Abstract: The present specification relates to a device and method capable of determining a coronavirus mutation using a highly sensitive label-free terahertz electromagnetic wave metamaterial sensor, and a device for diagnosing a coronavirus disease-19, amd the device can specify the amino acids of a virus belonging to the genus coronavirus having an excellent absorption in a terahertz band, and the metamaterial can amplify the corresponding signal, and the problem of coffee ring formation, which hinders the measurement and analysis in the conventional measurement and analysis of solution-based samples, can be solved by the method in which a sample containing coronavirus is applied to the surface of a metamaterial, and the optical constant value of the sample is analyzed, so that it is possible to more quickly and accurately determine the coronavirus mutation, and furthermore, there is an excellent effect in diagnosing a coronavirus disease-19.
