Committee Meeting presentation

This post is not an update on my research. I am creating this page to house download links to the COMSOL Multiphysics models I’ve constructed in the course of my work here in the McGrath Lab. This page is linked to in my thesis for legacy purposes. Important: these files have been uploaded with the…

We’d like to get verification of the absorption spectra of our npAu/npMgF2 SERS structure. The SERS effect should occur where the absorbance is maximized. Total Light = Absorbance + Reflection||Scattering + Transmittance Last Friday, I had the opportunity to work with Jennifer Kruschwitz who possesses a Konica-Minolta integrating sphere spectrophotometer from 380-740 nm (10 nm…

Hello Everyone, This is another quick update over our experiments. Exosome Scale Experiments:  In all of our experiments, beads are 100nm and pores are 80nm. As you probably remember, in my last post, i talked about hos the membranes are resisstive and they don’t stand these flow rates, so the flow finds another source in…

Update: After doing several measurements again, it appears that the data shown below were not repeatable.  It is believed that these data were just the artifact.  Please see my new blog post “Flow Sensing and Energy Harvesting Capabilities of NPN Membrane” for a new data set.   Here are the streaming potential measurement data for NPN membrane…

Thanks to our collaborators at the University of Chicago we have now used NPN to demonstrate sodium/hydrogen exchange functions at the level of single EVs. This is first-of-a-kind evidence of protein function in individual EVs. It will be officially published in Communcations Biology and will soon be located at this DOI. What follows are key…

I have been using MatLab to analyze the pores in the SC wafers. Here are the results from my analyses: To take a first look, I simply plotted four characteristics: average pore size, porosity, cut-off pore size, and mean roundness against the wafer number. Notice that the blue dots are the b wafers. Excel would…
