I used 100kD Millipore Celllulose membranes to separate the 2 C-dot particles. The results are similar to those I’ve obtained with pnc-Si; the 10nm particles pass while the 30nm ones do not.
Cy5 10nm particles:
Sulforhodamine 30nm particles:
Here are the sieving ratios:
| Particle | Ratio |
| 10nm (abs) | .60 |
| 10nm (fluor) | .59 |
| 30nm (abs) | .02 |
| 30nm (fluor) | .01 |
Paper can be found here I am working on developing an analytical model to understand how to accurately post-process the resistance values I obtain from my TEER measurements. This paper addresses a similar issue and comes up with a correction factor to match the TEER values obtained in a microsystem with the ones obtained from a…
In these trials, I used TER to look at the resistance between membranes with different amounts of pinholes. Finding a trend would produce a quicker way to scan for pinholes as opposed to checking each slot on the wafer with the microscope. The table below is my raw data. Wafer Number of Pinholes Resistance (ohms)…
Given the low burst pressures of recently produced wafers Chris requested I burst pressure test some samples in two different orientations: well side facing away from the positive pressure source and well side facing towards the pressure source. The standard protocol I follow is to test the samples with the well side facing the pressure…
I ran a series of serial dilutions with the rhodamine, to find the absorbency using the spectrometer. Below is a graph of the concentration of rhodamine versus the absorbency. I removed the concentrations which had absorbances greater than 1.7 AU because those absorbencies created a greater deviation. The lower concentrations show a more linear distribution….
If you’re a researcher or student using SolidWorks on an Apple Silicon Mac, you’ve probably run into the same wall: SolidWorks doesn’t officially support virtualized environments, and getting it to run stably in VMware Fusion takes some work. After extensive troubleshooting, here is the complete step-by-step protocol that got SolidWorks 2025 running on an M5…
After several months of modeling, experimenting, thinking and rethinking, it’s finally time to talk about the conclusions we can draw about nanomembrane ECMO. These conclusions take into account only blood oxygenation, and not blood decarboxylation, which is a different therapy that I have not modeled. You can find my description of the model here, and…
