A thread-based microfluidic channel device was firstly designed and manufactured by our-selves .The device is composed of a support ,loading systems ,reservoir devices and a microfluidic terminal fixer .They can be assembled and moved freely ,and fit any microfluidic pattern and the wicking rate of the fluid can be controlled .This microfluidic channel device was applied to the separation of mixed dyes by sin-gle channel ,the determination of nitrite in soil and water by Y-shaped channel and the simultaneous deter-mination of copper and zinc in soil by triple-channel . The self-made microfluidic device is low-cost and portable .
