Assessing the surface modification of NPN chip using XPS

I’ve run a few comparative studies with the CytoVu devices that have SiO2 membranes in them.  From a previous NRG discussion, here is the comparison of a single location with only the fluorescent images, and that same location but with phase included: In the phase image, the pores can be seen through the cells, especially evident in…

Scope: The purpose of this experiment was to determine which conditions are best for differentiating adipose cells into endothelial cells  and formation of networks. ADSCs were used for this experiment, variables included media and matrices. Geltrex and collagen were used as matrices for the cells, the bottom of the plate was used as the control….

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 DI or PBS. We are testing for what will make the most optimal cell culture…

Wafer 1148 was produced roughly around the same time that the wafer I used to make my oldest MgF2 material (wafer 1085) was produced. We know that some of the NPN material from that time was not etched all the way through, creating pores that look like a ‘bowl-with-hole’. I believe the shape of the…

For everyone conducting biological studies, this paper highlights how to think about sample size and replicates. It suggests using “SuperPlots”, which color codes data points from different experiments to better visualize the type of variability seen (i.e. random variability, experimental variability, etc…). SuperPlots: Communicating reproducibility and variability in cell biology Jim and I recommend everyone…

I’ve been on a Sepcon assembly binge, and I thought I would post my assembly statistics. On 12/15/13 (assembly “L”) I broke 28 chips out of wafer 1070. 3 chips were visually damaged by the break-out process, 1 was already defective. After inserting the chips into the sepcon housing, testing with 5 psi nitrogen revealed…
