The Journal Nature Biotechnology published research on Monday. The study showed that miniature sensors interweaved with fabrics for masks and jackets can provide immediate info. The information would be regarding exposure to disease pathogens like the coronavirus.
The super-sensitive test has been limited to laboratory use only. These are being projected with smart wearables which are more than Fitbit or Apple watch features stated co-author Peter Nguyen. The research is published by a group of scientists at the Wyss Institute at Harvard University.
He said, “The concept is similar to how our skin works, where you automatically sense your environment with exquisite sensitivity without needing to actively participate in the details of the process itself.”
As per the recent study, scientists were able to recreate and dry freeze the cell parts. The frozen cell can detect dangerous microorganisms. They are then reactivated by adding water like a “pack of instant noodles.”
Previously such tests were based on living cells, which researchers claimed were too sensitive and harmful in a non-medical environment. The researchers used cell-free reactions in the recent study. This contains the tools of a living cell without the cell itself.
The sensors can be freeze-dried and stored for months until they are ready to be activated as they are not alive. The researchers demonstrated that CRISPR gene editing-tech sensors can match laboratory virus detection. This can also be woven into wearable fabrics.
According to Nguyen, wearable sensors are beneficial to “anyone operating in an area where they can be exposed to infections or toxins.” A prototype Covid-19 testing mask with a patch of sensors attached to a pad that catches the user’s breath particles is being developed by researchers.
The wearer pierces a small pouch on the mask after at least 15 mins of use, and water wicks the sample into the sensor for analysis. The result is displayed on a strip on the mask. The researchers have also designed a jacket for workers working in dangerous situations. The jacket can resist a liquid “exposure event.”
The long-run garments can be used by normal people, especially when we are facing numerous local outbreaks. It is easy at home-testing.
Scientist at Northwestern University has designed a flexible mini cardiac pacemaker. It is completely absorbed by the body after its purpose is fulfilled. The authors are hoping for a better future as it will provide solutions for patients requiring temporary pacing tech.
