Paper Abstract

The optical characteristics of both the reduced and oxidized glutathione molecules in the range of O.2-2.5 THz have been investigated by the terahertz time-domain spectroscopy (THz-TDS) technology. The characteristic spectrum and optical parameter are obtained at the room temperature in nitrogen condition. The result shows that different samples have different absorption features. For the reduced glutathione, the absorption peaks centered at 0.85, 1.20, 1.52, 1.64, and 2.5 THz. While for the oxidized glutathione no obvious absorption peaks were found. The average refractive indices of two pure different glutathione samples (reduced and oxidized) are 1.77 and 1.89 respectively. The experimental results of two samples are compared and analyzed in this paper. This work has demonstrated significantly that THz-TDS can be used to identify two kinds of glutathione molecules, and can further be used to study other biological molecules in biological and biomedical engineering.
