As we were conducting our experiments on dimpled Sylgard substrates we knew that another micro-topography that we wanted to investigate was micro-pillars. In like manner to the dimples, a post microtopography should provide some sort of surface for the cells to “grab onto” and spread as they would on any ECM in vivo. These…

Combining Pores Affects the PoreImageProcessor, but Not Enough to Throw Permeability Off 2x
In Tuesday’s NRG, we wondered if the fact that some of Josh’s pores overlap could throw the PoreImageProcessor off enough to explain a 2x discrepancy between our theoretical hydraulic permeability and our experimental permeability (the experimental was lower). From this picture: I took the following close up: If we assumer that each of the sub-pores has a radius of…
Blood and PBS in large Lift-off device.
I attempted to clear the large format lift-off devices (from Josh). I was unable to clear, in a reasonable amount of time (< 2 hours) by pumping IPA. So I switched to PBS then Blood and blue-dyed PBS (dye is estimated to be between 10 nm and 500 nm, obviously the amount of dye near…
1085 MgF2 TEM Stereography Reconstruction
I’ve received some of the very first MgF2 material that I produced way back when and shipped off to Nottingham. These chips were produced from NPN wafer 1085 (5-slots). There are a few membranes still remaining, but mostly the chips are in tatters. Tomogram Reconstruction Weighted Back Projection (quick and dirty) We…
