Microfluidic Flow of Aqueous Ethanol and Aqueous Isopropyl Alcohol in the SU-8 based Microchannel Bends

Abstract

In this work, a total of 8 individual SU-8 based microchannel bends as microfluidic devices are fabricated by the maskless lithography and indirect bonding technique according to the performed designs. Dyed aqueous ethanol (50% dyed water, 50% ethanol) and dyed aqueous isopropyl alcohol (50% dyed water, 50% isopropyl alcohol) are prepared and used as working liquids to test the fabricated microfluidic devices. A suitable CMOS camera is used to record each surface-driven microfluidic flow in the fabricated devices. This work may be useful to fabricate the commercial lab-on-a-chip systems by the negative photoresist SU-8.
