The test is based on a gene-editing technology known as CRISPR, and the researchers estimated that the materials for each test would cost about $6. It proved to be a workhorse for biological research, as well as for forensic DNA tests and other applications. In January, when scientists discovered the coronavirus that causes COVID-19, they used its genetic sequence to create PCR tests for it. Some companies have invented self-contained devices that test for the coronavirus and deliver a result in minutes. To see if the coronavirus is present, the researchers devised a procedure similar to a pregnancy test: They stuck a piece of paper in the tube.
