Effect of PMMA Micropillars on the Surface-Driven Capillary Flow of Dyed Aqueous Isopropyl Alcohol in PMMA Microfluidic Devices

Subhadeep Mukhopadhyay

Abstract


In this work, dyed aqueous isopropyl alcohol [60% isopropyl alcohol (IPA), 40% dyed water] is prepared as the working liquid. The effect of surface modification on the microfluidic flow of aqueous isopropyl alcohol (IPA) is studied in the polymethylmethacrylate (PMMA) microfluidic devices. The effect of surface area to volume ratio on microfluidic flow of aqueous isopropyl alcohol is also studied. The effect of microfluidic friction on microfluidic flow of aqueous isopropyl alcohol is also studied. This work will be useful to control the microfluidic flow of aqueous working liquids in lab-on-a-chip systems for different bioengineering applications.
