HI everyone, We continued working with Henry and Greg, gaining expertise on building chips and print-cutting channels.  Right now we have a bunch of chips made, some have been tested, and we have completed one of our objectives : To…

Over the weekend, I resubmitted our adult Adipose-Derived Stem Cell (ADSC) paper titled: Membranes Promote Endothelial Differentiation of Adipose-Derived Stem Cells and Perivascular Interactions There were three main findings: 1.) ADSCs can be induced to express CD31 (PECAM-1) like endothelial…

I went over to RIT to work with JP on measuring the deflection of NPN and pnc-Si membranes as a function of pressure.  JP and Dave Fang did this work years ago, and we want to pick it up again…

This past year I have been collecting burst pressure data on pnc-Si and NPN. The data for 30nm pnc-Si came from my previous post, “Wafer 1059: Burst Pressure Analysis”, which also includes a wafer map. This wafer had 7% porosity and…

With the help of Henry and Greg, the Fisher team has been busy learning the basics.  John and Ryan have learned some PDMS microfluidics-making and will have their first chips ready on Tuesday.  We have also been playing with the…

I’ve been going to considerable lengths to try and get reproducible zetapotential measurements from my streaming potential device. Zetapotential measurements are the closest we can experimentally get to measuring the surface charge of a membrane, and are important for three…

We are carrying out filtrations using wafer 1085.  We are testing the total volume of filtrate that passes in a given time.  We expect the total filtrate volume to decrease as concentration increases due to more immediate clogging.  Ultimately, we…

I am trying to create ITO electrodes for my microfluidic device for TEER measurement system. In my previous posts, I have shown that silver/silver chloride electrode, which is most commonly used in most commercial TEER systems, had killed the cells…

This week I’ve added male connectors to my device. Originally, I had female-female tubing connections to the device, which were very prone to leaking around the insertion ports. Tejas suggested that I try printing out the male connectors to combat…
