In this post I take a look at the flux of molecules through the 1-D membrane simulations.  I will then use this flux to compare to systems lacking a membrane. First off, how to find the flux.  Inside the membrane, the Flux = -Dm dc/dx.  Unfortunately this is extremely hard to calculate because of the…

Hi all, this is Henry. Leeanna Hyacinth, an undergraduate student from the McNair program, has recently completed a joint project between the Waugh, Palis, and McGrath Lab to create a bioreactor to amplify the number of mature red blood cells. Background: The Palis lab has discovered a method to amplify erythroid precursor cells (from 1…

The unwashed membrane has a definite “film” over it which makes the pores look textured.  The MeOH & H2O seems to clear the pores up, but there are some places where there is remaining PVP that sticks to the inside walls of the pore.

I’ve suspected that the barrier function of endothelial cells might be surface-dependent (that is, cells grown on the pnc-Si side vs. cells grown on the well side).  I hypothesized that the interface between membrane and well walls would alter the continuity of the endothelial monolayer when cells are grown on the well wide.  To test…

Here are the conversion ratios for the URMC TEM images (so we’re all using the same standard): 30kx – 0.39 px/nm50kx – 0.67 px/nm150kx – 2.2 px/nm300kx – 4.5 px/nm These numbers should be used for wafers 187, 189, and > 310. Unlike the RC TEM conversions, these numbers seem to be consistent between the…

This an extremely important topic that has come up multiple times in discussions within NRG as well as during my qualifying exam. The question is: are gold nanoparticles a good model for exosomes? The reason that this question comes up is because exosomes are biological material and as such they have some vastly different properties…
