Effect of Surface Free Energy on the Surface-Driven Capillary Flow in SU-8 based Glass Microfluidic Devices
Abstract: Surface-driven capillary flow of dyed water is recorded in the SU8 based glass microfluidic devices fabricated by the standard cleanroom processes. The effect of surface wettability on the surface-driven capillary flow is studied in the individual SU8 based microfluidic devices of glass bottom wall and polyimide bottom wall. The surface-driven capillary flow is faster on the glass bottom wall surface due to the higher polar component of solid surface free …

Optimisation of the Experimental Methods for the Fabrication of Polymer Microstructures and Polymer Microfluidic Devices for Bioengineering Applications
Abstract: In this research paper, total 2278 individual polymer microstructures have been fabricated, measured and analyzed. Also, in this research paper, total 216 individual polymer microfluidic devices have been fabricated by the maskless lithography, hot embossing lithography, direct bonding technique, and indirect bonding technique, to record and analyze the surface-driven (passive) capillary flow individually in each microfluidic device. Total three individual polymers as SU8, polymethylmethacrylate (PMMA), and polyimide have been used …

Effect of Surface Wettability on the Surface-Driven Capillary Flow in SU-8 Microchannels
Abstract: AbstractSU-8 microfluidic devices have been fabricated by the maskless lithography. Passive capillary flow is suitable to manipulate liquid in the lab-on-a-chip systems. The surface-driven capillary flow of dyed water in each microfluidic device has been recorded and analysed. The measured static water contact angles are 72.6°and 81.2° on the hydrogenated amorphous carbon (a-C:H) deposited flat surface and Si-a:C:H deposited flat surface respectively. Either, a-C:H or Si-a:C:H has been deposited on …
