Thermal Stress and NPN Tent Transfer
From my last two posts (Anodic Bonding, Ozone Bonding), it is clear that we have some sort of bonding going on between the freestanding membrane and the posts intended to support the membrane. However, we do not understand the nature of the transfer. To gain more insight into this process, I took more SEMs of…
Membrane Edges with SEM
I was motivated to scan our membrane edges after looking at this image from the paper Maryna presented last week: I found a couple of pnc-Si samples with membranes still attached to the edges. I also found one sample with a membrane split almost down the middle. I coated the samples with 3nm of Au…

BMES 2018 Takeaways
ByAlecBMES – Atlanta 10/17/18-10/20/18 F-actin Alignment Quantification Using HSB Color Coded Maps ImageJ Plugin: OrientationJ Purpose: Quantification of F-actin alignment using ICC. HSB map provides a visual representation of fiber alignment with color codes related to hue:local orientation, saturation:coherency, brightness:fiber stain intensity (Figure 1). Our use: Quantification of HUVEC alignment before and after flow. Fluorescent…
Gold Trials
Most recently I’ve been working with colloidal gold nanoparticles (referred to as AuNP from here on). We chose to use AuNP for separations because it is an ideal hard sphere particle, unlike a floppy protein. We thought we could achieve more information about the cutoffs or the sieving characteristics of the membrane by using such…
Film Stress w/ SU-8
SU-8 3010 has been used to create a scaffold in the fabrication of the liftoff membranes. The supplier of the negative resist, MicroChem, rates it for a 13 moth shelf life. We were having difficulty achieving good liftoff with membranes in the second half of last year. The SU-8 had expired by several months, so…
