30 nm pnc-Si bias series
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…
stir cell
Art is going to make a second stir cell this week. I asked him to replicate it as closely as possible, however I’m not sure how well that’s going to work. The one we currently have is made out of Ertalyt, a material similar to teflon. Paul gave us polyethylene which is much softer than…
Seeing the Softer Side of Silicon: Polymer Coating Silicon Membranes Towards an in vitro Bacterial Infection Mimetic
With our virus sensor paper now published, my journey with virus diagnostics, at least for now, comes to an end. Keeping with the theme of modifying silicon surfaces for interaction with pathogens, I am now switching gears to developing models for bacterial infection. This is currently taking shape in an effort to coat our silicon…
Barcikowski Collaboration Rotation Project
As a rotation student from the Biophysics depart, I’ll be spending the next six weeks or so helping Dr. Stephan Barcikowski use the nanomembranes to do a number of separations as part of a nanofabrication procedure. Dr. Barcikowski makes extremely pure gold and platinum nanoparticles (~10nm) colloids using laser ablation and then bioconjugates them with…
TEM Tomography of NPN and npMgF2
Many, many thanks to Kilean Lucas and Brian McIntyre who enabled our metrology. We have desired to get 3d information about the structure of our nanopores. One method to do so is known as electron tomography, a technique which can reconstruct volumes and surfaces from sets of tilted images. By identifying dense regions of contrast…
SEM images of exosome scale experiments (After Releasing)
ByAslanHello Everyone, Following of making figures for our first exosome paper, I needed to have SEM images after releasing step. So i ran another experiment and checked the membrane after releasing step. You can see the SEM images of this step: As you’ve probably noticed, compared to after capturing step, you see less captured…
