Silicon Prairie International Microfluidics Symposium

November 1, 2014

West Campus

University of Kansas, Lawrence, KS

Over 60 people gathered at KU for the Silicon Prairie International Microfluidics Symposium (SPIMS), an afternoon of outstanding short talks by eight experts in the field of microfluidics. SPIMS featured talks by:


Front row, L-R: Sabeth Verpoorte, Prajna Dhar, Cindy Berrie, José Alberto Fracassi da Silva
Back row, L-R: Dulan Gunasekara, Susan Lunte (Director of Adams Institute), Wendell K. T. Coltro, Mei He, Christopher Culbertson

Participants had an opportunity not only to hear about some of the latest research in microfluidics, but also to present their own research at what was an extremely interactive poster session with 18 posters given.  During the poster session, attendees were also provided tours of the Microfabrication and Microfluidics Core facilities in the Multidisciplinary Research Building on KU’s west campus.

SPIMS was a great success, thanks to participants who traveled from various parts of Kansas and North Carolina (not to mention Brazil, The Netherlands and Thailand!).

"Integrated Microfluidic Systems for Forensic DNA Analysis"
In 2006, we demonstrated that microfluidic technology could provide a ‘lab-on-a-chip’ solution for real-world genetic analysis. Sample-in/answer-out functionality was shown for the detection of bacteria in mouse blood and in a human nasal swab, with a sub-30 minute analytical time for DNA extraction, amplification, electrophoretic separation and detection. We extrapolated these technology developments to the analysis of short tandem repeats (STR) in human DNA; these clinically-insignificant (presumably) tetranucleotide sequences function effectively for statistically-relevant matching in human identification. Our efforts led to the development of a commercializable system designed for implementation in crime labs for STR profiling convicted felons or, in some states, profiling arrestees in booking stations. An intricate but functional microfluidic architecture allowed sample-to-profile to be achieved from a cheek swab in less than 80 minutes, using nanoliter flow control, infrared thermocycling and rapid electrophoretic separation of DNA with 5-color fluorescence detection. We have since demonstrated the fabrication of hybrid microdevices composed of inexpensive polymeric materials, many of these commercial-off-the-shelf. We have designed, built and functionalized fully-integrated DNA analysis chemistry/microfluidics on a rotationally-driven system the size of a compact disc. With this system, DNA can be extracted from a swab, PCR amplified to generate an abundance of DNA fragments of the STR loci, followed by resolution of those fragments in a separation in a 4 cm Leff channel that is complete in <300 sec with a 2-base resolution. The processes that allow for swab in–profile out microfluidics are carried out on an instrument that can be carried in one hand and weighs ~14 lbs, ultimately allowing for facile rapid human identification/screening in the field.
