Helsinki Airport Starts Using Dogs To Detect Covid-19 In Pilot Program

In April, U.K. researchers were training dogs to detect the scent of COVID-19, hoping they could help stop its spread. Now, four Covid-19 sniffer dogs have begun work at Finland’s largest airport, Helsinki airport, in a state-funded pilot program which will last four months. Finnish researchers hope the scheme will...

A team of scientists at the Department of Energy’s Pacific Northwest National Laboratory created a new kind of micelle, one that is stamped on the surface with copies of an imprinted particle for SARS-CoV-2.

The team filled micelles with a salt capable of creating an electronic signal but that is quiescent when packed inside a micelle. When a viral particle interacts with one of the imprinted receptors on the surface, the micelle pops open, spilling the salt and sending out an electronic signal instantly.

The team estimates that the technology can pluck one viral particle out of billions of other particles. The detector is so sensitive that the team had a challenging time identifying the lower limit. The team used both inactivated SARS-CoV-2 viral particles and the virus’s spike protein in its tests.

While the technology detects the virus within a millisecond, the device takes an additional minute to run quality-control software to confirm the signal and prevent false alarms.

Pfizer buys Brisbane company behind COVID-19 diagnosis app for $179m

Recent studies had shown the app had a 92 per cent success rate in diagnosing the virus among symptomatic patients, but more clinical trials were needed for it to gain regulatory approval

So either this app(lication) will be a gamechanger, or go the way of Theranos..
