Abstract
Disclosed herein are a method and device for sensing avian influenza viruses, using terahertz electromagnetic waves. By the method, even a trace amount of avian influenza viruses in a liquid state can be accurately discriminated and sensed, with high sensitivity and selectivity, using a sensing chip that works in a terahertz electromagnetic wave band. Using the method, avian influenza viruses even at low concentrations can be accurately analyzed with high sensitivity and selectivity in which terahertz electromagnetic waves are irradiated onto avian influenza viruses through a sensing chip having a meta unit in which a pattern is formed to amplify a frequency corresponding to an absorption frequency of an avian influenza virus of interest.
