I attached a presentation here for tomorrow’s meeting. sensor

I decided to find another supplier for HBSS and found one: CellGro.  CellGro HBSS had the same components as Gibco HBSS, although a couple of the concentrations were different.  I tested out this new HBSS vs. homemade HBSS. Here, the…

Last week, we wondered whether the wells of pncSi chips created an unstirred volume in which an extreme environment could form (pH, byproducts), thus accelerating discoloration.  To investigate this, I placed one chip flat on the bottom of a plate…

I sealed track etched membranes into the usual E-Cell setup. Here’s a chart with the calculated flow rates: I’m not sure why the 50nm sample was so much higher. Maybe there’s a difference in porosity? Also this is only the…

In these discoloration tests, I looked at the components of HBSS.  HBSS consists of NaCl, KCl, 0.048 mg/mL Na2HPO4, 0.06 mg/mL KH2PO4, glucose and 0.35 mg/mL NaHCO3.  In a previous post, I showed that NaCl, KCl and glucose didn’t cause…

For this experiment, I looked into the stability of RTP treatment.  Specifically, I tested discoloration rates for chips at different time points after I did RTP.  The idea was to see if the beneficial effects of RTP depended on the…

We have two cutoffs for the Millipore Biomax PES membranes: 50kD and 30kD.  I tested the “EO” rates for both of these membranes and plotted them in this figure with standard deviations (3 trials  of 50kD and 4 of 30kD).…

Last week, JP deposited 25nm SiO2 for me on wafer 644 (which I cleaned in the UV/Ozone before I gave it to him). Unfortunately, someone broke the E-Beam that day and JP was only able to deposit on 1 side…

Jamie asked me to post these images of our membranes taken by Dr. Xiao Zhang from Hitachi.  They used a 300 kV tool to acquire these micrographs. The spacing between the atoms (striations) tells us the crystallographic orientation; most of…
