For the first time, we did time-lapse phase microscopy (1 frame / 5 seconds) looking at endothelial cells through the ITO in the static BBB device (device A bottom left well) and measuring the TEER concurrently. Here’s the video, just…

ITO + Circuit Ink Simple Biocompatibility Test with Yuchen Wang
We grew some endothelial cells on ITO and glass slides to see if there were biocompatibility issues. We also put some of the thermally cured circuit writer ink afterwards to see if they were cytotoxic. Two devices were constructed: one…

Permeability Graphs for BSA Separations with Variable-Active-Area Sepcons Show Flow is Independent of Fractional Active Area
What I had in my two previous posts described as permeability graphs were in fact total volume passed/ total time passed graphs: What I thought I saw was that cake layer formation was dependent on the filter geometry. There is…
How water sticks to surfaces
Tejas found this… A cool article and video on water ‘sticking’ the surface. Notice the difference in advancing and receding angles. http://web.mit.edu/newsoffice/2013/droplet-surface-adhesion-0219.html

A New Round of Separations Still Shows an Increase in Filtrate Flux Above Normalization for Larger Active Area Sepcons
Using methods pretty much identical to those outlined in Tuesday’s post, I was able to get very similar data for a different BSA concentration. Whereas Tuesday’s curves were all done with 1mg/mL BSA, this was done with 0.5mg/mL BSA. The first…
