Experimental Demonstration on the Surface-Driven Capillary Flow of Red-Coloured Dyed Water in SU-8-Based Glass Microfluidic Devices

Subhadeep Mukhopadhyay

Abstract


In this research paper, four individual microfluidic devices are fabricated by the maskless lithography and indirect bonding technique. Negative photoresist SU-8 and glass are used in maskless lithography to fabricate the microchannels. PMMA dissolved in EC solvent is used as the adhesive material to bond the glass lids on the microchannels. Surface-driven capillary flow of dyed water in each device is recorded by a CMOS camera. This work will be useful to fabricate the SU-8-based microfluidic laboratory-on-a-chip systems for bioengineering applications.
