Nanoporous tent wetting fluorescence inconclusive

Hello Everyone, Following up the discussion that we had in my last post https://trace-bmps.org/sem-images-for-micro-nano-scale-experiments/about my SEM images after capturing and cleaning. It was suggested to tilt the samples and make sure that beads are inside the pores.    So I did a second round of SEM imaging on the same sample. And tilted images clearly…

This post is an accumulation of the results obtained from my research thus far. To recap, my intent (for my masters thesis) is to provide context for critical flux optimization in NPN microfluidic devices, particle capture, and compare critical flux in NPN to traditional track etched (TE) devices. Note that “critical flux” is the flux…

The results of my last diffusion experiment regarding BSA and filtered IgG (using SC 364) were inconclusive. (See “Diffusion Test– filtered IgG and BSA”) Looking at the histogram of results, there is no clear difference between the absorption of filtered IgG and buffer A. For this follow up experiment, I used SC 442. Of the…

This post is a recap on the nanosphere lithography based membrane patterning process. The results shown here are from a non-optimized run of the process. The image below shows an overview of the fabrication process used.   Below you can see optical micrographs of an etch test we performed on a TEOS sample with the…

Xunzhi from the Shestopalov lab gave us a brief presentation on how XPS is used to assess surface modification of the nanoporous nitiride silicon (NPN) membrane chip.   Power Point Presentation: surface assessment via XPS

I recently attended ASN’s Kidney Week 2017 in New Orleans. I mostly ate beans and rice, although there are three completely vegan restaurants and several restaurants with vegan options. The music was terrific and the weather was terrific, the people were terrific, etc. I had Five objectives for my trip to this conference. 1. Meet…
