TEM images of Ti+Au coated membranes (Wfr#313)

I have been working with Barrett to test two different assays with BSA. One is a standard procedure for microtiter plates and the other is a microassay procedure for microtiter plates. Here is a brief summary of each procedure: Standard Procedure for Microtiter Plates– linear range is 0.05 mg/ml to 0.5 mg/ml Prepare a diluted…

In this post I’m trying to give a better comparison among filtrations using chips from wafer 1085 using 20 and 100 nm fluorospheres, IgG, and 5 and 20 nm Au NPs.  In each slide I try to indicate the flow direction with respect to the membrane.  Unless I’ve written “Pressure” near the direction the separations…

Links and Papers: Article with video Lung on a Chip Device Paper Lung on a Chip Application (Pulmonary Edema)   Chris came across the publicity video last week and Jim asked me to look into the specifics. It’s a pretty nifty device. As the video shows,  the device is a co-culture structure fabricated entirely from PDMS….

For many months, Emma and I are trying to achieve neutrophil migration through endothelial cells and through the underlying collagen gel. I need to explain the details of my device first. The schematic is shown as below. I am using a 3 um porous membrane to allow neutrophils to cross the HUVECs in the collagen…

I first wrote about quantifying the pore formation process using kinetic theory last year. In this post, I will develop my thoughts a bit more. In the literature, researchers oftentimes present charts, like the two shown below, describing the Arrhenius behavior of silicon crystallization (Sontheimer APL 95 2009). Figures 3 and 4 show the crystal…
