Spectrophotometer raw data

If protein is adsorbing to a surface, it’s leaving the solution.  We can indirectly measure how much protein is leaving the solution, and that may tell us something about how much these surfaces are adsorobing. For my first attempt, I used the Bradford Reagent to measure the concentration of the solution after protein has remained…

This is a summary I wrote ~3 weeks ago of the work Josh Miller and I are doing under the CEIS grant for NPN Lift-off. Summary: Josh and I have been working for about four weeks so far on this program. During that time we have done preliminary lift-off (LO) tests on two wafers: one…

Here are some high resolution TEM images from a SiMPore-UIUC collaborator. Chris says: The high resolution stuff looks pretty cool, especially the zoom-in on the 8nm pore.  I the most obvious crystal planes are <111> with 0.314 nm spacing.  If you look carefully, some 0.192 nm <110> planes and 0.136 nm <100> planes can also…

With changing my channel height to attempt to lower the Peclet number, one important factor that is affected is the transmembrane pressure. Decreasing the channel height will significantly increase the transmembrane pressure, which may stress the membrane and cause it to break. However, in addition to changing the channel height, I will also be changing…

We will devote the first NRG meeting of each month to journal club. First up is Karl who will review two papers describing the use of single nanopore membranes as a method of characterizing particle size and zeta potential on a particle by particle basis. The technology produces intriguing data sets like the one shown…

Over winter break I put together some posters to hang up in the lab. I tried to represent in an clever way a few key areas of research that NRG is interested in:   If anyone has any ideas for more, or any suggestions for captions or improvements (I’m really not a fan of “At…
