After discussions with the gentleman in charge of surface functionalization at INT last week, Jim suggested that I attempt to pretreat our membranes with 0.1% SDS before a filtration.  The hope being that some surfactant left on the surface of…

Good morning, We received some messages from customer who are having trouble logging into their Matlab account. If you are having trouble accessing Matlab, please see below for your update instructions. If you continue to have Matlab issues, please contact…

This summer I’ll be working on preliminary development of technology that might lead to SiMPore drug discovery assays. The goal is to use SiMPore membranes to create much more efficient and generalized assays, which represents a big opportunity for the…

Can someone help explain this e-mail? Hey Jim – Just got a call from the locksmith who had a report from security that someone in your lab is tampering with the lock on your lab door…by doing what they’re doing,…

A new user in URnano has used the “old” susceptor for a ~270 C  (I might have the exact number wrong, but it is relatively low temp) to heat In on GaAs.  I don’t think there was ever a good…

Working on the development of PEG microarrays for cell heterogeneity applications. Current work has been accomplished on TPM coated glass coverslips. Transfer to membranes are in progress. Three different x-linker concentrations were tested in a 1:1 mixture of PEG and…

What process flows have I used to create my devices? Standard Cut out gaskets (10 min) Embed Electrode (face down) (3 hrs) Ozone Bottom, Interstitial, Filter and Top channels together (1 hrs, cure overnight) Ozone Bottom Electrode (1 hr, cure…

Dr. Webb is very interested in the thin nanomembranes that our group experiments with. To date, he has been trying to get cells to grow on SiN microporous material and image them with a few different types of microscopy (Phase,…
