Nanopocket Membrane Fabrication-Update
Last week, I annealed a few amorphous 15 nm TEM grids in the RTP. We have always speculated that the stress from the bulk silicon was a necessary condition to induce pore formation and I wanted to confirm this. I picked six different temperatures: 600, 700, 750, 800, 900, and 1000 C. They were annealed…
Hemodialysis chips are not surviving the priming process and the 4 hour dialysis treatment. We want to verify that the membranes are being weakened and also to determine if coating with oxide will ameliorate the problem. Using single slot chips from wafer 1153 I performed burst pressure tests on three groups of chips. 1. Bare chips…
5nm BSA-Au appears to be 12.7nm.10nm BSA-Au is 18nm. Dilution dependent size change of 5nm BSA-Au. One theory for the size change was that residual BSA was combining with the Au peak and for some reason dilution of the BSA was causing a migration of the peak. This doesn’t necessarily make much sense as the…
I will keep this post short and start by saying that the process of establishing a reliable set-up for nanosphere deposition, by evaluating the repeatability of the deposition parameters, has been longer than anticipated. The nanospheres self-assemble at the hexane-water interface and stabilize laterally through electrostatic forces. The main deposition steps are: Add water to…
Hello everyone, for my first ever post I would like to share with you a collection of ideas that has turned into a review I’ll be working on. Here you will find some selected publications that report interesting fabrication processes at the nanoscale. I have summarized the processes and added some raw schematics of how…
Discoloration Assays Introduction: pnc-Si chips were monitored for discoloration to find chips that had not been previously RTP’d. These assays were necessary in order to find chips that could potentially be used for cell proliferation assays later. Setup: pnc-Si chips were autoclaved and placed in a 24-welled plate with 300uL of DMEM and incubated at…
