Passive Capillary Flow of Dyed Ethanol for Nanofluidics

Subhadeep Mukhopadhyay

Abstract


In this experimental work, a single polymethylmethacrylate (PMMA) microchannel bend as microfluidic device is fabricated by maskless lithography, hot embossing lithography and direct bonding technique. Dyed ethanol is prepared and used as working liquid in this work. A CMOS camera is used to capture the surface-driven capillary flow of dyed ethanol in the fabricated PMMA microchannel bend. In future, this experimental work may be useful to establish the nanofluidic flow characteristics in nanofluidics using proper fabrication techniques with appropriate recording systems.
