Assessing the surface modification of NPN chip using XPS
Xunzhi from the Shestopalov lab gave us a brief presentation on how XPS is used to assess surface modification of the nanoporous nitiride silicon (NPN) membrane chip.

Intro Recently we have been collaborating with the Moghaddam lab from the University of Florida, which specializes in the fabrication of graphene oxide (GO) membrane, to study the use GO membrane as a toxin filter or absorbent in hemodialysis and live support devices. We are responsible for the hemocompatibility component of the study and used the following…
Last week I made a post about the troubles that a toluene-based PEGylation process presents to the PDMS in the CytoVu assembly. It was suggested that this issue might be overcome by replacing toluene with ethanol in the process, but I can report that unless I did something wrong (which is, I suppose, quite possible)…
This week, I did a systematic study on the growth rate of carbon on bare and aluminum oxide coated pnc-Si membranes. The bare samples were not treated prior to carbonization, while the alumina coated samples underwent a 5 nm treatment in the ALD tool. A bare and alumina coated sample were placed together inside the…
Tom gave me a few samples to scan on the AFM. PVP was added to the well side of the samples. I scanned the pnc-Si side of the chips to see if/how the PVP came through the pores. Samples were from SC114. Two different areas of supported pnc-Si membrane on control (no PVP) chip: The…
