Confocal Analysis of Apical and Basal ICAM-1 Expression Following Polarized Cytokine Delivery










I coated the pncSi samples from W683 (no RTP) with Bovine Serum Albumin (BSA) in Tris-EDTA buffer. Three different concentrations were used: 1 mg/ml, 5 mg/ml and 10 mg/ml (usual range of BSA conc. used for coating Si surfaces). The samples were left in BSA solution for 45-60 mins at room temperature and almost dried,…
All electrokinetic phenomena are connected by a form of the Helmholtz-Smoluchowski equation. In the case of electroosmosis, the equation can be written as follows: where v is the velocity (in m/s) of water flow through the pores, epsilon the permittivity, E the electric field, zeta the zeta potential, and eta the viscosity. Since we do…
There’s been some discussion on whether furnace-annealed-only wafers are more uniform than RTP’ed ones. Today, I looked at several samples from wafer 304 (FA 1000 C) at different positions along the y-axis. (0, 5) – 25kx (0,2) – 25kx (0,1) – 50kx (0, -1) – 25kx (0, -4) – 25kx There’s a clear change in…
Objective: Determine the minimum required area and number of exploratory cytoplasmic protrusions for sensing ECM alignment and causing cell polarization. Hypothesis: Cells only need to sense collagen alignment through exploratory protrusions extended during initial phases of cell seeding and not throughout the entirety of the cell, and a minimum number or size of protrusions is…
Images of the nanoporous nitride wafer. The same wafer that Josh declared as having 30% porosity with an average pore size of 80 nm (or something similar). Josh put images and such on basecamp for those who have access. These numbers are for a TEM grid from near the outside edge of the wafer, where…
As an introduction, my name is Alec Salminen. I received my BS in Biomedical Engineering at the University of Arkansas and am currently in my first year of the BME PhD program at the University of Rochester. As my rotation in the McGrath lab gets underway, I would like to share with the group my…
