Using wafer 302 I set up 2 20nm and 2 50nm gold diffusion experiments. After 24 hrs I removed the retentate and filtrate and looked for the gold using the Malvern Zetasizer. We can’t perform the diffusion with both 20nm and 50nm gold because the Zetasizer cannot differentiate between the two sizes. r value Sample…

This post presents the data from all of my TEER experiments of BBB co-cultures, with bEnd3 endothelial cells on the bottom and NG101815 glia on the top of PET and pnc-Si transwells.  For all experiments, I used 50000 cells/cm2 as the seeding density.  I always had 3 samples – bEnd3 alone, NG10815 alone and the…

The following data is from analysis of Wafer #1059, consisting of 30nm pnc-Si with 7% porosity and an average pore diameter of 28nm. Square window sizes with sides lengths of 0.1mm, 0.3mm, 0.5mm, 0.7mm, and 0.9mm were tested. For 1.1mm x 1.1mm windows, burst pressures could not be determined, as these windows did not etch…
