Introduction I am working part time in collaboration with the Schwarz lab (CMSR, University or Rochester) on a bacterial migration project that includes the use of SimPore’s membranes. In order to increase throughput, Aline was contracted out to manufacture multiplex devices designed by Jim, Elysia Masters and myself. One aspect we would like to probe…

JP and Josh Miller used the Xactic Si etcher to remove the pnc-Si from SiN-NP samples.  I believe they ran cycles until the samples looked visibly like SiN only.  Below are some SEM cross-sections showing before and after images of the samples. Sample 1028 with no RIE etch:   Sample 1036 with 20 s RIE…

Hi all!  Last time we have presented a theoretical perspective on the shear stress reduction enabled by our shear-free microfluidic system.  This time we will show an agreement between the shear-reduction predictions made by the analytical solution and a COMSOL simulation.  For details on the analytical solution please refer to the following post: [https://trace-bmps.org/datablog/2012/04/26/shear-stress-reduction-via-pnc-si-analytical-solution/] COMSOL…

Introduction This post is meant to introduce the new NPN-enabled slide-based devices produced by Ibidi. These devices feature an NPN membrane and microfluidic channels positioned perpendicular to one another formed by PSA and COP layers (Figure 1). Channels above and below the membrane allow for flow-based experiments including tangential flow filtration (TFF) such that biofluids…

The coating was done last week at RIT (it was postponed from two weeks ago because of the failure of the e-beam crystal sensor). I deposited 10nm Ti and 15nm Au, without vacuum breaking. All the samples are from wafer #313. TEM images were taken yesterday with the help of Karen. (Her machine is really…
