Temp-controlled 'nanopores' may allow detailed blood analysis

I constructed a plot of hydraulic permeability based on the flow rates that Sterlitech has predicted for their membranes. Looking at the permeability values that I posted last week, outside the tested that appeared to leak, there was a 0.01um membrane with a permeability of 33.4, two 0.05um membranes with permeabilities of 59.9 and 71.1,…

In pursuit of an extremely sensitive biomarker capture sensor, I have been tasked with chemically functionalizing the surface of our membranes. Our end goal is to attach antibodies to the surface of our membranes which can be used to selectively capture target antigens at a wide range of concentrations. Focusing on low concentration ranges in…

To try to calibrate the STED for imaging on our membranes, Bill and I have been trying to use 50 nm silica beads that have been captured on the membrane. However, we discovered initially that the beads were actually not too easy to work with and clumped like crazy. On STED, we weren’t really able…

Hi everyone, this is a short post quickly detailing some interesting quirks of different wafers as their respective chips are subjected to a control experiment (1x PBS, Qs = 30 ul/min, Qu= 10% Qs every 45 minutes). First, lets look at 1256 (2.7% porosity, avg. pore diameter 33.2 nm). These results are a nice baseline…

On May 13, Jim McGrath and I are hosting Vincent Tabard-Cossa from the University of Ottawa. We will be interacting with Vincent as a sort of NRG mini-retreat day. See the information below.
