    摘要: A microchannel chip and a dilution method using the same capable of continuously diluting the diverse concentrations of solution by one time fluid injection using the microfluid technology are provided. The microchannels are formed in a plastic chip using the microfluid technology, and a width, a sectional area, or a length of the microchannel is regulated so that the flow rate of a diluted solution (e.g., buffer solution) and a sample (e.g., chemicals or medicament) is controlled. The diluted solution and the specimen are mixed in the mixing channel according to the flow rate, thereby diluting the sample. Such a diluted solution is mixed again with a diluted solution, carrying out the dilution. With the repeated dilution processes, continuously diluted solution is obtained.
