Abstract

In this experimental work, a single microchannel bend is fabricated by maskless lithography, hot embossing lithography and direct bonding technique. Polymethylmethacrylate (PMMA) is the chosen optically transparent polymeric material to fabricate the microchannel bend inside the cleanroom laboratory. Dyed ethanol is prepared as working liquid. CMOS camera is used to record the surface-driven capillary flow of dyed ethanol in the fabricated microchannel bend. Effect of centrifugal force on surface-driven capillary flow of dyed ethanol is studied. This work will be useful in applied chemistry.
