  • Thread-based microfluidic guiding system
    Patent number: 9146212
    Abstract: A thread-based microfluidic guiding system is provided and includes a substrate, two fiber threads arranged on the substrate in a cross manner. The two fiber threads are used as physical guiding pathways to guide a sample fluid and a buffer fluid, respectively. The two fiber threads have capillary action, so that the sample fluid, the buffer fluid or a mixture fluid thereof can flow along fiber surfaces of the two fiber threads, which can be pre-treated by plasma. The thread-based microfluidic guiding system of the present invention is different from recessed microfluidic channel structures, and can simplify system structure, lower manufacture cost, accelerate detection operation and enhance detection sensitivity.
