New metal coated wafer#502
Wafer#502 was coated with 10nm_Ti & 15nm_Au on Friday.
I will pick out pinhole free membranes later today.
I will also try to get TEM images at Karen’s lab (medical center).
// The RIT clean room is closed this week.

Adding pockets (250 micron long, 76 micron deep) to the bottom of the channel (channel is 500 microns wide, 125 deep) in a 4 layer PETL (1 inch long chip) promotes disruption of laminar flow.
This is the first post I have made with respect to the project proposed by Mark Dumont of the department of Biochemistry and Biophysics. As a reminder of the scope of the project Mark has shown an interest in using our pnc-Si membranes to separate detergent from trans-membrane proteins during the process of preparing samples…
HI everyone, We continued working with Henry and Greg, gaining expertise on building chips and print-cutting channels. Right now we have a bunch of chips made, some have been tested, and we have completed one of our objectives : To produce chips for teaching. We also had our mask made and we will be…
During the recent visit of Greg Madeijski to our Institute of Biophysics, Imaging & Optical Science (IBIOS) here in Nottingham we had the opportunity to try imaging cultures of cells on several nanoporous membranes, including CytoVu’s and also the unsupported TEM grids without SiN. Here is a short summary of our adventures, along with some…
Hi all, this report will serve both as an update and a template for my upcoming BMES 2012 poster on the shear-free chemotaxis system. Introduction: Because of its capability in hosting reactions and transporting materials in small volumes, microfluidics enables the efficient processing of precious reagents. However, the shear stress inherent in the use of…
In this post I will explain how I tried to use the 1D diffusion model to check the results we had in the Nature paper. Unfortunately I didn’t get the same results in the simulation and I present some ideas for the discrepancy. In the Nature paper we made simple small volume diffusion chambers and…
