Abstract

The polymethylmethacrylate (PMMA) microfluidic devices are fabricated by the maskless lithography, hot embossing lithography and direct bonding technique. The effects of liquid viscosity, surface wettability and channel aspect ratio on the surface-driven capillary flow of non-aqueous working liquids are studied in the fabricated PMMA microfluidic devices. The working liquids are ethylene glycol, isopropyl alcohol (IPA) and ethanol. These experimental studies will be useful to manipulate different non-aqueous working liquids inside the microfluidic lab-on-a-chip systems.
