Experimental Study on the Surface-Driven Capillary Flow of Aqueous Microparticle Suspensions in the Straight PMMA Microchannels

Subhadeep Mukhopadhyay

Abstract


The straight polymethylmethacrylate (PMMA) microchannels are fabricated by the maskless lithography, hot embossing lithography and direct bonding technique. Total 120 individual PMMA microfluidic devices are fabricated by author’s own hands-on completely. Total 120 individual audio video interleave files as ‘FileName.avi’ are recorded and analyzed by author. The surface-driven capillary flow of different aqueous microparticle suspensions are recorded in these straight PMMA microchannels. The effects of channel aspect ratio, effective viscosity and surface wettability on the surface-driven capillary flow of different aqueous microparticle suspensions are analyzed.
