† Other Announcements
 * Cathie Bring IBM laptop and drive from home
 * No meeting 9/1.
 * Register for CIMIT conference if you want. Irene can reimburse.
 * Register for IMECE in Boston
 * Register for MRS Boston if you want to.

† Flu R01
 * Meeting set F afternoon (8/29)
 * Planning plaque assay - protocol decided

† SEPSIS Project/Chip Bonding Issues † COBRA
 * Check if Anlee can do backscatter electrons on new SEM
 * EF experiments results later today
 * Chips did not bond - that were made last weekend.
 * Controlled cooling with air plasma bond okay with Zeonor plaque.
 * Topas COC resin may be better to try. Try and buy some. (this is what the plaques are made of) The COC might shrink less. (co-polymer).
 * Jaephil will help Sonali get some new material for the sepsis chips.
 * Wash is acetone then methanol sonication + DI water sonication. SEE UPDATED PROTOCOL!
 * Jaephil and Mark making humidity and flowrate control box (temp too) for the concentration system.
 * IEEE abstract submitted on 8/24.
 * IBC for our lab STILL pending - Alexis will give us the requested revisions
 * Cathie will submit this week (8/29)
 * Tests on chips with covers underway
 * Jane is investigating the multilayer design

† Valve Array
 * Cathie contact Sumita Pennarthur at UCSB about her valves
 * Waiting for fixture from Melissa
 * Mark's Part is complete at this point
 * Basic software in place

† Fraunhofer: LOAC
 * Still troubleshooting

† Biointerfaces group
 * Brett and Mincheol tried the SU8 process.
 * Hussam made 6.5 microns SU8 - Using the Hard contact method
 * Hussam made the PDMS part. Correct part, but overexposed. The thickness is too thin
 * Mincheol will try the device as we have it
 * Hussam will make 20 micron high with 1 micron space this week/or Brett
 * SU8 thickness is important step in this process. So, ALIQUOT SU8 when it arrives.
 * Solvent evaporation from the SU8 can be a real problem.
 * Use the same spinner every time for this project.
 * Wafer cleaning should be the same every time, too
 * Hussam, Brett and MinCheol are going to make a protocol for this process
 * AZP 4620 from Clariant. Hussam will try this photoresist (positive)

† CIMIT
 * Meet with Sepsis Nurse Tuesday.
 * QQ submitted abstract.
 * Jane submited.

† PCR
 * QQ Model has 30 cycles. MinCheol will try the model. Need to upgrade the Star-CD program. Dan Kamalic has to do this.
 * Emailed Dan today.
 * QQ passed qual!! yeah!!!
 * Old heaters worked 20+ times, but then are not homogenous across chip.
 * Waiting for new heaters to try again. Other brand was not good. Will use copper in the meantime for temp control.
 * PUMP problem. Speed control at low flow rates is not stable.
 * What are the specs on Wong's pump?
 * What are the specs on our pumps?
 * Can KDS calibrate or fix it?
 * We need at least one more pump that does multiple channels. Mincheol will check the specs?
 * What requirements does everyone have for their "IDEAL" pump.

† RCA
 * STILL Working on a test chip to examine mat'ls compatibility
 * 50 microliter test chip made/ may be and issue getting the stuff out. Especially after the wash.
 * RCA meeting with Heiko, Jaephil, Sonali this week.
 * Whitepaper composition.

† Senior project
 * Megan still gone.
 * New students will be recruited.

† F31: Cochlea
 * Nathan in Oregon

† Silica Optimization (Lambda):
 * Ongoing

Hussam's Update
