This paper was found when looking for details on quantifying cell spreading and adhesion. The paper discusses how the group has made mesoporous silicon wafers and their success with growing human umbilical vein endothelial cells on the wafers without additional proteins.
It is expecting that the high electric field gradient at the nanopore entrance could amplify the dielectrophoretic force so that the nanoparticles transported toward the membrane could be manipulated based on their polarizabilities. To prove the concept, the electric field was applied across the nanoporous membrane while a bolus of gold nanoparticles was delivered across…

For this post, Henry and I collected data for hemolysis and NTA sizing of soluble graphene oxide (GO). Hemolysis– prior work on the hemolysis testing of immobilized GO The purpose of the hemolysis experiment was to confirm that immobilized GO is the preferred from of GO for use in a portable hemodialysis machine. It…
I got a couple of wafers from Chris last week – 50nm oxide deposited at room temperature or 450 degrees. For each wafer, I saved the zsensor (top), phase (middle) and zsensor (bottom) scans. I also calculated the roughness (the table looking thing on the bottom of each image. I had some problems with imaging…
Thanks to UR cleanroom and Jim Mitchell, we finally have a better way to deposit the ZnO film that our fabrication process uses as sacrificial layer. Below is a quick comparison of the previous ZnO deposited by sol-gel and the new ZnO deposited by sputtering at UR. Hopefully, if you look close enough (or far…
I couldn’t really make sense of what was happening in this post, and in particular this figure threw me for a loop: So to help myself understand the relationship I whipped up a little matlab app to show the relationship a little clearer: Moving the sliding bar on the bottom changes the y-position…
