Upping the ante
I guess we weren’t sure if I was actually drawing rhodamine back through the membrane or just bleaching it. So I made a new apparatus which consisted of a sawed off sepcon mounted on a slide with channels etched into the lower plastic of the device to connect a pbs resevoir on the slide to…
BBB Device V2.4
I have created a successfully sealed flow chamber with this current device (V2.4), with the caveat that I sealed off the top chamber and was unable to test leaking from the top to the bottom. Again, the dialysis chips from Dean’s work were used, as well as the same bulk microscope slide electrodes. Improvements…
PEG Mono-layer Detection on Crosslinked Oxide Chips
Below are the results of my recent crosslinking efforts. PEG with 1.5% crosslinker was exposed to UV light at varying times through a bar printer/transparency mask measuring 100/200. In theory this corresponds to 100 micron PEG bars and 200 micron openings. In practice the results are much less neat. The table shows HUVEC cell attachment…
Stock Pile Experiment
This experiment is to determine if the time between the SC1 clean and when the wafers get deposited matter. Currently there is suspicion that an SC1 from an RCA clean should at RIT should be done right before deposition, . So what is done typically is that lithography steps are done weekly at RIT to…
Update on NPN Liftoff
This is a summary I wrote ~3 weeks ago of the work Josh Miller and I are doing under the CEIS grant for NPN Lift-off. Summary: Josh and I have been working for about four weeks so far on this program. During that time we have done preliminary lift-off (LO) tests on two wafers: one…
Latest 2-chip Small Animal HD results
While the latest small animal studies was meant to be a test of the new 1-chip bonded HD devices, device failure resulted in the use of the older 2-chip 10-channel HD devices as used on previous experiments. Here is all the data, Sham, commercial, 75 nm NPN trial 1 and trial 2. Trial 1 had…
