, M.D., a physician with Novant Health Oceanside Family Medicine & Convenient Care – Brunswick in Shallotte, North Carolina, agreed that taking a medication prescribed to a different individual, even for seemingly similar symptoms, can be harmful and have unintended consequences.

“These consequences range from severe allergic reactions to medication interactions and overdosing, causing damage to organs such as the liver and kidneys,” he said in an interview with Fox News Digital.
Instead of seeking symptom relief by taking someone else’s medication, you should see a doctor to get an accurate medical diagnosis and prescription, Weston advised.

In the event that you’re traveling and don’t have your medicine with you, Perkins said the best thing to do is call your doctor.
“If you don’t have your medicine, we can call it into a pharmacy wherever you are,” she said.

“This is why it’s so important to have a family physician,” she said.
“Having a relationship with your doctor can help you navigate situations like this.”
