The ability of the Corona virus to infect during the incubation period inside the body is one of the most important reasons for the difficulty of combating it and limiting its spread, especially since some people who suffer from it do not know that they are infected, there are thousands of people who do not suffer from symptoms while they are doing their work normally.
The test is the only effective way to overcome this problem or at least to reduce it, but the currently available test tools are not affordable for everyone, because they are expensive and take days to give results.
A new device developed at the California Institute of Technology called the SARS-CoV-2 RapidPlex (SARS-CoV-2 RapidPlex) could help bypass this.
The home test device, consisting of sensors and bluetooth, tests the blood sample and determines if the sample submitter has COVID-19 in just 10 minutes.
The device is similar to a home glucose test kit and pregnancy tests, in that it is similar to the former in that it can be used several times and the latter in the sense that it works through a drop on its sensor parts.
The Caltech team began building it by engraving a layer of graphene onto a sheet of plastic.
Although graphene may be high-tech, its manufacture is cheap. Sensors can be produced for 5 cents or less per piece, but electronic devices and other components push the price up to a few dollars.
How it works?
When blood is placed on the graphene-etched sensor, the tiny pores on its surface stabilize the coronavirus and antibodies.
Users have to do a little biochemical treatment, adding a drop of solution one minute after adding the sample, wait another minute, then wipe it off, then add another drop.
