Where to Change the Slide Show

I few weeks ago I posted some flow rate data based on the 100K microcons in which three of the four membranes worked fine and the other appeared to be a “dud”. I pulled the four systems apart and used the digital calipers to measure the membrane thicknesses and found the following. – The three…

For this experiment, 3um diameter pores were created using SimPore’s mask. Reactive Ion Etching was used to form the pores in the SiN. Both 25nm and 150nm TEOS oxides were used. An SU8 Structure of 10um lines with 100um square windows was chosen. A sample was placed in 10:1 BOE w/ surfactant for various amounts…

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…

I was not entirely satisfied with the amount of data that I received from my last burst pressure wafer, so I processed another wafer. This wafer had some yield loss initially, as well as window sizes that were slightly smaller than expected (by about 50 microns). We expect the mechanical strength of the windows to…

Hi all, i have to present for a biomechanics journal club meet next Friday (Jun/06/2014) and figured that i might as well double-dip the presentation.   Currently i am leaning forward to present this article: Takano (Futai) microfld nanofld 2012 [pocket-sized cell culture] which showcased a pocket-sized, stand-alone device for cell culture. No need for…

Two of my recent posts have dealt with my efforts to model ECMO and to experimentally validate this model. This post will describe the key change I made to my experimental system since my last post and describe my efforts to recreate the experimental results with my model — successfully! In an turn of extraordinary…
