Wafer 416-T

My PhD exam was postponed (tentatively to early September but it’s up in the air still) due to an impending bureaucratic nightmare, so for the last few weeks I have been running more filter experiments, and I have discovered some interesting trends. While it is generally the case in nanopore experiments that the average dwell…

Here are the results of a protein ladder separation with w677.  If you recall, 677 is the 200um wafer that did not fit into the SepCons but had very few pinholes. S = Standards Ladder, C = Protein solution that never came in contact with membrane, R = Retentate, F = Filtrate Myosin (Band at…

I have been trying to fabricate my own Indium Tin Oxide (ITO) electrodes on coverslips for the BBB device in order to minimize the working distance for any microscopy. Currently, I am using microscope slides that are way too thick (mm). Coverslips are generally about 0.2mm thick. I am using a combination of sputter, photolithography,…

Intro Understanding how the Au film coats the inner part of the npMgF2 is essential to understanding how the photonic properties of the npAu/npMgF2 sensor arise. From SEM, we are able to resolve little cones of Au, but unable to see how rough/homogeneous/open the Au layer is. Our hypothesis is that these little cones of…

I ordered some new AC160 tips last week from Asylum and got on the AFM Thursday to test them out.  I think they solved some of the problems I was running into over the last few weeks.  Mainly, I was finally able to image entirely in repulsive mode (which was impossible with the older tips).  All of…

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. …
