Experimental Demonstration on Microfluidic Capillary Flow of Red Dye in Photoresist based Glass Microfluidic Devices
Abstract: In this experimental work, a set of three individual SU-8 based glass microfluidic devices are fabricated by maskless lithography and indirect bonding technique in leakage-free conditions. Commercially available red coloured food dye is used as the selected working liquid. The microfluidic leakage in other set of two leaky microfluidic devices is experimentally demonstrated. Microfluidic devices should be fabricated at leakage-free conditions to achieve exact fluid flow characteristics. The effect of …

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
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 …
