Econology still well in advance ... but alone and without the difficult money to compete with MIT !!!

US scientists test heated mask that would destroy coronavirus

Research is still in progress but the first results look promising. In the United States, engineers from the Massachusetts Institute of Technology (MIT) announced on October 21 that they had developed a mask that could deactivate the virus by using heat.

While the masks we currently use, whether fabric or plastic, only work to reduce the spread of the virus, this new mask would be even more effective.

The system is as follows: a copper mesh heated in the mask by means of a battery enables viral particles to be neutralized by heat during respiration.

Prototypes already built but a need for scientific validation

"Such a mask could be very useful for healthcare workers, as well as for the general public in situations where social distancing cannot be respected such as in crowded public transport," the researchers write.

While this experiment has been underway since March, several prototypes of these masks have already been built. But the experimentation has yet to be evaluated by scientific and medical experts.

"And of course, we must be vigilant about the safety as well as the comfort for the users of the mask", added Samuel Faucher, graduate of the institute and main author of the research. In all likelihood, these next-generation masks are expected to cost more than surgical masks

Obviously there is a team behind it is much more complex than what I calculated above ... but I am proud because 20.7W is exactly what I had calculated and measured above in the spring! Just like the temperature between 90 and 110 ° C ... : Cheesy: : Cheesy: : Cheesy:

Message received by email:
Bonjour à tous
I want to present to you a small study on a type of reusable mask using UVC technology to reduce the burden of covid. It is already widely used to sterilize empty rooms with ozone. The advantage for a mask is to be able to breathe freely because there is no mechanical filter. The availability of uvc led for the general public makes it possible to consider on-board solutions. It has been established that the main transmission of the virus is via aerosols. I would like to have your opinion on the acceptability and possibly some help to allow me to continue. thank you for your visit

http://uvcov.fr/


The site is interesting and very complete, several prototypes have been made:

Basic principle

It is well illustrated by the oracle lightning research site which has defined the irradiation parameters and provides maximum information and guarantees. A Chinese manufacturer also gives interesting technical information. These values ​​need to be measured with a radiometer.
The irradiation of the air that will be sucked in occurs during the exhalation. It lasts on average, at rest for an unstressed grandpa. 3s. The average volume of air to be treated for each cycle is estimated at 0.5 l. The valves make it possible not to mix the aspirated and expelled air. When you exhale, the air in the suction duct is at rest and the microdroplets are deposited in part by an electrostatic effect on the walls of the tube. This effect will be amplified with the 12 volt models.
UVC wavelength close to 275 nm, minimum irradiation energy 1 J / cm2. Or more than 300mw during the 3 seconds.
No ozone creation The UV / ozone sources rotate between 185 and 254 nm, which leaves enough safety margin.
These masks are a passive protection against direct projections like closed visors and which can be disinfected with an alcohol wipe. Their objective is to eradicate the virus as much as possible in its airborne form. Reduce the viral load, which partly determines the severity of the infection.

MIT is innovating yet again with another type of intelligent anti-covid mask!

MIT created mask that can detect covid and other viruses in 90 minutes

What if we put a whole molecular analysis laboratory in a mask? This reflects, in the idea, the work of a team from MIT and Harvard. They have developed a mask capable of detecting the presence of the coronavirus and other infectious agents. The result is obtained in 90 minutes.

Engineers from MIT and Harvard's Wyss Institute have competed in ingenuity to develop a prototype face mask that can single-handedly detect contact with the SARS-CoV-2 coronavirus and other infectious agents . This research was published this Monday, June 28, 2021 in Nature Biotechnology. It is a biotechnology based in part on the CRISPR principle, the famous genetic scissors. Here is how it works.

As sensitive as PCR tests?

The mask developed by MIT and Harvard engineers aims to detect both whether the person wearing it is infected and whether they have been exposed to the virus in their environment, thanks to sensors positioned both inside and outside.

The project is based more specifically on biological sensors that react to biomolecules, in this case the nucleic acids of viruses and bacteria. The sensors are lyophilized, that is to say dehydrated, which allows them to "survive" without degrading, for months. This little detail is crucial, because it is what makes the prototype viable in a very "practical" way - no need to carry living cells on you, in short.

The sensors are therefore, by default, biologically deactivated. To activate them, all you have to do is press a button on the mask, which releases a tiny amount of water which rehydrates the sensors. These will then be ready to react to the targeted DNA or RNA sequence - either by reacting to the breath molecules inside the mask, or by reacting to the droplets received outside.
The mask developed in this work is worn normally, but has a small button that allows you to launch the detection. // Source: Wyss Institute at Harvard

The result takes 90 minutes to arrive after activating the process. The detection of an infectious agent is displayed in two possible ways, in the prototype: a signal by a change of color, visible to the naked eye; or else a fluorescent signal readable with a portable spectrometer. The result could also be connected to a smartphone to directly transmit the result to an app. This makes it possible to know where and when the exhibition took place.

"This test is as sensitive as the reference one, namely the very sensitive PCR tests, but it is as fast as the antigenic tests which are used for a rapid analysis of Covid-19", explain the creators of this prototype on the site from MIT. The detection technique itself is based on compounds nicknamed SHERLOCK (Specific High-sensitivity Enzymatic Reporter unLOCKing). Scientists simply ingeniously reused a CRISPR enzyme. CRISPR genetic scissors work with an enzyme that targets a specific genetic sequence in order to cut it. For SHERLOCK, this enzyme is used to detect a viral genetic sequence, in order to help signal its presence. Part of the detection process also works a bit like a PCR test, by amplifying the target sequence.

A whole portable lab in textiles

The prototype is not intended only for the coronavirus. In fact, researchers had started working on it before the pandemic. But with the emergence of the Covid-19 disease and the health crisis, the researchers decided to direct their work towards this pathogen. Ultimately, the mask was developed to detect a variety of infectious agents: Ebola, Zika, influenza, the SARS-CoV-2 coronavirus, and even organophosphate nerve agents (very dangerous chemicals that attack nerve cells) .

Before the pandemic and mask-like development, the research team was looking for different textiles to incorporate their wearable detection mechanism project. Sifting through materials compatible with freeze-dried biological sensors, the researchers eventually identified "a few that are very widely used" in clothing, such as the combination of polyester and other man-made fibers. They carried out a first conclusive test on a gown in which 30 sensors were integrated. By releasing “contaminated” splashes on the gown, they could see that the detection was working well - the sensors displayed the color associated with the infectious agent.

During the pandemic, they simply applied this principle to masks, in this case of the FFP2 type. The sensors are protected by a silicone elastomer, and associated with the famous small water tank which allows them to be hydrated to launch the detection. Here again, the tests were conclusive.

"In these experiments, we finally reduced the functionality of advanced laboratories in molecular analysis to a format compatible with wearing of clothing, for a variety of applications," summarize the scientists at MIT. They have filed for a patent and are planning an upcoming commercialization, in particular for the face mask, which comes closest to a product intended for sale.

No need for MIT when trained dogs are enough to detect an infected.
