Fabrication of PDMS Microfluidic via Room Temperature Rapid Prototyping Process

摘要

An in-expensive way of fabricating PDMS microfluidic using room temperature curing process is presented; the device can be used for both laboratory and commercial scale. It was designed using AutoCAD for master mold preparation and subsequently created with SU8 for rapid prototyping process; the micro mixer and the whole mixer were fabricated in less than without using costly fabrication steps. The device profiles were observed for structural integrity and evaluation by dropping two food coloring dyes through the two inlets and collecting the sample at outlet. Flow rate and mixing efficiency were quantitatively measured by analyzing the recorded flow profiles and values of the image collected from the high powered microscope at inlet and outlet locations is fully obtained and will be presented in our next publication.
