Abstract

In this research, we designed and operated a microchip with an interchannel microstructure for separation of plasma from human whole blood and for metering and diluting the plasma. The plasma separation was based on both cross-flow filtration and sedimentation of red blood cells in the microchannels. Metering and diluting the plasma was based on volume control of liquid in the microchannels by syringe pumps. Simultaneous operations to separate, meter and dilute plasma obtained from whole blood were done in microchannels using this microchip, and plasma precisely diluted by a factor of 6 was generated without hemolysis in the microchannels in about 3 minutes. This microchip is easily connected with other microchannels and microfluidic devices for quantitative analyses.
