Microfluidic Devices Controlled by Surface Tension

摘要

The present invention relates to a microfluidic device that is controlled by surface tension, combines the upper substrate and the lower substrate in the microfluidic device to control fluid and the reaction, the lower substrate includes a first fluid and in which the second fluid is stored in each a first reservoir chamber and the second reservoir the first flow stopping part and the second flow stopping part for stopping the chamber, the first reservoir chamber and the and detection chamber, which is connected to the second reservoir chamber, the first fluid or the movement of the second fluid and a first and a flow delay part of the fluid or reducing the moving speed of the second fluid, that the reaction is connecting the flow delay part with the disposal chamber such that the first fluid or the second fluid is disposed of the chamber and the fluid is moved to be disposed of complete comprises a flow path, and the upper substrate and includes a detection to measure the biochemical reaction in the detection chamber, the first fluid is moved to the detection chamber by capillary force occurs primary biochemical reactions, certain If the elapsed time after the second fluid is introduced into the detection chamber by capillary force characterized in that the replacement and secondary biochemical reaction of the first fluid occurs. Accordingly, it is no need for additional equipment and power supplies, compactness, effective cell upset possible, and not, as well as to increase the manufacturing yield and at the same time reducing the manufacturing costs, the use of the apparatus during failure almost.
