12 February 2009 Lab Meeting Agenda

  • Status: compressed air and vacuum?

† Announcements

  • Sonali out for a week.
  • New senior project team.
  • MicroTAS abstracts.

† Flu R01

  • Modified Schedule this week.
  • Plaque Assay.
  • Alex needs to be trained to make SU molds. Trained to make the monoliths (by Hussam By 1/15/09)--we're about to start the training--.

† SEPSIS Project

  • Sonali done with draft.
  • Hussam working on Lambda phage data.
  • 1 ml methanol wash seems to be taking care of the issue.

†RNA project

  • More formal report to Jeff from Cathie.
  • Do cDNA prep. Spec, gels, send to Jeff B. Shipping?


  • Mark- Control circuit - done, need to be tested.
  • Evap quantification experiments.(JD, JZ)

- Petridish culture after running evaporation w/o dye in hydrophobic treated channel
- ; Viability low as < 20%, Huge variation in results
- try running the experiment first, then running the live/dead dye through second. Bold text
- ; Live/dead assay kills 90% bacteria proven by test.
- Direct measurement with engineered SERS substrate.

  • Test with engineered SERS substrates

- 500umx500umx50um dimension informed to Luca and Bjoern
- Need to schedule when they are ready

  • Substrates (JZ)

- new set made, in glove box: the 1st 3 on the DOE. SEM and SERS available.
- hypothesis: drying controls clustering, reduction controls size?

  • DOE for the experiment.

- need to add humidity as it changes even in the glove box - this is no longer an issue, asked Ranjith and now can adjust humidity to constant
- set II done varying drying time and fast reduction time. SEM and SERS available.

  • Colloid experiment. inconclusive. Look at SEMs

- difficulty in locating the bacteria
- needs much higher particle/bacteria ratio
- experiments outside the channel first?

  • Look at the unused substrates in SEM one week old or more.

† Valve Array/Valve building (FJ)

  • Teddy on track.
  • Valve tested

† Fraunhofer: LOAC

  • Paper drafting!

† Biointerfaces group

  • Final experiments in process? Need one more experiment next week

† CIMIT- Colson Grant

  • IRB still in revision.


  • flu cDNA was successfully amplified on chip,one band show up in gel. experiment has been repeated for three time.
  • working on the surface coating of zeonex, looking for an effective way to verify the PEG layer
  • tried contact angle, device broken
  • SEM did not give out a lot of information
  • scheduling XPS
  • DNA chain model is being made (5 beads model tested).


  • Cathie submitted One pager Whitepaper. Waiting for response.


  • Large volume filling and valve tested.
  • Design issue - whole integration or assemble parts (SPE & HDA chamber)

† Senior project

  • Megan 1)did some preliminary bonding with Zeonex and teflon film. 2) emailed off the Mask Design to FineLine

† F31: Cochlea

  • Pre-gent vs. Post-gent-- most interesting data: decorin upregulation, fibronectin gradient
  • Six antibodies. Verifying 4 with protein pre- and co-incubation with antibody. Could not find the other two proteins
  • Finalized poster and printing for ARO
  • ARO is next week

† Silica Optimization (Lambda):

  • Overview to look at the data collectively [1]
  • Next E. coli.
  • try another color DNA dye. Pico green works ok
