Spectrophotometer raw data

I’ve taken fluorescence measurements with the fluorescence microscope on PEGylated and unPEGylated glass coverslips and SiN chips. Six coverslips and six chips were prepared. Samples were treated exactly the same, save for the fact that half the samples had PEG Silane in their treatment and half did not (though they were still bathed in toluene…

Wafer 416-T is a TEOS wafer annealed at 900 C. Pinhole density is relatively low. left: (1,0) @ 35kx; right (0,4) @ 35kx left: (1,0) @ 50kx; right (0,4) @ 50kx

In attempting to generate control systems for our exosome work as well as to potentially develop a system that would help some collaborators at the University of Illinois, I have been working with the ultracentrifuge again to hopefully isolate a pure fraction of exosomes, devoid of any protein components. This would allow us to start…

Over the past month, I’ve posted some results of a colorimetric assay for silicic acid.  Previous posts are here and here.  These results showed that the assay detected silicic acid after pnc-Si and PSi degraded.  However, bare silicon wafers also yielded silicic acid, according to this assay.  Since pnc-Si samples have the Si well-side surface,…

We were worried that Friday’s experiments were giving us a false positive results. If the electrophoresis breaks the membrane, then we’d expect to see the rhodamine rush through just like it was in our experiments. It’s too hard to view the membranes afterward because they tend to break during removal. I designed some simple tests…
