A rapid and low-cost test for the virus that causes COVID-19 has been developed by researchers in the US and Taiwan. Featuring a disposable testing cartridge and a reusable circuit board, the team’s portable system can detect the presence of the virus in fluid samples within just 1 s. By adjusting its design, the system could be adapted to test for other diseases.
