The ability of the Coronavirus to be infected 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 carrying out their work normally.

Testing is the only effective way to overcome this problem or at least to reduce it, but currently, available testing tools are not within everyone’s reach, as 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 can help bypass this.

The home testing device, consisting of sensors and Bluetooth, tests a blood sample and determines whether the sample has Covid-19 in just 10 minutes.

The device is similar to home blood glucose test kits and pregnancy tests, as it is similar to the former in that it can be used multiple times and the latter in the sense that it works through a drop on the sensor parts.

The Caltech team started building it by embossing a layer of graphene onto a sheet of plastic. Although graphene may be high-tech, it is cheap to manufacture. The sensors can be produced for 5 cents or less apiece, but electronics and other components push the price down to a few dollars.

How does it work?

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.
