Experimental Demonstration on Polymer based Microfluidics at the First Quantisation in Physics

Subhadeep Mukhopadhyay

Abstract

Difference between classical mechanics and quantum mechanics is the first quantisation in physics as the quantum theory is first quantisation in physics. Quantum field theory is the second quantisation in physics. Principles of fluid mechanics belong to the classical mechanics (non-quantum). Hence, fluid mechanics is present at the first quantisation in physics. Bulk-fluidics, microfluidics and nanofluidics are the levels of fluid mechanics from the aspects of miniaturisation. In this experimental work, a single polymethylmethacrylate (PMMA) based microchannel bend as microfluidic device is fabricated by maskless lithography, hot embossing lithography and direct bonding technique. Dyed water is prepared and used as working liquid in this work. A CMOS camera is used to capture the surface-driven microfluidic flow of dyed water in the fabricated device. In future, this experimental work may be helpful to realise the nanofluidic phenomena in nanofluidics.
