Experimental Demonstration on Microfluidic-Leakage in SU-8 based Glass Devices for Applications towards the Polymer Microfluidics

Abstract

Classical mechanics and quantum mechanics belong to the first quantisation in physics. Quantum
mechanics is dependent on quantum theory. Quantum field theory is the second quantisation in
physics. Fluid mechanics is a branch of classical mechanics (non-quantum). Therefore, fluid
mechanics is present at the first quantisation in physics. Bulk-fluidics (microfluidics), microfluidics
and nanofluidics are the three levels of fluid mechanics towards miniaturisation. In this experimental
work, the microfluidic-leakage is prominently demonstrated by fabrication of 12 individual leaky
microfluidic devices using the maskless lithography and improper indirect-bonding technique. Dyed
water is prepared and used as working liquid to demonstrate each microfluidic-leakage. A single
leakage-free SU-8 based glass microfluidic device is fabricated to demonstrate the leakage-free
microfluidic flow. In future, this experimental work may be helpful to realise the leakage-free
microfluidic devices for fabrication of microfluidic laboratory-on-a-chip systems.
Keywords: SU-8, Maskless lithography, Indirect bonding, Dyed water, Leakage
