INT results from 4/3/13
I brought some 20nm and 40nm Sepcons to Integrated NanoTechnologies last Wednesday. First, we passed some short radio-labeled DNA strands through a 40 nm Sepcon, and then some longer strands. Both were able to pass through the membrane with a transmission rate of ~70% (as measured by scintillation), and the length of the strand did…

Combining Pores Affects the PoreImageProcessor, but Not Enough to Throw Permeability Off 2x
In Tuesday’s NRG, we wondered if the fact that some of Josh’s pores overlap could throw the PoreImageProcessor off enough to explain a 2x discrepancy between our theoretical hydraulic permeability and our experimental permeability (the experimental was lower). From this picture: I took the following close up: If we assumer that each of the sub-pores has a radius of…

Are those pinholes or micron-size pores?
Hello everyone! After a long time waiting and setting up, the new AJA and RTP at Vanderbilt University now are ready to go! Here are a couple of pictures of the new AJA and RTP. I have been working on testing the new AJA for a while with my old recipes. The new AJA system…

SiN-NP in 50 nm SiN
Using a 6″ wafer, we start with 50 nm of RV SiN, then deposit 40 nm a-Si followed by 20 nm of SiO2. RTP of 1050 C, 100 C/s, 60s. JP patterned the wafer to make standard SEPCON chips. The pores were transferred to the SiN using RIE. The RIE etches faster at the perimeter…

Using YES system for PEG deposition
It was decided during my rotation-review meeting to use a smaller PEG molecule (3-mer) for silanization of pncSi. Following is the brief description of the polymer. Boiling Point: 147-9°C @ 0.3mm Freezing Point: <0°C Specific Gravity: 1.16 Vapor Pressure, 25°: <0.1mm Vapor Density (air=1): >1…
