A COVID-19 sensor developed at Johns Hopkins University could revolutionize virus testing by adding accuracy and speed to a process that frustrated many during the pandemic.
In a new study published today in Nano Letters, the researchers describe the sensor, which requires no sample preparation and minimal operator expertise, offering a strong advantage over existing testing methods, especially for population-wide testing.
