The one that is most proven and ready to scale is based on a technology called LSPR. The team building it originally developed the device to monitor the status of the immune system, but it is easily adapted to detect the proteins on the surface of the virus instead of the proteins used for immune signaling. It’s able to detect even a very small number of viral particles, which is very important because we want to detect everyone who is contagious. Waiting for symptoms such as a fever or antibodies is too slow to stop the spread. What’s exciting is that they are creating a very sensitive test that can be mass produced at low cost (less than $1/test).
