Abstract :
Terahertz time domain spectroscopy in the range 0.3-1.5 THz has been conducted for D-glucose at physiological concentrations from 25-200 mg/dL in pure water and in 0.9% saline by mass. The results show that the ions do not uniformly affect absorption of aqueous glucose, so NaCl ions should not be modeled simply as transparent holes in the water framework.
