Last week I tried to diffuse Cytochrome C through our membranes onto PVDF and PES membranes to see if we can detect protein adsorption on the other membranes. The trial illustrated that cytochrome c will diffuse through our membranes and stick to the PVDF and PES membranes. I ran the experiment again, but I used…

Summary I need to replace the function of my breath to get water into the femtoliter sized cavity of the monolithic device. I achieve this using a small stream of ethanol vapor as a precursor, and then replace the ethanol with water. Once the chips are wet, they should be reasonably stable until they can…

In support of the bone infection studies done in the Schwarz lab at URMC, I have recently been tasked with coordinating a new collaboration with Dr. Yates lab in the Chemical Engineering department. The goal of this collaboration is to establish a method to coat our membranes with hydroxyapatite crystals. Two different methods were attempted,…

We have already established that bias is an important parameter in controlling the morphology of 15 nm thick pnc-Si, but have yet to look at its effect on thicker films. This week, made a few 30 nm thick Si films with 02, 05, 25, and 50 W of substrate bias. I annealed these films at…

Here is the most up to date figure that I’ve made to compare the simulated and experimental separation results.  I went back through the x-ray crystals and remeasured the longest distances in the molecules.  I used the radii to rerun the simulations and plotted them against protein and rhodamine diffusion data.  Here are the results:…

To identify how much of an effect the membrane has on particular simulations, we originally came up with the idea of using a phenomenological effective diffusion to view the membrane impact (see this post).  Here is the most up to date version of the figure, which was slotted for use in the simulated diffusion paper:…
