Viscoelastic material PolyDiMethylSiloxane (PDMS) is one of emerging candidates for the fabrication of Microfluidic Chip (MC) in micro scale for a wide range of applications in biological and medical research. So, PDMS is used as one of the most frequent materials for the formation of inexpensive MC with different microfluidic channels due to its excellent properties of optical transparency, easy and swift fabrication process, chemical inertness and low shrinkage rate with the replication of mold into micro-scale environment. Moreover, CAD designed 3D printed structure to fabricate replica mold of MC using PDMS eliminated the necessity of using expensive clean room facilities with time consuming fact. In this paper, we measured the interactions of two pH buffer solutions through our designed micro flow channels with the captured THz images within Terahertz Chemical Microscope system.
