Abstract

AbstractPolymethylmethacrylate (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.Keywords: Sudden Expansion, Aqueous Ethanol, Capillary Flow, PMMACite this ArticleSubhadeep Mukhopadhyay.
