Discoloration presentation
I’ve prepared a few slides of discoloration data for tomorrow. The images didn’t copy over from the blog very well, but I think they are good enough for a discussion.

Interesting features
In an effort to measure the effects of bsa adsorption on pnc-Si, I made some samples from SC 073 (a good wafer for separations) and with the help of Graham Marsh (Waugh Lab), looked at them using AFM. We did our first studies of the samples in water, just in case that drying somehow distorted…
Air Permeability Update
I found a small mistake in my calculations of the air permeability.Corrected data is in the graph below.
Study Proposal:In Vitro Cell Adhesion: Whole Blood, Single channel 5.4 mm chips
The purpose of this study will be to compare the cellular adhesion on PEG vs Bare nano porous silicon nitride membranes using the same fluidic devices as the in vitro clearance study. The devices will need to be disassembled for imaging. Materials: 6 chips, 3 PEGylated, 3 Bare. gaskets for 6 devices Tygon tubing 2…
RTP + Silanization
After recent studies with surface treatments, we wanted to take a step further by trying amino silanization on RTP’ed samples. Wafer 413 samples were RTP’d with no intact slits. Both 2D and 3D formats were tested in DMEM (-FBS) in oven @37C. All 3D samples had membrane side facing down whereas, in 2D format the…
Repeated Success with Flow System
ByMike HYesterday I started a test to try and reproduce the results Henry was able to obtain with a closed flow system last week. Using four samples (W619) I ran the UV Ozone bonding process and allowed them to sit over night. This morning I found that only one of the four samples was bonded; recently…
In-situ heating experiments on the OSO and NSN samples
ByJoe QiI have been working on the in-situ heating experiments on the free-standing membranes in the past few weeks. After quit a few times attempts I finally have some good videos made from the TEM images that were taken during the in-situ heating process. First I’ll introduce the background of these two videos including sample info,…
