Report on Microfluidic Flow of Dyed Working Liquids inside the Polymeric Devices
Abstract
In this experimental work, a single SU-8 based glass microfluidic device is engineered by the maskless lithography and indirect bonding technique. Also, total nine individual polymethylmethacrylate (PMMA) based microfluidic devices are fabricated by maskless lithography, hot embossing lithography, and direct bonding technique. Dyed ethylene glycol, dyed ethanol, and dyed aqueous isopropyl alcohol (50% water, 50% IPA) are prepared and used as working liquids to record each surface-driven microfluidic flow. The filling time corresponding to dyed ethylene glycol is higher than that of other two working liquids. The filling time of each working liquid is higher corresponding to the microfluidic device containing square PMMA micropillars of larger side length. This experimental work is suitable for bioengineering applications related to the laboratory-on-a-chip systems.
