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.

Conventional tissue culture substrates do not accurately emulate in vivo surface conditions. This project involves the development and characterization of a polydimethylsiloxane (PDMS) substrate for cell culture. PDMS is an important biomaterial due to its optical transparency, biocompatibility, and variable elastic modulus. ADSCs and HUVECs were used to analyze spreading and proliferation on PDMS-based substrates of…
Inspired by some recent literature that I have been reading, I decided to add an argon bombardment step after the amorphous silicon deposition step by applying a 50 W substrate bias. The idea is that point defects on the surface of the a-Si will become seeds for crystallization and thus lower the crystallization temperature and…
Tom recently designed a wafer with 1cm2 chips containing a 2×2 array of 1mm2 square membrane windows that fit on 384-well plates. I wanted one of these chips to get a preliminary data image for my R21 application. Instead, I saw something much cooler. I plated bEnd3 cells on the pnc-Si side of this chip…
Hello everyone, this post is a summary/recap of the MRS Spring meeting that was held in Phoenix, Arizona this past week (April 17 – 21). Here is an overview of two sessions: Molecular and colloidal plasmonics – Synthesis and applications (ED14) Jennifer S. Shumaker-Parry, Associate Professor at University of Utah (http://shumaker.chem.utah.edu/) Combined top-down/bottom-up for the fabrication…
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…
Purpose: Study the hemocompatibility of different substrates using platelet activation as the indicator. Extraction of platelet rich plasma (PRP): PRP were prepared from whole blood following the standard protocol outlined by Abcam (http://www.abcam.com/protocols/isolation-of-human-platelets-from-whole-blood). To describe briefly, 9 mL whole blood was centrifuged at 200g for 20 minutes in a 15 mL Falcon tube to obtain…
