There are two time slots:
10:45am-2pm
1:45-4pm
Please wear your I Love Nano shirts from last year. I have a couple more size Medium and one size Small.
The Rochester Museum & Science Center is on the corner of Goodman and East Ave.
MAKING CHIPS We now have our own SU-8 mold (with the help of Brian & Alex at URnano) and have started producing chips (see below) with our channel designs. Together with the chips produced last week, we have accomplish one of our objectives: To build a collection of chips for classroom use. With the acquisition…
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…
In continuation of the previous post, its been further observed that O2 RTP treated samples remain unchanged whereas the Ar RTP treated samples started to discolor after a week, as shown in the following images: In order (left to right)1. Ozone+Ar RTP2. Ozone+O2 RTP3. Control (Untreated)4. Ar RTP5. O2 RTP
Ultimately we want to use SiN-NP filters to separate viruses or some other biological species, but repeated attempts to pass 20 nm fluorospheres in water or PBS have failed. Au particles, however, have passed through the filters. This post reports the results of Sarah and I attempting to pass Au particles from 20 to 100…
I had some old HUVEC (P8) on pnc-Si transwells and PET Costar transwells that I didn’t know what to do with. So I tried a permeability study to see if there were any unexpected roadblocks in the protocol. I seeded HUVEC @ 50,000 cells/cm2 on PET and pnc-Si and allowed them to grow for 6…
About a month ago, I posted some preliminary data that showed NaCl diffusion through SC348. This was motivated by my observation of vacuole formation on SC348. Since my hypothesis is that cell culture substrate permeability is the key factor for vacuole formation, cells shouldn’t have formed vacuoles on SC348. Unless it is actually porous. This…
