Analog-to-Digital Converter Design with the Photo Multiplier Tube
In the study, which combines the compressed sensing (CS) and the structured illumination microscopy (SIM) methods, an object plane should first be collected by a lens, and then the collected signal should be measured by a photomultiplier tube (PMT), located at the focal point of the lens. The recorded measurements present a measurement vector that…
Disposable PDMS diaphragm pumps
In order to include pumps on the prototype blood analyzer cartridges, it was necessary to implement a small pump using the existing knife-cut PDMS layer layup technique. The diaphragm architecture was selected due to ease of operation and minimal additional part requirements. CAD model of pump in Autodesk Inventor Bottom view of fabricated pump. The…

Pinhole Study: W510
To improve our knowledge of pinhole formation I have started counting pinholes on W510, W512, and W513. I also am playing close attention to areas surrounding the samples that have been completely etched, to see if this correlates to pinhole number. A schematic of W510 with number of pinholes is shown below. I would like…
Production from 2.28.08
Production this week yielded mixed results. We ran eight wafers through four different RTP temperatures with/without the susceptor. We wanted to test our theory that temperature non-uniformity inside the chamber was causing the morphology change across the wafer. This proved to not be the case! Wafers that were treated with and without susceptor showed the…
Modular assembly of the hToC: An adaptable protocol for interfacing a monolayer with a 3D culture
Introduction: This post presents a comprehensive protocol detailing an in vitro seeding and culturing method tailored for diverse cellular monolayer and tissue interfaces. These interfaces necessitate varying culturing conditions and extended timeframes, facilitated through modular device utilization. The methodology focuses on endothelial cells interfacing a three-dimensional (3D) tissue construct, demarcated by a porous membrane within…
