Abstract
Disclosed herein are a method and device for sensing pesticide residues, using terahertz electromagnetic waves. By the method, even a trace amount of pesticide residues on objects such as fruits 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, pesticide residues even at low concentrations can be accurately analyzed with high sensitivity and selectivity in which terahertz electromagnetic waves are irradiated onto pesticide residues through a sensing chip having a meta unit in which a pattern is formed to amplify a frequency corresponding to an absorption frequency of a pesticide residue of interest.
