Abstract
Disclosed herein are a method and a device for sensing sugars, using terahertz electromagnetic waves. By the method, even a trace amount of sugars 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, sugars even at low concentrations can be accurately analyzed with high sensitivity and selectivity in which terahertz electromagnetic waves are irradiated onto sugars 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 sugar of interest.
