Abstract

In this paper, we designed a sandwich microfluidic chip and combined it with terahertz technology to study the effects of histidine on the absorption characteristics of terahertz waves. By observing the intensity of its time domain spectrum in the range of 0.2-2.6 THz, it was found that the terahertz transmission gradually decreased with the increase of histidine concentration. In addition to this, the characteristic absorption peaks of histidine and its aqueous solutions were measured in the experiment using the terahertz time-domain system and the vibrational modes of their theoretical absorption peaks were attributed using Gaussian16 software. In the future, we will delve into the absorption peaks of liquid amino acid solutions and compare them to solid amino acids. As far as possible, terahertz technology is used to identify liquid amino acids in solution.
