Hello Everyone, So as you probably remember, we were able to show the capturing and releasing successfully.   In addition, we have a Matlab Code now which helps us for intensity change, so as you can see in the next…

For the past few weeks, Henry and I have been working with human dermal fibroblast cells and 3T3 mice fibroblast cells. We have been working to quantify wound recovery in hopes to be able to incorporate exosomes from different cell…

Thanks to UR cleanroom and Jim Mitchell, we finally have a better way to deposit the ZnO film that our fabrication process uses as sacrificial layer. Below is a quick comparison of the previous ZnO deposited by sol-gel and the…

Summary Surface roughness is believed to impact the SERS effect. Rougher surfaces tend to produce more SERS activity. We can manipulate the npMgF2 surface by changing the deposition temperature, in the form of changing the grain nucleation, shifting the overall…

Hello Everyone, This is another quick update over our experiments. Exosome Scale Experiments:  In all of our experiments, beads are 100nm and pores are 80nm. As you probably remember, in my last post, i talked about hos the membranes are…

Summary My analysis of npMgF2 has relied heavily on both tomogram and segmentation processes. The tomogram generation has thus far been sufficient, giving enough detail to our eye to identify different structures, but turning the tomograms into 3d models has…

Introduction/Motivation Endothelial cell adherence mechanisms are well characterized in literature to date. Endothelial cells, such as HUVECs, interact with their substrate as well as surrounding cells through focal adhesions (network of proteins involved in cell adhesion; vinculin, talin, FAK, etc.),…

I am developing a process for fabricating microporous Parylene Liftoff membranes. I am interested in these as a more flexible substrate for cell culturing.  Parylene is relatively strong (compared to say pdms), so it is feasible to work with lifted…

Intro Understanding how the Au film coats the inner part of the npMgF2 is essential to understanding how the photonic properties of the npAu/npMgF2 sensor arise. From SEM, we are able to resolve little cones of Au, but unable to…

Many thanks to JK, Dean and Gunner (Webster HS) for compiling this table. Take homes … NPN-O has smaller pore sizes, lower porosity than NPN at the same thickness (50 nm). All materials have slightly asymmetric pores (~ R1/R2 =…
