Jirachai’s recent post on the formation of Au nanoparticles on the surface of the NPN is very exciting. For one, it is a very dense monolayer of particles. This self assembly mechanism is magnificent whereas if we tried to dry…

It was expected that heating up the substrate during Au sputtering would help increase mobility of Au into nanopores so that the uniform coating on pore wall could be achieved.  The result was quite unexpected; Au did not coat uniformly on…

After correcting a minor error in my code that was giving me some weird limiting behavior, and optimizing the code to give me faster results, I generated the following curves: Note that, as experiment predicts, the ‘sharpness’ of the graph…

Discoloration Assays Introduction: pnc-Si chips were monitored for discoloration to find chips that had not been previously RTP’d. These assays were necessary in order to find chips that could potentially be used for cell proliferation assays later. Setup: pnc-Si chips…

Hi All, Presented in this post is the following paper, titled: “Detection and isolation of circulating exosomes and microvesicles for cancer monitoring and diagnostics using micro-/nano-based devices” [REVIEW] exosome handling in micro and nano devices Keynote presentation: [PRSENTATION] NRG (2015-11-16) exosomes

Introduction After completing my experiments on burst pressure of HD membranes, I started the experiments on finding the burst pressure of 3-channel nitrite chips by using the airgas cylinder. This experiment is to investigate if soaking in viscous fluid will…

To supplement our upcoming manuscript, we decided that we needed to provide a visual of how thin our ultrathin SiO2 membranes actually are. To demonstrate the thinness of the SiO2 membranes, in comparison to the commercially available Track-Etched hanging membrane…

Update: After doing several measurements again, it appears that the data shown below were not repeatable.  It is believed that these data were just the artifact.  Please see my new blog post “Flow Sensing and Energy Harvesting Capabilities of NPN Membrane” for…

The below figure has three different sieving curves. Solid lines are model calculations assuming a SiN membrane with 37 nm pores, and either 0.4, 1.3, or 5 PSI applied to drive the separation. Markers are real data. Note that the…

A little while back I posted a design for a capture device that would (nominally) work for dialysis on real patients. Due to strict requirements to avoid clotting, the design included a lot of curves and nuanced structures that would…
