Microfluidics Research

About the Group

The Microfluidics Research Group is a new initiative at Memorial University. The group is highly interdisciplinary and is devoted to the development of new microfluidic based technologies. These applications include developing analytical tests, micro-cooling technology, and BioMEMS. Under the direction of individual group members, students can fabricate, analyse and test microfluidic devices for a wide array of applications such as microelectronics cooling and lab on chip.
