Polycarbonate track-etch membrane with high pore length-to-diameter aspect ratio

Using Mike B.’s MATLAB script, I was able to generate some histograms and stats for wafer 187, 310, 319 and 320. I excluded the “small pore background”, as I do not believe these features go all the way through the membrane. wafer 187 wafer 310 wafer 319 wafer 320 The reason why I did not…

We borrowed a method first published by Jahn et alii about 7 years ago, in which lipid dissolved in ethanol are streamed through a central channel and compressed by 2 streams of  buffer (we used PBS).  This hydrodynamic focusing results in the generation of liposomes at the interface of the miscible liquids.  This results in…

Here are the Vascular Interviews in comma separated value form if you want to download them. Here is what I learned or had reinforced. An arteriovenous fistula (AVF) is the preferred method for creating an easily cannulated access point to large volumetric blood flow for hemodialysis. Normally the distal end of an artery in the arm (e.g. brachial or…

As a step to identifying the particles that I am capturing in my systems, I am attempting to do an immunogold labeling with a CD 63 primary antibody and a 10 nm gold conjugated secondary. It is possible to run this analysis in an SEM, but the best confirmation method is using a TEM and…

Following up on our previous work with SiN-NP with varied RIE times, Sarah and I measured permeability and permeance using a new measuring system better suited to the higher permeance and permeability we expect with the larger pores and higher porosity. Using the pressure regulator pictured above, we can set pressures of 3 psi and above…
