Surface-Driven Capillary Flow on Microchannel Surface Coated with Diamond like Carbon of Nano-scale Thickness towards the Applications in Statistical Features of Fluid Mechanics
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 …

Experimental Studies to Record the Lithographically Fabricated Microstructures by Surface Profilometry and Scanning Electron Microscopy for Microfluidic Laboratory-on-a-Chip Systems
Abstract: In this research paper, the poly(methyl methacrylate) (PMMA) microfluidic laboratory-on-a-chip system is fabricated in the cleanroom laboratory by maskless lithography, hot embossing lithography and direct bonding technique. The microstructures of the lab-on-a-chip system are measured by surface stylus profilometer. Also, the images of microstructures of lab-on-a-chip system are captured by using scanning electron microscopy (SEM). This fabricated lab-on-a-chip system is useful in bioengineering applications.
