NxStage System One Now Cleared for Night Time Hemodialysis in Europe Posted: 19 Feb 2013 11:13 AM PST Hemodialysis is a time consuming process that typically requires multiple weekly sessions lasting a few hours each being stuck to a stationary device. The availability of at-home dialyzing has brought a new level of convenience to patients,…
A few weeks ago, Josh and JP brought me some 3 window microslit membranes that had edge aligned 8 and 9 μm slits. While these may seem to be quite large for most applications, they are in fact perfect for working with whole blood. The experiments that we have planned for these membranes are based on the…
Hello everyone, this post is a summary/recap of the MRS Spring meeting that was held in Phoenix, Arizona this past week (April 17 – 21). Here is an overview of two sessions: Molecular and colloidal plasmonics – Synthesis and applications (ED14) Jennifer S. Shumaker-Parry, Associate Professor at University of Utah (http://shumaker.chem.utah.edu/) Combined top-down/bottom-up for the fabrication…
I’m trying to find the best method to stain proteins on nitrocellulose, so we can easily see the protein on the NC membrane. I first tried Coomassie Blue which did not work very well with the NC. The Coomassie was too dark, as seen by the image below. Harold Smith gave me some Ponceau S…
This is something that’s been living on my knowledge page, but I think it’s a good idea to put it up here to get some discussion on it. Probstein gives the following equation for electroosmotic velocity in his book Physicochemical Hydrodynamics: U=-εζE/μ where U is the velocity, ε the permittivity, E the electric field, ζ…
Summary Since our last attempt, Greg and I have been attempting to refine our tenting experiments with the goal of demonstrating that we’re able to hydrate the volume underneath a nanoporous tent. This latest experiment is very similar to our previous experiment in theory, but we made some key changes which are discussed herein. Most…
