Metallized Membranes

“Three ways to build an artificial kidney” This IEEE Spectrum article list three efforts to make an artificial Kidney. The first is the AWAK, kidney on a belt. They don’t have the latest images for this, only the original very bulky design. The second is the Roy/Fissell implantable Renal Assist Device (iRAD). Both of these…

This is part three of a series of posts on constructing a mathematical model of the movement of gold through a porous membrane. In part one, I implemented William Deen’s mathematical model of the electrostatic and steric effects that contribute to whether a gold nanoparticle will translocate through a pore. The mathematica and matlab code…

In most of the images I’ve posted of bEnd3 on pnc-Si, it seemed like there were more cells crowded onto the free-standing pnc-Si compared to supported pnc-Si.  This post shows that this is indeed true. To do cell counts, I stained cells with Hoechst 33342 (1uM in media) for 15 minutes @ room temperature and…

I got some wafers from Chris last week(?) that had undergone different Megasonics cleaning treatments by the manufacturer.  We’re trying to figure out if these treatments are actually cleaning the wafers.  I’ve been having trouble getting the AFM to stay in the “right” mode for imaging with these wafers.  However, I have gotten some images….

Previous Post on Water Permeability Figure We decided at the last meeting to show water permeability for each membrane used rather than plot for a specific characteristic like porosity.  I did this but there were a few samples that still had a noticeable deviation between experimental and calculated permeabilities.  I asked Dave to reprocess the…

Maryna told me the UV/ozone cleaner did not work (the blue light in front of the chamber did not light up) when she was working with Dave today. I quickly checked the machine and it is actually working properly. The trick is to make sure you trigger the “safety lock” behind the chamber before you…
