Dear McGrath Lab members,
I would like to notify you that BME245 (Biomaterials Lab) students will be coming at following times (see below) to use the plate reader. They will be accompanied with experienced TAs at all times.
Wednesday- 3/26- 3:25 pm-9pm
Thursday- 3/27- 9:30 am-12:25 pm and 3:25 pm- 6:05 pm.
My apologies for any inconvenience this might cause. I appreciate your help very much.

Barrett Chamber Flow Visualization For my lab rotation here, I was tasked with visualizing the flow of blood/blood-like objects across the 1st generation Barrett chambers. The design of the chamber is seen below. Some key characteristics are that the chamber is suspended from resting flat on a surface to allow liquids to diffuse through the…
I’ve been trying to make the following device work for the past few years: The people who have been studying this have been trying to use the phenomena to mix solutions, or using arrays of mismatched electrodes to generate a sort of conveyor belt pumping mechanism: My idea is to use the electrokinetic phenomena of AC…
A paper by Munch (from Kodak), Zestar, and Anderson in J Mem Sci (1979) writes that charge has a big effect on albumin separations in track etched membranes. They show in their paper that they can make the theoretical sieving match the results better if they simply add the Debye length to the molecular radius…
We’d like to get verification of the absorption spectra of our npAu/npMgF2 SERS structure. The SERS effect should occur where the absorbance is maximized. Total Light = Absorbance + Reflection||Scattering + Transmittance Last Friday, I had the opportunity to work with Jennifer Kruschwitz who possesses a Konica-Minolta integrating sphere spectrophotometer from 380-740 nm (10 nm…
I am attempting to manufacture a range of npMgF2 thicknesses as demonstrated in my recent CCD post. Yesterday, I undershot my thicknesses substantially, I believe because of construction vibrations in the building. However, this results in some of the thinnest npMgF2 structure I have ever been able to image. I was targeting 15 nm, but…
Inspired by JP’s work with the Veeco Wyko, I attempted to fit pressure-displacement curves with the equation for thin film deformation (Vlassak and Nix 1992) for two membrane geometries: 100um x 100um and 1000um x 1000um. The relationship between displacement and pressure is: P = pressure, d = displacement, C1 and C2 are geometric coefficients,…
