Abstract
A method of manufacturing a microfluidic chip includes providing an upper mold having multiple upper ribs extending along a second direction, and a lower mold having multiple lower ribs extending along a first direction different from the second direction, forming a forming material in a filling space defined by the upper and lower molds to provide a channeled plate having multiple upper microfluidic channels complementary in shape to the upper ribs, lower microfluidic channels complementary in shape to the lower ribs, and multiple thin film valves formed at intersections where the upper microfluidic channels intersect the lower microfluidic channels, separating the upper and lower molds, and covering the lower and upper microfluidic channels.
