BSA detection on NC
Creating an array to hold a pnc-Si wafer to proving to be difficult. The PDMS spreads too rapidly though the NC to form a consistent array for the pnc-Si membrane (and eventually wafer) to rest on. I’m still running different trials of the PDMS on NC to see if I can get the array to…
R6G diffusion observed through the plastic substrate
ByJimThe only problem is the diffusion is very fast with defects in there.
Aline Devices for Cell Culture
ByAlecIntroduction I am working part time in collaboration with the Schwarz lab (CMSR, University or Rochester) on a bacterial migration project that includes the use of SimPore’s membranes. In order to increase throughput, Aline was contracted out to manufacture multiplex devices designed by Jim, Elysia Masters and myself. One aspect we would like to probe…
Micropump Calibration Curves
ByMike HThe controls of the micropump are in units of frequency, voltage, and wave form, not in flow rates. Based on the manufacturers website they claim that the flow rate has a linear relation with voltage. I took some time to create calibration curves at two fixed frequencies (50Hz and 150Hz). I simply allowed the system…
WordPress updates
I’ve upgraded the WordPress publisher to version 2.6. The most useful change is the ability to track changes to any post/page, compare revisions, and revert to an older version. Here’s a video showing the changes: https://videopress.com/v/mARhRBcT/fmt_std Additionally, I’ve installed some plug-ins that should make posting and keeping up with new posts easier: There is now…
Smith Lab Diffusion Studies
Harold Smith at the Med Center proposed an experiment for Jess and I to try, in which we use our membranes to separate proteins onto a PES, PVDF (Polyvinylidene fluoride) or Nitrocellulose membrane, similar to a Western Blot of DNA microarray. The idea is to create a system to screen for drugs that break protein-protein…
