Flow control in microfluidic chips: Material choice and smart design

摘要

This paper describes a model and experiments to validate it for the design of bubble free chambers and channels in microfluidic chips. When handling liquids in a microfluidic chip problems may arise with entrapping air or liquid. These air and liquid bubbles deteriorate the efficiency of the process on a chip and diminish the control of liquids in a chip. An analytical model was developed to design channels and chambers for specific liquids. Experiments showed that the model accurately predicts the flow behaviour inside the microfluidic chip.
