复杂的生物分子，如液体中的蛋白质，在反应或蛋白质折叠中显示出特定的太赫兹动力学，如通过静态或动态吸收测量的。生物分子的复杂性质需要通过改变外部参数（如温度、压力、浓度和溶剂）的多模态方法来研究其频率、空间和时间特性。太赫兹光谱学可以为生命溶剂（即水）中生物动力学的其他光谱区域的现有技术提供新的和更深入的理解。为了更深入地了解水中复杂的液体或大分子，必须了解溶液的组成部分，其中可能含有盐，或者是氨基酸等较大分子的组分。虽然这项研究主要影响基础科学，但一些应用正在进行中，一些应用引起了工业界的兴趣，并且考虑到与医学相关的新应用的几条途径。在这篇文章中，我们回顾太赫兹光谱的解决方案，并集中我们的描述与小溶质，如盐和氨基酸的液体，并审查从水溶液中获得太赫兹数据的先决条件。
Complex biomolecules, such as proteins in liquids, show specific terahertz dynamics in reactions or in protein folding as measured by static or kinetic absorption. The complex nature of biomolecules requires investigating their frequency, space, and time characteristics via a multimodal approach that changes external parameters such as temperature, pressure, concentration, and solvents. Terahertz spectroscopy can add a new and deeper understanding to existing techniques in other spectral regions of the biological dynamics in the solvent of life, i.e. water. To understand more deeply complex liquids or macromolecules in water, it is essential to understand the building blocks of solutions, which may contain salts, or are components of larger molecules such as amino acids. Although this research mainly affects basic science, a few applications are in progress, some create interest in industry, and several pathways for new applications relevant to medical science are in view. In this article, we review THz spectroscopy of solutions and concentrate our description to liquids with small solutes such as salts and amino acids, and review the prerequisites for obtaining THz data from aqueous solutions.
