Nanoporous tent wetting fluorescence inconclusive

We have recently been discussing the best way to analyze the diffusion and SepCon separation gels. In the following figures, I present line scans of the gels. These appear to be a bit noisy and are somewhat misaligned due to variations along the length of the gel. Blue = Control, Green = Retentate, Red =…

Here are the results of diffusion based protein separations at different salt concentrations and 50kD Microcons: We see a sharp cutoff between 31 and 45kD.  Separations look like they have progressed further in 10mM salts rather than 100 mM (this is the opposite of what we see in pnc-Si).  The 100kD data may also support…

Upload just for future reference. This includes the data of KMnO4 serial dilutions absorbance and the stir cell diffusion experiment.

This post is from Xuan ‘Sabrina’ Pan Purpose The nanomembrane used in my experiments is expected to promote efficiency of hemodialysis (HD) for end-stage renal disease patients. The membranes, however, broke during HD for rats, and breaking membranes can lead to unwanted consequences. My task is to figure out the transmembrane pressure during dialysis under…

Parylene-C is a biocompatible, inert, FDA-approved and nondegradable material, which can be used to fabricate mechanically robust thin membranes. Parylene is used in the medical device industry for coating implantable devices and in the microelectronics industry as insulator. Furthermore, it has been used in biomedical research for a wide variety of applications. In addition, parylene-C…

Looking back at production over the last year, I noticed that our porosity has dropped considerably.  Now that we have a good handle on controlling pinhole density, it is time to focus on controlling morphology again.  Below are two examples of a 15 nm and 30 nm pnc-Si film produced this month and one year…
