The vibrational energy levels of many biomolecules correspond to the terahertz band; thus, terahertz technology can be used to identify these substances. Moreover, as the biological activity of most biomolecules can be observed only in aqueous solution, the characteristics of such biomolecules must be studied in aqueous solution. In this study, a simple microfluidic chip, a temperature control device and a strong electric field device were designed to study the terahertz absorption characteristics of guar gum for different temperatures, concentrations and electric field exposure durations, thus enabling the use of terahertz technology to analyse the characteristics of guar gum.

微流控技术测定瓜尔胶的太赫兹吸收特性

许多生物分子的振动能级对应于太赫兹波段；因此，太赫兹技术可用于识别这些物质。此外，由于大多数生物分子的生物活性只能在水溶液中观察到，因此必须在水溶液中研究此类生物分子的特性。本研究设计了一个简单的微流控芯片、一个温度控制装置和一个强电场装置来研究瓜尔胶在不同温度、浓度和电场暴露时间下的太赫兹吸收特性，从而使太赫兹技术能够用于分析瓜尔胶的特性。
