Just wanted to show the detail of PETL channels. A couple of interesting things: The adhesive layer(s) are pretty thick, and look pretty smooth after heat curation. Also, the channels are slightly beveled, probably due to craft cutter blade.
Last week, I did another two wafers with different top oxide thicknesses to verify my hypothesis about the top oxide thickness effect on pores. The wafers were 20/15/03(bottom/middle/top) and 20/15/40. According to the hypothesis, the porosity of 20/15/03 would continue decreasing, where for the 20/15/40 structure, the porosity might drop. Same tip I used before,…
In this gel I evaluated the linear range of coomassie brilliant blue. From this test it looks like things are linear from .0156 to .125mg/mL. My guess is that the protein ladder bands in the previous experiment fall within the range. I used the Bradford assay to find the total concentration of the stock protein…
First off – OK now on to the science. Wafer 747 has a huge amount of pinholes, and in this study I wanted to see how these pinholes would effect electroosmosis. I will show results here from two experiments with these holey membranes. These membranes have a lower rate of electroosmosis than previous tested membranes. …
WHERE: URMC ** Room # 4-7545 ** WHEN: Tuesday April 16th & Wednesday the 17th. TIME: 9:00-4:00 P.M. Please drop off your pipettors early as we expect a good turnout. Pipettors will be done on a first come, first served basis. Thank you!
Last week we processed wafers 335 – 340. Our goal was to track down the source of Cu contamination. We sputtered membrane films both at room temperature and at 400 C. Our thought was that the RT dep. would not show contamination if the sputter heater was indeed the source of our Cu. It turns…
“I’ve looked at clouds from both sides now” is a Joni Mitchell song. Some Background We are developing a white blood cell (WBC) detector to surveil peritoneal dialysate fluid during fluid exchanges for early detection of peritonitis. This preemptive monitoring is currently not available in clinical practice. The current detection method is by visual inspection…
