Nano-Scale Coating to Demonstrate the Capillary Motion of Dyed Water in a Single PMMA Microfluidic Device towards the Probable Fabrication of nanofluidic Engine-on-a-Chip

Subhadeep Mukhopadhyay

Abstract

A single microfluidic device is fabricated by polymethylmethacrylate (PMMA) using the maskless lithography, hot embossing lithography, nano-coating of diamond-like carbon (DLC), and direct bonding technique. A CMOS camera catching 25 frames per second with a corresponding time-scale resolution of 0.04 second is used to record the surface-driven microfluidic flow of dyed water. A comparison is made between the experimental results and analytical solution to determine the diffusion coefficient in this work. This experimental work may be helpful to fabricate the nanofluidic device in future to record and analyse the nanofluidic flow phenomena. Also, this experimental work may be suitable to fabricate the nanofluidic engine-on-a-chip in future.

Keywords
