- Abstract
- A novel polymer microfluidic chip for sample exchange via capillary force and a test of the device for an enzyme-catalyzed precipitation reaction are described. All the fluidic actuations in the device were run by a time-planned flow sequence and accomplished by only capillary force. The chip accomplishing self-replacement of samples was realized by designing the channels with theoretically derived equations for the capillary flow and stop. The chip was fabricated with polymer replication techniques which are suitable for the device fabrication with low price and single use. The test for a biochemical analysis using biocatalyzed precipitation reaction with the chip showed desired outcome. The presented microfluidic method would be applicable to various biochemical lab-chips with integrated washing steps or fluid replacement steps.
