Slides for Jan 12th STTR Update

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…

This is some preliminary data that I put into my F32 postdoc fellowship application.  It is a comparison of rhodamine transport through pnc-Si and PET transwells.  These studies were done with PBS as the buffer.  Sample volume = .1mL, donor volume = .3mL, receiver volume = 1mL, initial [rhodamine] = .5mM.  I set the experiments…

Just to double check the numbers I calculated on Tuesday I ran some wet-wet trials with 100K and 300K Nanoseps. Based on the wet-dry results we would expect that the permeability for the 100K Nanosep would be higher than that of the 100K Microcon. It goes without saying that the 300K Nanosep would also be…

PDMS/membrane deflection was measured on Veeco profiler by JP and me. The main problem with this kind of measurement is that it is taken form the backside of the membrane and the walls need to be excluded from the measurement. Using 20x objective helps but still has some problems. PDMS was first spin-coated on the…

In a continuing study on how a post-silicon deposition Ar sputter affects morphology, I annealed three 15-nm films for 10 s, 60 s, and 300 s. If you recall in my first report, I found that the Ar sputter increases the porosity slightly for a 1000 C RTP and dramatically for a 900 C RTP….

On Wednesday Feb. 12 and Wednesday Feb. 19, limited exposure dialysis was performed on rats. In the first experiment, blood was pumped with the peristaltic blood pump through a two-chip dialysis device in an acrylic fixture. The membranes were non-porous silicon nitride so no dialysate was included in the experiment. Blood was successfully pumped through…
