MICROFLUIDICS FOR CHEMICAL ANALYSIS Sandia National Laboratories has a major program in developing and using microfluidics for chemical analysis. We believe that these capabilities could contribute significantly to DARPA's BAA 97-39 on microfluidic analysis and associated design tools and, as a Federally Funded Research and Development Center (FFRDC), we would like to offer these capabilities to any and all potential partners in responding to that BAA. Specific capabilities include novel methods for pumping and valving of fluids over a greater range of fluid properties and with greater control than current approaches; research and diagnostic techniques that include direct, real-time imaging of the flow to optimize fluidic design and flow parameters; continuum and monte-carlo fluid modeling for modeling a variety of electric field driven flows; integrated micro-optics for ultra-sensitive optical detection in conjunction with arrays of microfluidic channels; and on-going work in the use of arrays of a large number of parallel chromatographic channels for high specificity detection with extremely low false alarm rates. Interested parties should contact Dr. John Vitko, Jr. MS 9056, Sandia National Laboratories, P.O. Box 969, Livermore, CA 94551-0969 (FAX: 510-294-2276; e-mail: john_vitko @sandia.gov). Deadline for response to the BAA is September 19th. In order to respond to the BAA in a timely and coordinated manner, we would like to have interested parties contact Sandia by September 10, 1997. Please note that as an FFRDC we are not able to enter into any exclusive collaborations in response to this BAA, but instead must offer the same capabilities to any potential partner interested in teaming.
