2011 Workshop on Capillary-based Microfluidics for Bioanalysis

The University of Washington held a Microfluidics 2.0 workshop Oct. 1–2, 2011 in Seattle, WA. Topics ranged from a practical guide to flow in porous media, to applications of Microfluidics 2.0, to the challenges of device development for point-of-care settings. The one day workshop consisted of a seminar series, while the two-day workshop extended to include hands-on tutorials on the second day.

The agenda for this workshop can be found below.  For copies of the presentations, along with photos from the event, please click here.  

Speakers for the 2011 workshop included: Patrick Beattie, Diagnostics for All; Elain Fu, UW Bioengineering; Barry Lutz, UW Bioengineering; Michael Mansfield, Millipore; Andres Martinez, Cal Poly; Roger Peck, PATH; Scott Phillips, Penn State; Bernhard Weigl, PATH; George Whitesides, Harvard; and Paul Yager, UW Bioengineering.
