After a false start with non-microporous TEOS chips, I quickly did an image comparison with truly porous chips using polystyrene beads. The TEOS and Silicon Nitride chips were both fabricated in the single-well CytoVu format (single 2 mm window, 5.4mm…

Pressurized Gold Separations – Part 3
Dan Mendelson performed gold separations using wafer 255 and has shown that this wafer has a cutoff for gold near 25 nm. Below I have plotted the data of filtrate gold concentration as a function of the feed concentration for…
Pressurized Gold Separations
Motiviation and Background: Nakul and I have been performing a lot of DNA filtration and attempted DNA shearing experiments. We found that large DNA fragments (>1000 and >2000 bp) pass through ~30-40 nm max pore size membranes when pressurized to…
