Crystal Growth inside Nanopores

I was not entirely satisfied with the amount of data that I received from my last burst pressure wafer, so I processed another wafer. This wafer had some yield loss initially, as well as window sizes that were slightly smaller than expected (by about 50 microns). We expect the mechanical strength of the windows to…

So, I have been working with a 4-probe TEER measurement system to record the changes in endothelial permeability during neutrophil extravasation and other biochemical assays such as thrombin treatment and TNF stimulation. 4-probe systems are sensitive because they don’t suffer from the contact impedances and measure only the potential drop across the sample under consideration. See…

Lately, Anant and I have been doing our discoloration experiments under purposely harsh conditions so we don’t have to wait for multiple days for experiments to finish. We have lots of evidence that the 3D format slows down discoloration (post1, post2, post3). This experiment was to test how long samples will last in 3D format…

We have successfully plated adipose derived stem cells (ADSC) on microporous silicon nitride (SiN) membranes. Cells plated on nanoporous SiN appeared fine at time of seeding, but membranes were broken at 2 hours – possibly due to media washing or cell spreading/contracting. Josh Miller made new Microporous and Nanoporous Nitride liftoff membranes. These membranes were…
