Short Review on Passive Capillary Flow in Microfluidics with an Experimental Demonstration about the SU-8 based Microfluidic Device

Subhadeep Mukhopadhyay

Abstract


In this experimental work, a single SU-8 based glass microfluidic device is fabricated by maskless lithography and indirect bonding technique. The surface-driven microfluidic flow of dyed water is recorded in the fabricated SU-8 device. Negative photoresist SU-8 is an efficient polymer to fabricate the microfluidic devices. A brief review on surface-driven passive microfluidic flow is provided in this short experimental report towards the applications in microfluidic lab-on-a-chip systems. This short experimental report may be useful for blood filtration in SU-8 based lab-on-a-chip systems, for example, structurally modified microchannel bend. 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. Also, this work may be useful to fabricate the fluidic microelectromechanical systems (MEMS).
