Experiments to Control the Surface-Driven Microfluidic Flow of Dyed Water in Straight PMMA Microchannels Fabricated by Maskless Lithography, Hot Embossing Lithography and Direct Bonding Technique

Subhadeep Mukhopadhyay

Abstract


Total six individual straight microchannels are fabricated by maskless lithography, hot embossing lithography and direct bonding technique using author’s own hands-on completely inside the cleanroom laboratory. Polymethylmethacrylate (PMMA) is the selected polymeric material to fabricate these straight microchannels. Dyed water is prepared as working liquid to record and study the microfluidic flow characteristics inside these fabricated microchannels. Air dielectric barrier discharge (DBD) plasma processing is the surface modification technique in this experimental work to vary the static contact angle of dyed water on the inner surfaces of these fabricated microchannels. This experimental work will be useful to fabricate the microfluidic laboratory-on-a-chip systems for bioengineering applications.
