The plan was to fabricate ~7nm pores on the PDMS-painted 200nm SiO2 + 20nm SiN chips and take IVs overtime, and observe the stability of the nanopore’s size. I fabricated a total of 8 200nm SiO2+20nm SiN chips using the…

[NOTES] BMES 2017 highhlights

Here is a summary of some of the talks I attended at BMES 2017, mainly from the Nano and Micro- technologies track. This is an ongoing post, I will post more comments, links, and figures. Anna Kalmykov (Tzahi Cohen-Karni) Carnegie…

Hello Everyone, So following up on my exosome scale experiment and my last post, i am presenting my last update to summarize my results and to show that my results are trustable and reproducible. This is how we take images:…

Hello Everyone, Kilean helped us to set a training session for NanoParticle Tracking Analysis (NTA) in UR Medical Center. For this training session, i had 4 samples including: Beads, Liposomes, Media + 10% serum, and PBS. Here  is a summary…

As the title states, these are images from the monolithically fabricated devices used by Kyle and Vincent in Ottawa. These devices were fractured with tweezers, then tilted and metallized with 5 nm of Pt, mounted on carbon tape.    …

I’ve now made 18 pores in monolith devices, with only 1 real success, which was the first one that I report on already. All of the rest have failed for various reasons, mainly relating to the silicon nitride membrane in…

The plot below shows a calibration curve to calculate the etching time needed during the RIE step (used to reduce the size of the nanospheres) to obtain a desired pore size. The membranes were patterned from nanospheres with a nominal…

As the title states, I have been making TEM images and reconstructions from a variety of NPN materials. I hope to correlate the underlying nanostructure with SERS activity eventually. These images show many different porosities, topographies and pore shapes. Wafer…

So Alec, Tejas and I will have a poster at the Immune Imaging Symposium in the Med Center on Nov. 4th and we created an image for our abstract that Jim requested I post here in higher quality. Immune Imaging…
