W502 and 504 were tested for burst pressure and air permeability. Only one sample from W502 was tested for burst pressure (the other broke while setting up and I wanted to conserve samples) with a burst pressure of 4.46 psi. The burst pressures for W504 ranged from 2.06 to 6.57 (n=3). Air permeability is shown below.
I’ve been working recently with amyloid-beta (AB) provided to me by some people in Brad Nilsson’s lab. These experiments are related to the HMM diffusion experiments for our collaboration with Harold Smith. Basically, AB fibrils are very long (microns) and we are looking for ways to either prevent their aggregation from smaller peptides/oligos, or to…
It has been a constant theme in our EO efforts as well as our energy harvesting efforts that our electrodes need to be as close as possible to the surface to see an effect. In Jess’s early EO work, we found that our chips could be used as EO pumps that were vastly more thermodynamically…
After a few more revisions of the micro pump, I performed a significantly more thorough characterization. Flow rate was determined as before using a horizontal capillary of known volume and a stop watch. A extremely small thermocouple was inserted into the PDMS substrate directly adjacent to the fluid outlet channel emptying the…
On Monday I presented our progress on the hemodialysis project for the Coulter Foundation. They seemed very pleased with our progress and impressed with our team. Its a tough crowd and for the first time, I sensed they had confidence in us. I’ve uploaded my presentation to the blog (PDF; ppt). Their primary points of…
Dave gave me some carbonized samples several weeks ago to test stability/discoloration. I measured the contact angles right after I got the samples (posted here) and then started the discoloration. These are SC141 chips. Controls were untreated (1st column) and RTP’ed only (2nd column) chips. Two carbonization conditions were tested – 5 minutes of 1…
Introduction This post provides an update on a series of experiments conducted with Sam. These experiments were designed to assess the versatility of the CAD-LB platform for detecting EVs in urine samples. Urine is a complex biofluid often used in clinical diagnosis, making it a suitable subject for testing the CAD-LB’s biomarker detection capabilities. After…
