I have been working on using the membranes to trap blood cells so that I can take force measurements with the AFM. It is impossible to perform AFM on blood cells resting on a coverslip because the water displaced by the tip on the approach pushes them away, so I am trying to use a…
Air permeability (w341, 342, 344, 345) Burst Pressures (w341, 342)
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 die size). The TEOS chips allows water and media with serum to much more easily…
Here are images of actin filaments on Formvar coated 200 mesh nickel grid. Actin filaments were polymerized exactly as before. TEM sample preparation procedure is: 1. add actin solution on Formvar grid and wait 90 sec 2. remove liquid, add same volume of 2% UA and wait 90 sec 3. remove liquid and load on…
Looking back at production over the last year, I noticed that our porosity has dropped considerably. Now that we have a good handle on controlling pinhole density, it is time to focus on controlling morphology again. Below are two examples of a 15 nm and 30 nm pnc-Si film produced this month and one year…
I’ve been trying for some time to make chips that can dynamically change their surface charge. To this end I’ve made the following NFT chips, which have 12 nm of silver coated in 10 nm alumina: Note the Aluminum foil coating the insides of the gel box. The silver layer is either photoactive or…

Still no details on the membranes. I’m impressed that they get to go to Capital Hill, but I don’t see where their breakthrough is.
