Short Report on Capillary Flow in Microfluidics

Subhadeep Mukhopadhyay


In this experimental work, a single SU-8 based glass microfluidic device is fabricated by maskless
lithography and indirect bonding technique. The sealing between glass lid and SU-8 based
microchannel structure is performed by indirect bonding technique during the hard baking. Dyed water
is prepared as working liquid to record the surface-driven capillary flow in microfluidics using a CMOS
camera catching 25 frames per second with a corresponding time-scale resolution of 0.04 second. This
work may be useful in commercial bioengineering applications.
