Surface-Driven Capillary Flow of Dyed Aqueous Ethanol in the PMMA Microchannel Fabricated by Maskless Lithography, Hot Embossing Lithography and Direct Bonding Technique

Abstract

Abstract

Polymethylmethacrylate (PMMA) as polymer is used to fabricate a dual sudden expansion microchannel by the maskless lithography, hot embossing lithography and direct bonding technique inside the cleanroom laboratory. Dyed aqueous ethanol (90% dyed water, 10% ethanol) is used as working liquid to record the surface-driven capillary flow in the fabricated microfluidic device using a CMOS camera catching 25 frames per second with a corresponding time-scale resolution of 0.04 second. This experimental work will be useful to fabricate the polymer laboratory-on-a-chip systems for different microfluidic applications.
