Surface-Driven Capillary Flow on Microchannel Surface Coated with Diamond like Carbon of Nano-scale Thickness towards the Applications in Statistical Features of Fluid MechanicsBy Subhadeep Mukhopadhyay
Abstract: In this experimental work, polymethylmethacrylate (PMMA) is the chosen polymer as device material to fabricate the microfluidic devices. PMMA is optically transparent polymer which is a facility to record the microfluidic flow of any dyed working liquid inside the fabricated microchannels. Two individual microfluidic devices are fabricated by lithographic techniques. Dyed water is selected and prepared as working liquid. Leakage-free surface-driven capillary flow of dyed water is recorded corresponding to …

Short Report on Polymer Based Automated Fluid Machines for Applications in MicrofluidicsBy Subhadeep Mukhopadhyay
Abstract: In this experimental work, a couple of gradual expansion microchannels are fabricated by polymethylmethacrylate (PMMA) using the maskless lithography, hot embossing lithography and direct bonding technique. Dyed ethylene glycol and dyed water are the prepared working liquids. The CMOS camera catching 25 frames per second with a corresponding time-scale resolution of 0.04 second is used to record each surface-driven microfluidic flow of dyed ethylene glycol and dyed water in the …

Report on Microfluidic Flow of Dyed Working Liquids inside the Polymeric DevicesBy Subhadeep Mukhopadhyay
Abstract: In this experimental work, a single SU-8 based glass microfluidic device is engineered by the maskless lithography and indirect bonding technique. Also, total nine individual polymethylmethacrylate (PMMA) based microfluidic devices are fabricated by maskless lithography, hot embossing lithography, and direct bonding technique. Dyed ethylene glycol, dyed ethanol, and dyed aqueous isopropyl alcohol (50% water, 50% IPA) are prepared and used as working liquids to record each surface-driven microfluidic flow. The …
