Abstract

A novel microwave microfluidic sensor is offered for purity detection of medicine’s raw materials which is composed of two radial components and a PDMS microfluidic holder to apply the test samples. The basis of the sensing method is the shift in the resonance frequency and quality factor of the resonator in the presence of liquids with different complex permittivity. To investigate the performance of the proposed sensor, various solvents, binary mixtures of ethanol–water, and raw materials of 3 different medicines have been checked and a 980 MHz variation of resonance frequency, which provided a very high sensitivity equal to 0.53, was achieved for a complex permittivity range of 1–78.4. The proposed sensor has a small size, simple design, easy fabrication process, and very high sensitivity while it is fabricated on an FR4 substrate which decreases the total cost significantly.

用于检测药物原料纯度的新型微波微流控传感器

该传感器由两个径向组件和一个用于检测样品的 PDMS 微流控支架组成。传感方法的基础是在不同复介电常数的液体存在时谐振器共振频率和品质因数的变化。为了研究拟议传感器的性能，对各种溶剂、乙醇-水二元混合物和 3 种不同药物的原料进行了检测，在复介电常数范围为 1-78.4 时，共振频率的变化为 980 MHz，灵敏度非常高，等于 0.53。所提出的传感器体积小、设计简单、易于制造，灵敏度非常高，而且是在 FR4 基板上制造的，大大降低了总成本。
