SONY backing organ-on-a-chip development

Goal: Measure SU-8 shrinkage that have gone through various soft and hard bake conditions To measure the shrinkage, the SU-8 scaffolds needed to be lifted off, but there was some issues. Originally, the SU-8 was spincoated onto an oxide layer, which would be etched away using BOE. The SU-8 had appeared to be disintegrating due…

There are two longitudinal studies for Chronic Kidney Disease (CKD). Ancillary studies can be set up to share the collected data, bio samples, or even request additional data to be collected. These Ancillary studies can be funded through normal channels, NIDDK, ASN, VA, etc. Approval to use the data should be requested 3-4 months before…

This post includes some optical and SEM micrographs of a SiO2 membrane patterned by nansosphere lithography using 300 nm polystyrene beads. An SU-8 microgrid was deposited on top and the membrane was released by dissolving a bottom layer of ZnO. After the release, the membrane is rinsed in water and transferred to a clean substrate….

Summary There’s a lot to be desired in counting pores in grayscale images, especially when the contrast differences are low. A human eye is usually much better at picking out slight differences in contrast, and this can mean the difference between an open and closed pore. Differences of 5 nm can be significant in certain…

In Episode 3 of this series, I have begun working towards improving my COMSOL modeling for particle capture. In addition to running simulations, I need to run experiments to try and correlate real world solutions with simulated results. One of the major focus points of my work has been trying to explain the shape of…

The presented post is somewhat of a follow-up of this previous post, in which we studied the adsorption of proteins on silanized NPN chips. In the presented work, we study the adsorption of fluorescent proteins (BSA and IgG) on both the untreated and the PEGylated nanoporous nitride membrane (NPN) chips using epifluorescence as the imaging…
