Shear Free Chemotaxis Manuscript (Submitted to LOC)

I realized last week that I had made a pretty substantial mistake with my quantification which involved my mass standards.  Half way through running the gels for the previous study I had accidentally started making my mass standards at a higher concentration but counting them in the quantification as their initial value.  The bottom line…

Bill Bernhard’s group approached us about using pnc-Si membranes to separate DNA species by diffusion.  Bill’s lab studies the effects of ionizing radiation (ex. X-rays, gamma rays, UV light) on DNA using electron paramagnetic resonance (EPR).  There are three major species of DNA that they wish to study using our membranes: short oligonucleotides, larger supercoiled…

This is preliminary data for air permeability in track-etched membranes for membranes with different pore radius.For comparison here is a table of the performance characteristics for TE membranes Measured data is of the same order as official TE membranes data.

I have been trying to fabricate my own Indium Tin Oxide (ITO) electrodes on coverslips for the BBB device in order to minimize the working distance for any microscopy. Currently, I am using microscope slides that are way too thick (mm). Coverslips are generally about 0.2mm thick. I am using a combination of sputter, photolithography,…

The International Conference for Porous Semiconductors Science and Technology, 2014, was last week in Benidorm, Spain.  Jim was kind enough send me to represent NRG.  Dave Fang gave a great talk at PSST based on pnc-Si data in 2010. Here is a pdf of all the abstracts:  PSST 2014-Abstracts A quick summary would break the…

Introduction The glial fibrillary acidic protein (GFAP) is an intermediate protein released by astrocytes and has value as a  serum-based biomarker of neurological abnormalities including traumatic brain injury1. Inspired by the CAD-LB method for digital assessment of biomarkers on small extracellular vesicles, we sought to create a digital immunoassay for the detection of protein biomarkers….
