Short Review on the Materials for Microfluidics with the Experiments to Record the Surface-Driven Capillary Flow of Dyed Water in Fabricated Microfluidic Device for Bioengineering Applications

In this review, dominant features of suitable materials for the fabrication of microfluidic devices are briefly mentioned. Surface modification techniques are useful to vary the flow-speed in microfluidic devices. Surface modification techniques are dependent on the choice of device materials. In this present paper, a single polymeric microfluidic device as sudden expansion microchannel is fabricated by author using maskless lithography, hot embossing lithography and direct bonding technique. Also, the surface-driven capillary flow of dyed water is recorded corresponding to the fabricated microfluidic device. Effects of channel aspect ratio and channel volume on surface-driven microfluidic flow are described. This work may be suitable for bioengineering applications related to the research-areas of microfluidics in future.
