BBB On Chip (Griep et al 2012) Jascha sent me an article about a BBB device. Their device follows a very similar structure to that of the Booth and Kim paper, but closer to the optimized design that I created, using very thin, wide channels to generate a lot of shear stress (100 micron high,…

Last week’s production yielded six wafers, all deposited at room temperature. Here were the annealing conditions: Wafer 334, 343 – RTP @ 975CWafer 341, 344 – RTP @ 975C + FA @ 1000CWafer 342, 345 – FA @ 1000 C Pinhole density was moderate along the edges of the wafer, with one or two pinholes…

All separations are 30 nm (diameter) gold nanoparticles in a 56 nm pore setup, with other parameters as described in my last post. Y-axis scale bar is in meters, x-axis scale is meaningless (the simulation is 1-D, and the width is added just for clarity’s sake). The membrane is at y = 0. Color corresponds…

This is a summary of diffusion experiments with A3G that were conducted during the week of 5/10/2010-5/14/2010. The HMM structure of A3G is a large protein multimer held together with RNA. Since the ultimate goal of this project is to develop a screening assay for HIV drugs, a successful experiment is one that will show…

Intro Understanding how the Au film coats the inner part of the npMgF2 is essential to understanding how the photonic properties of the npAu/npMgF2 sensor arise. From SEM, we are able to resolve little cones of Au, but unable to see how rough/homogeneous/open the Au layer is. Our hypothesis is that these little cones of…
