Kevin was kind enough to share his presentation with us from his visit this July: Here is the link on Owncloud: http://drive.bbe.23a.myftpupload.com/public.php?service=files&t=c3eceae62439a478b4d1b676924e45ee

Dave and I characterized the membrane samples using the 4-point probe system at Kodak research Lab. It is NOT the previously discussed micro-4-point probe. The spacing between two probes is about 2mm. We first tested a quarter bare wafer#388 at five points (see the diagram below). The average sheet resistance is around 80 ohm/square.sites (1)…
Our first attempt to “reverse” centrifuge materials using our standard 5-slot filters made of NPN from wafer 1070 are detailed in a previous post using GEN2 SEPCON assemblies. In this post we modify our method to more closely match the Sartorius Centrisart approach. To that end, we switch to using GEN3 SEPCONs because they are easier…
Since precision printing FITC KODE molecules into the windows of our 3 slot chips I have begun testing both the uniformity and the functionality of surface coatings of these molecules. In pursuit of coating uniformity I have tested several different methods of surface coating to determine which method provides the greatest uniformity. In this same…
Optimization of the PLL-g-PEG coating on SiO2 substrate: The first goal was developing an efficient method for PLL-g-PEG coating which provides a high density of PLL-g-PEG grafting on SiO2 substrate and effectively prevent cell adhesion. To achieve this goal, different concentrations of PLL-g-PEG in 10mM HEPES solution ranging from 0.1 to 0.9 mg/ml (0.1, 0.3,…
This is the first set of studies to assess the hemocompatibility of pncSi surfaces based on the paper by Fissell and Roy. It looks for the behavior of platelets in the plasma upon interaction with pncSi surfaces. Biological Motivation: Platelets are one of the most important components of the human immune system and also one…
Some transwell cell culture models require 1 week or more of cell growth in order to let the cells fully differentiate and form mature monolayer barriers. I had a couple of leftover samples a couple of weeks ago, so I measured the viability of cells on RTP’ed pnc-Si and PET transwells 7 days after plating…
