Short Review on Thermodynamic Effect to Generate the Surface-Driven Microfluidic Flow in Fluid MechanicsBy Subhadeep Mukhopadhyay
Abstract: The levels of fluid mechanics are bulk-fluidics (macrofluidics), microfluidics, and nanofluidics in thedirection of miniaturisation. In this review, a brief account is provided to describe the thermodynamiceffect behind the generation of any surface-driven microfluidic flow in the regime of fluid mechanics.Also, an experimental demonstration on the surface-driven microfluidic flow of dyed water isprovided corresponding to the SU-8 based glass microfluidic devices fabricated by masklesslithography and indirect bonding technique. A prominent …

Experimental Demonstration on Microfluidic-Leakage in SU-8 based Glass Devices for Applications towards the Polymer MicrofluidicsBy Subhadeep Mukhopadhyay
Abstract: Classical mechanics and quantum mechanics belong to the first quantisation in physics. Quantummechanics is dependent on quantum theory. Quantum field theory is the second quantisation inphysics. Fluid mechanics is a branch of classical mechanics (non-quantum). Therefore, fluidmechanics is present at the first quantisation in physics. Bulk-fluidics (microfluidics), microfluidicsand nanofluidics are the three levels of fluid mechanics towards miniaturisation. In this experimentalwork, the microfluidic-leakage is prominently demonstrated by fabrication of 12 …

Short Report on Capillary Motion of Dyed Ethylene Glycol for Application towards the Gas Flow in MicrofluidicsBy Subhadeep Mukhopadhyay
Abstract: In this experimental report, a couple of SU-8 based glass microfluidic devices are fabricated bymaskless lithography and indirect bonding technique. Each device is tested by the prepared dyedethylene glycol as working liquid. The microfluidic-leakage is recorded in the surface-drivencapillary motion of dyed ethylene glycol due to improper indirect bonding technique. The leakagefreesurface-driven capillary motion of dyed ethylene glycol is recorded due to proper indirectbonding technique. This experimental work is performed …

Experimental Studies on the Surface-Driven Microfluidic Flow of Dyed Ethylene Glycol in Polymer Microfluidic DevicesBy Subhadeep Mukhopadhyay
Abstract: In this experimental work, three individual microfluidic devices are fabricated by polymethylmethacrylate (PMMA) using maskless lithography, hot embossing lithography and direct bonding technique. Straight microchannel having uniform width along entire channel length is the chosen design of microchannels before fabrication. Dyed ethylene glycol is prepared and used as working liquid. Effect of channel aspect ratio on surface-driven capillary flow of dyed ethylene glycol is studied. CMOS camera is used to …
