METHOD FOR SENSITIVELY AND SELECTIVELY SENSING AVIAN INFLUENZA VIRUS USING TERAHERTZ ELECTROMAGNETIC WAVES AND DEVICE USED THEREFOR

摘要

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.

1. A method for sensing avian influenza virus in a sample, using a sensing chip, comprising:
applying the sample to a meta unit of the sensing chip; wherein the meta unit includes a pattern in a form of slits that serves to amplify a frequency corresponding to an absorption frequency of an avian influenza virus of interest; irradiating light in a form of terahertz electromagnetic waves to the sample on the meta unit of the sensing chip; and measuring the terahertz electromagnetic waves reflected from the avian influenza virus in the sample by measuring transmittance or frequency change of the terahertz electromagnetic waves to detect a subtype of the avian influenza virus.
