There is strong evidence that the recent pinhole breakout is due to copper contamination in our process. I have attached two image – An SEM showing a cuprous creature eating one of our membranes and an EDX (Energy Dispersive X-ray?) spectra identifying it as a copper-rich silicide. This would also explain Dave’s TEM image of…

Here is the paper I reviewed at the NRG meeting on 06/19. Utah Group Micro BBB Device I’ve also included my presentation: BBB Device Presentation This week I’m working on designing the basal and apical chambers, considering the necessary shear stresses.

Production this week focused on varying the RTP temperature of membranes deposited under identical conditions. wafer 316 – 800 C RTP (120 s) (0,-5) @ 50 kx Material still appears to be amorphous. Wrinkled at edges. wafer 318 – 900 C RTP (120 s) (0, 0) @ 50kx (-5, 0) @ 50kx A few, very…

All of my recent posts on VEGF, VEGFR2 and NF-H imunofluorescence have included data from cells grown on coverslips only.  This was my first attempt to try to do immunofluorescence staining on intact pnc-Si transwells and then pop the chips out of the transwell plastic in order to image at 100X.  Since VEGF is involved…

In response to last meeting: We tested more controls to help support our idea that the ADSC are migrating toward HUVEC network and prematurely breaking them down. We used a 100% Geltrex coated cytovu gasket to test if ADSC are attracted to something in the Geltrex causing them to migrate. The ADSC did not migrate…

JP handed me a stack of wafers today, and I went over to the Krauss Lab and with the help of Jack Calcines got some AFM images.  I didn’t have much time to play with, so I tried to get the most data I could quickly.  I think we’ll have to do a more exhaustive…
