From SiMPore’s Basecamp thread … 
These are the nanopore characteristics. So between 14% and 20% porosity across the wafer and between 43 nm and 50 nm average pore size.
So a little under-sized. I hope T-Cells and Monocytes can get through!

The overall goal was to see is if it was possible to create a reliable low resolution mask that can be used for crosslinking PEG structures using a laser printer and transparencies sheets. With these masks, I explored to see if there is an effect on the PEG structures when dimensions such as the spacings…
With the help of Henry and Greg, the Fisher team has been busy learning the basics. John and Ryan have learned some PDMS microfluidics-making and will have their first chips ready on Tuesday. We have also been playing with the silhouette printer, studying our options for producing some simple devices. Finally, we produced some chip designs to…
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…
Hello Everyone, Following my experiments with Track Etched Membranes: So we came up with this idea to perform SEM imaging. Following are the images that i took for my experiment with 100 nm beads over 100 nm pores after releasing step: So in this image, we can see that there are a lot of beads…
One of the surprising results of Jiracai’s studies with thick and thin membranes was that the thicker membranes had a lower capacity to support back pressure than the thinner membranes he used (see table in this post). This is counter to our original expectation; Since we know that much thicker EO membranes can support 50…
Hello everyone! The new FEI Osiris TEM system has been finally setup recently. With the new purchased Gatan single tilt heating holder 628, we were managed to do an in-situ heating experiment with the Osiris system last week. We used the same sample OSO201510, which was used in Harvard, to test this heating holder as…
