Rat Dialysis Device Animations
Here’s a few sketchup animations I made for Dean’s device, based on his PPG presentation last week:

Calcein vs. CMFDA staining
The other (see below) just-to-be-sure experiment I performed this week was to compare staining between 2 different live cell dyes. I typically use calcein AM to stain live cells green. This is a membrane-permeant dye which, once inside cells, is hydrolyzed by intracellular esterases to make it fluoresce green. Another very common live cell stain…

Reversible nano-confinement with a post-filter
My last experiment did not go as planned, but the results are very interesting nevertheless, and might provide another interesting application for these tw0-membrane systems that we had not yet considered. The start of the experiment went as planned: painted PDMS on the chip, used additional PDMS to glue the gasket to the PDMS layer,…
Annealing free-standing membranes
I first reported the crystallization of free-standing amorphous silicon membranes in this post in January. The last experiment was done inside the susceptor (top and bottom piece). This week, I annealed a set of amorphous 15 nm and 30 nm with the susceptor top off. This allowed for the direct heating of the films. One…
Nanoporous Wallpaper
In my recent tenting posts, the membrane has shown that it can deform and wrap around edges. I wanted to follow up on this phenomenon and see if we could get a contiguous sheet of membrane around a PDMS edge (not completely sharp). If we can get some membranes around a ~90 sidewall, we could have…
