Short Report on the Passive Microfluidic Flow of Ethanol towards Nanofluidics in Nanotechnology

Subhadeep Mukhopadhyay

Abstract


In this experimental work, a single gradual expansion microchannel is fabricated by polymethylmethacrylate (PMMA) as polymeric material using author’s own hands-on in the maskless lithography, hot embossing lithography, and direct bonding technique. Dyed ethanol is prepared as working liquid. A CMOS camera catching 25 frames per second with a corresponding time-scale resolution of 0.04 second is used by author to record the surface-driven microfluidic flow of dyed ethanol in the fabricated microfluidic device. Leakage-free surface-driven microfluidic flow is recorded by author due to proper direct bonding technique. The surface-driven microfluidic flow is governed due to the thermodynamic effect. This experimental work may be useful in the commercial
bioengineering applications.
