Just wanted to post an update on the creation of a counter flow system using the pncSi chips from wafer 619 (the wafer with the etched trenches for the insertion of capillary tubing). Over the past few weeks Henry and I have been able to produce a few functional counter flow systems using UV Ozone…
This is the second installment in a series of posts focused on the development of a method for measuring barrier permeability in the µSiM. In Part 1 we discussed the goal of making these measurements in situ at a position beneath the membrane. Because our preference is to use the trench down configuration in the…
A droplet (3uL) of 0.117 uM actin solution was added on membrane W303(0,2). Let the membrane sit in humidity Chamber for 20 min. Remove excess liquid. Add equal volume of Uranyl Acetate on membrane. Wait 90 sec. Remove excess liquid. Image was taken right after sample preparation. Xiao
In this experiment, I soaked membranes (from either wafer 1064 [150W deposition power] or wafer 1065 [100W deposition power]) in different fluids that are standard use in cell culture applications, or which provide a similar situation as could be found in such (cause of pH change, salts, etc.). Each membrane is made into a single-well…
I’ve always suspected that the pore formation process was very quick and to confirm this I looked at a wafer that was annealed for 10 s vs. 60 s. From the distributions, it would appear that the majority of pores nucleate and grow during the ramp and first few seconds of steady state. Next, I…
Pint Silicon Supercapacitor Tejas sent me an interesting article about Silicon-based supercapacitors. I have made a previous post on potential uses for our membranes as separators in EDLC (electrical double layer capacitors), and one of the problems I posited was that the electrolyte chemistry seemed particularly inimical to silicon (KOH, Na2SO4). The authors in…
