Efficient micromixing is required for fast reaction and improved mixing performance for DNA extraction in microfluidic devices. This study outlines a simple, low cost approach for prototyping design and fabrication of PDMS microfluidics micromixers for DNA extraction. The design is plotted using AutoCAD software and the master template is fabricated using a negative photoresist, SU-8, on a microscopic...
Lab on a chip (LoC) is a device which integrates the function of bio-chemical laboratory into a single chip. The microfluid which flows within the chip is analyzed biochemically for certain purposes, e.g. for biomedical or environmental analysis. LoC is commonly found in a form of chip with thin glass, silicon, or PDMS. In this paper, we report our work on fabrication of all-plastic flexible microfluidic...
A rapid prototyping method was developed to integrate a microfluidic plasma separation device over a Si based radiation detector. KMPR photoresist was used to produce high pressure resistant channels sealed by a glass cover. Two methods were investigated to make access holes in the cover: laser micromachining and a simplified glass wet etching process. The lab-on-chip concept where a plasma separation...
