Alec’s Proposal Exam Documents

Below are images from two samples that were annealed at 950 C and 1050 C post-EDP etch.  The lower temp anneal produced a membrane with many features that do not seem to penetrate the nc-Si.  There were a few (couple in each field) smaller pores ~ 10 nm in the outer samples.  This supports Jess…

In response to last meeting: We tested more controls to help support our idea that the ADSC are migrating toward HUVEC network and prematurely breaking them down. We used a 100% Geltrex coated cytovu gasket to test if ADSC are attracted to something in the Geltrex causing them to migrate. The ADSC did not migrate…

The week before last, I finally switched back to my exosome experiments with some hope of repeating my January successes with my new clampable format and two pump system. After failing for several hours (and breaking 7 membranes), I was finally able to get the system to work and get a sample for SEM. (A…

In Nottingham this summer, I attempted to use a Makerbot2 printer to create culture devices for SEPCON chips. I had varying degrees of success, but I was not able to get a good seal between the PLA and gaskets using only machined grooves. This would have limited our ability to do TEER and other 2-chamber…

I don’t think I ever posted it on the blog, but two years ago I discovered something neat. At the time, I was trying to make my nanofluidic transistor, and I was reading Marina’s thesis. She tried to improve the efficiency of our EO pumps by putting silver films directly on the front and back…

In the past couple of weeks I’ve tried a few more molecules to flesh out the experimental verification of the separations model.  This is a quick update of the results.  In the following figure, the blue line is the predicted sieving curve, the green line sieving given a no membrane/free diffusion situation, and the blue…
