Recording of Surface-Driven Laminar Flow in Dual Sudden Expansion Microchannel of a Single SU-8 based Glass Microfluidic Device

In this work, the SU-8 based glass microfluidic device is fabricated by maskless lithography and indirect bonding technique. A dual sudden expansion microchannel is designed and fabricated inside this fabricated glass microfluidic device. Dyed water is prepared as working liquid by mixing commercially available food dye with distilled water. The surface-driven laminar flow of dyed water inside the fabricated microchannel is recorded by a CMOS camera. This experimental work is useful in commercial bioengineering applications.
