Effect of Surface Modifications on the Meniscus Velocities of Dyed Water in PMMA Microchannels
Abstract: In this work, author has fabricated the polymethylmethacrylate (PMMA) microfluidic devices to study the effect of surface modification techniques on surface-driven capillary flow. Maskless lithography, hot embossing lithography and direct bonding technique are used to fabricate the PMMA microfluidic devices. The effect of static water contact angle on surface- driven capillary flow is studied in the fabricated devices. The effect of the arrays of square PMMA micropillars on surface-driven capillary …
