Short Report on the Polymer based Microfluidic Device Fabricated by Lithographic Techniques

Subhadeep Mukhopadhyay

Abstract

In this experimental work, a single microfluidic device is fabricated by maskless lithography, hot embossing lithography and direct bonding technique inside the cleanroom laboratory. Microchannel bend is the selected design to fabricate the microfluidic device. Dyed ethanol is selected and prepared as working liquid. The surface-driven capillary flow of dyed ethanol is recorded in the fabricated microchannel bend using a CMOS camera inside the materials-science laboratory. Effect of centrifugal force on surface-driven capillary flow is studied in the fabricated microchannel bend. This work may be suitable in the applications related to applied chemistry. Keywords: PMMA; Microchannel bend; Hot embossing; Direct bonding; Ethanol
