Capillary Tubing and Adapter

I was not entirely satisfied with the amount of data that I received from my last burst pressure wafer, so I processed another wafer. This wafer had some yield loss initially, as well as window sizes that were slightly smaller than expected (by about 50 microns). We expect the mechanical strength of the windows to…

I spent some time testing the various steps of the transfer and wetting process to see if I could find the cause of membrane delamination that I saw earlier. The result seems to be that time is the main culprit. Here is the membrane just after transfer (dry between the membranes initially, steam after transfer…

Karl and I attempted once again to filter particles with the SiN-NP 5 slot SEPCON chips.  (wafer # 1019, 27% porosity, avg. pore dia. – 54 nm in the center, 30%, 61 nm at the perimeter, histograms below)   We started trying to first pass 20 nm red fluorospheres, then block 100 nm yellow fluorospheres,…

[latexpage] Hello Everyone, So i decided to do some calculations on our 2 different sets of experiments (Track Etched and NPN) and compare the applied and the required force of them, in addition to making sure that we are applying enough force on the particles to keep them captured. The experiment conditions for both TE…

We previously explored cell migration and cell-substrate interactions in the form of altered f-actin polymerization, focal adhesion formation, and fibronectin fibrillogenesis on the discontinuous substrates (porous membranes and non-fouling PEG islands). Here, we were curious about mechano-sensing on these substrates. We first investigated the f-actin polymerization and focal adhesion formation of Adipose-derived stem cells (ADSCs)…
