Original Contact Angle Study

So Alec, Tejas and I will have a poster at the Immune Imaging Symposium in the Med Center on Nov. 4th and we created an image for our abstract that Jim requested I post here in higher quality. Immune Imaging Abstract Image_01 The image is so high quality that it was having trouble loading into…

Our two O2 regulators arrived this week (it figures we would have two to arrive within a day of each other after waiting for weeks to have one). Tom and Lingyun got to work right away. The image below shows that the UV/Ozone system does reduce the contact angle dramatically when used with oxygen (recall…

Dialysis Rate: 10 mL/min, Péclet Number: 1, Membrane Width: 700 µm, Channels per chip: 17 Péclet number Pe ∝ H Pe ∝ 1/L Pressure Drop, P P ∝ 1/H3 P ∝ L

A couple weeks ago when I presented at lab meeting, Angela Glading suggested that I look at epithelial cell vacuolization on transwells.  This was in order to determine if vacuole formation was endothelial cell-specific.  If I’m remembering correctly, the rationale was that the vacuole-less fibroblasts I showed were not contact-inhibited cells and thus not a…

I recently bought some slides of ITO from Sigma-Aldrich, and have been working to integrate them into PDMS by using the same process as I did for the glass coverslips (seen here) The main differences between the glass coverslips and the ITO coated microscope slides are the ITO film, which seems to have different wetting…

  I have been looking into PLA (Poly Lactic Acid) plastic for use in our microfluidics. PLA is a commonly used material in 3-d printers, so it would be great if we could print out our microchannels for cell-culture devices. To that end, I wanted to see if the PLA plastic would react with our…
