Abstract
In this short report, a brief review on surface-driven microfluidic flow is provided. Also, the maskless lithography and indirect bonding technique are used to fabricate a single SU-8 based glass microfluidic device. Dyed ethylene glycol is prepared as working liquid to test the fabricated device. The surface-driven microfluidic flow of dyed ethylene glycol is recorded by a CMOS camera catching 25 frames per second with a corresponding time-scale resolution of 0.04 second. This short report may be useful in future to control the working liquid inside the microfluidic lab-on-a-chip system. Liquid-microflow is slower at higher surface-area to volume ratio inside the microchannel. The surface-to-volume ratio is generally very high inside any Nanochannel. Therefore, the Liquid-flow may be stopped before the Nanochannel. Hence, only gas-Nanoflow may happen inside the Nanochannel producing the subject of Nanofluidics. Hence, this short report may be useful in future to control the working gas inside the nanofluidic lab-on-a-chip system.
