We described a method for electrophoretic separation of food dyes on a thread-based microfluidic analytical device. A cross channel thread-based microfluidic analytical device was fabricated and used to separate a mixture of food dyes. By controlling and adjusting the potentials applied onto four reservoirs, carmine and sunset yellow could be separated within 2 min. This method has the advantages of low cost, fast separation, and easy fabrication and operation, which make this very suitable for performing as a demonstration in universities. The students enjoyed this demonstration and presented some interesting and constructive questions after the demonstration, which indicated that the students were interested in the demonstration. This demonstration could also be modified to be a laboratory experiment which could be carried out within 3 h.

基于跨通道线程的微流体分离食品染料的装置

我们描述了一种在基于线程的微流分析设备上电泳分离食用染料的方法。制作了基于交叉通道线程的微流体分析设备，并将其用于分离食用染料的混合物。通过控制和调节施加在四个储层上的电位，胭脂红和日落黄可以在2分钟内分离出来。该方法具有成本低，分离快，易于制造和操作的优点，使其非常适合在大学中用作演示。学生们欣赏了这次演示，并在演示之后提出了一些有趣且富有建设性的问题，这表明学生对演示很感兴趣。该演示也可以修改为可以在3小时内进行的实验室实验。
