I’ve been attempting to simulate protein sieving using the COMSOL model.  This first figure shows the comparison of the simulated separations to the actual results as determined by gel densitometry. The simulated separations tend to lag behind the experimental data for smaller proteins.  This is surprising since the simulation is faster than experimental results for…

In my previous post talking about the contact angle measurement of 3-mer coated PEG, there was a lack of adequate controls, and also an unanswered issue of contamination of samples during storage. I would now like to refine the study in more -controlled fashion, and without reusing the old chips. In addition, I am also…

Below are images from two samples that were annealed at 950 C and 1050 C post-EDP etch.  The lower temp anneal produced a membrane with many features that do not seem to penetrate the nc-Si.  There were a few (couple in each field) smaller pores ~ 10 nm in the outer samples.  This supports Jess…

Two years ago (blog post), I asked Professor McAleavey to help me see if we could use NPN chips to generate ultrasound. I’d found a paper (An exact solution of AC electro-kinetic-driven flow in a circular micro-channel) that suggested, given the geometry of our chips, that if the chips could be used to generate sound, they’d…

As part of my work over at the University of Nottingham, I’ve been using iBidi devices to grow cells. Eventually, I will use their product to do Raman studies of cells grown on my MgF2 substrates. I’ve been making some progress towards that end using PDMS (I’ve been using 10:1 base to curing agent for…

In the study, which combines the compressed sensing (CS) and the structured illumination microscopy (SIM) methods, an object plane should first be collected by a lens, and then the collected signal should be measured by a photomultiplier tube (PMT), located at the focal point of the lens. The recorded measurements present a measurement vector that…
