Experimental Demonstration on the Recording of Capillary-Filled Microfluidic Devices Fabricated by Polymeric Material
Abstract
In this present experimental work, total 52 individual PMMA microfluidic devices are fabricated by maskless lithography, hot embossing lithography and direct bonding technique in a cleanroom laboratory. The selected working liquids are dyed water, dyed aqueous ethanol and dyed aqueous isopropyl alcohol and are prepared in a materials-science laboratory. Fabricated microfluidic devices are tested by the prepared aqueous working liquids, and each capillary-filled device after the surface-driven microfluidic flow is recorded by a CMOS camera in the same materials-science laboratory. In this work, leakage-free sealing is achieved in each fabricated microfluidic device according to the recorded snap-shot images. This present experimental work will be useful in commercial applications like bioengineering laboratory-on-a-chip systems.
