Provided is a coronavirus detection method which is suitable for a coronavirus disease 2019 (COVID-19) detection. The method includes the following steps. A field-effect transistor-based biosensor (BioFET) platform is provided, wherein the BioFET platform includes a BioFET and a sensor card. The sensor card is detachably connected to the BioFET, wherein the sensor card includes a plurality of sensors and each of the plurality of sensors includes a response electrode. A nucleic acid probe specific to a nucleic acid sequence of COVID-19 virus is immobilized on a surface of the response electrode. A test solution is placed on the response electrode of the sensor card. A pulse voltage is applied to the response electrode, and a detection current generated from the sensor card is measured. |
