Effect of Circular Polyimide Micropillars on Surface-Driven Capillary Flow of Dyed Working Liquids inside the SU-8 based Glass Microfluidic Devices

Subhadeep Mukhopadhyay

Abstract


In this experimental work, total 8 individual SU-8 based glass microfluidic devices are fabricated using Mukhopadhyay’s own hands-on completely. Maskless lithography and indirect bonding technique are the methods to fabricate these devices. A CMOS camera catching 25 frames per second with a corresponding time-scale resolution of 0.04 second is used to record the surface-driven capillary flow in each device. Dyed water and dyed ethylene glycol are the selected and prepared dyed working liquids. Each recorded flow is analysed to determine the fluid flow characteristics in the fabricated microfluidic devices. This experimental work will be suitable to fabricate the SU-8 based laboratory-on-a-chip systems for commercial applications.
