Experimental Demonstration on Polymer based Microfluidics

Subhadeep Mukhopadhyay

Abstract


In this experimental work, a single polymer based gradual expansion microchannel is designed. This microchannel is fabricated by the maskless lithography, hot embossing lithography and direct bonding technique inside the cleanroom laboratory. Dyed water is the prepared working liquid in this work. The surface-driven (passive) microfluidic flow of dyed water is recorded in the fabricated device using a CMOS camera catching 25 frames per second with a corresponding time-scale resolution of 0.04 second. Leakage-free microfluidic flow of dyed water is recorded due to proper direct bonding technique. This experimental work may be useful for bioengineering applications in future.
