In order to address the fluctuations in the clearance data at the beginning of the long term treatment previous post The new protocol is as follows: 1. An inspected single slot dialysis chip is clamped into an  acrylic fixture holding PDMS ports with glass capillaries. 2. Ethanol is drawn into the device and the connecting…

How to use the McGrath Lab Surface Contact Angle Goniometer (SCAG) to collect image data for the established uses. Please refer to the SCAG Setup Protocols for assembly instructions. Note that the details of established uses will be covered in a future post.   General Notes Instrument Layout (See Protocols for SCAG Setup for more part…

How to prepare the McGrath Lab Surface Contact Angle Goniometer (SCAG) from a disassembled form. I will create detailed posts on potential uses in the future. GENERAL NOTES Based on the McGrath Lab SCAG as it was on May 16th, 2013 Instrument layout: All bolts and set screws are 1/4-20’s. The angle screws are 10-32’s. Loosely =…

Although the connection of those electrical circuits was always unstable, Greg and I did get some TEER measurement with this set up:   Device A Day 1 Day 2 Day 3 Day 4 Day 5 EVOM 1 -3450Ω* -1000Ω -1200 Ω -1000 Ω / EVOM2 100 Ω -9600 Ω 450 Ω -3 Ω 827Ω Device…

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 shy of 15 minutes of recording.  (reporting a low resistance: 5-10 ohms, shorted). TEER Test…

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 where cells were growing on ITO and another device where the cells were growing on…
