This
situation is too severe by COVID-19. It is tough to find out the COVID affected
persons. How is it, by using the face masks we detect the COVID-19 affections?
Let’s see about it.
A team of
researchers from MIT and Wyss Institute for Biologically Inspired Engineering
at Harvard University have developed a wearable biosensor technology that can
help face masks detect COVID-19 in your breath.
This
biosensor was a lightweight, flexible substrate and textiles functionalized
with freeze-dried, cell-free synthetic circuits, with CRISPR- based tools,
embedded with colorimetric genetic circuits with cellulose substrate surrounded
by a fluid wicking and containment assembly made of flexible elastomers. These
prototypes were assembled layer-by-layer to form reaction chambers fluidically
connected to sample portals. Each layer is fabricated from skin-safe silicone
elastomer.
One of the
researchers from this team, Peter Nguyen said that they had brought a whole lab
into a small sensor that would work with any mask, and added that the
technology brought together the accuracy of the PCR tests, which are being used
as a standard COVID 19 tests globally.
The sensor
is activated with buttons and gives results on a readout strip within 90
minutes, researchers say. They add that levels of accuracy are comparable to
standard PCR COVID tests, which detect the virus' genetic material using a lab
technique called polymerase chain reaction.
These
wearable biosensors have now been attached to standard KN95 face masks to
successfully detect the presence of the SARS-CoV-2 virus in a person's breath,
according to a study published this week in Nature Biotechnology.
The
researchers first applied this technology to diagnostics by integrating it into
a tool to address the Zika Virus outbreak in 2015. This biosensor can also be
programmed and integrated into other garments so that on the go detection of
dangerous pathogens, such as bacteria, viruses, toxins and chemical agents. By
this detection method, we can easily identify the affected persons, and give
treatments faster and earlier, and save them.
