Breaking the barriers to manufacture thermoplastic microfluidics!

Thermoplastics, such as Cyclin Olefin Copolymer, are used in commercial applications of microfluidics because they are biocompatible, have good material properties such as optical clarity, low fluorescence, high toughness and are cheap to mass produce. However, there are challenges for academic labs to make thermoplastic microfluidics devices. Fabricating molds for thermoplastics is expensive and other process steps, such as sealing the chip and interfacing the chip to the lab are difficult. In a recent publication, the Fraden lab described an inexpensive method for rapid prototyping of thermoplastic microfluidics suitable for academic labs for applications such as x-ray diffraction of protein crystals produced on the same chip in which they were crystallized, or for labs seeking to manufacture a thermoplastic prototype of a microfluidic device in order to demonstrate the potential for mass production. This process will facilitate the transfer of University developed microfluidics to commercialization.
