† 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

• 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!
  

† COBRA

• 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
