Introduction We are designing a cell culture chamber insert to allow side-by-side co-culture of cells and ultimately triculture in the µSiM devices. Materials and Methods ALine devices assembly according to the “ALine Modular Device Assembly” instructions. 2-slot NPN membranes applied…

Monocyte Isolation via CD14+ Selection (Protocol)
Please see the attached .PDF file for a full monocyte isolation protocol. This is for isolating human monocytes from whole blood. Monocyte-Isolation-Protocol
Rotation Project Complete: Dialysis of cytochrome c across a commercial membrane
Dan Steiner Rotation Summary Abstract The purpose of this rotation project was to develop and test a clampable system for eventual use in scalable nanomembrane dialysis systems. The nanomembrane dialysis system will be miniaturized into a compact, wearable hemodialysis device that…
YAP/TAZ Staining on Membranes and Nonporous SiO2
As we’re uncovering more bits and pieces of data, we kept being lead to the idea that our membranes may be made out of SiO2 and have a modulus in the gigapascal range, but cells seem to perceive them as soft…
Cleaning MgF2 Nanomembranes after International Shipping
I had previously manufactured some freestanding MgF2 nanomembranes (50 nm MgF2, starting from Wafer Template 1174) for my work here in Nottingham. I shipped about 75 chips at the beginning of July in my 3d printed holders, however, they arrived with…
Nanomembranes+Microfluidic PETLs Integration
Our collaborator Fernando has made a really nifty way to make microfluidics work with lamination pouches. These flat pouches can be sealed together using a heat activated glue, which can be done consistently using a 15 for a 100-pack of 8.5″x12″…
MgF2 Cytocompatibility #4
Summary: I have some ok images (20x) of cells growing on MgF2. My controls still look poor. Something about the stain is causing the TCP + NPN controls to detach ahead of the MgF2 material, even if they aren’t fully dead…
New Alt. Membrane Release Recipe (Nitride RIE)
I have lost many chips during my MgF2 or Au or Pt process due to yield problems with my RIE. I have wondered if the problem was due to power spikes. I have observed that my most poorly yielding etch…
Wetting of Nanocavities using Isobaric Cooling
Summary and Instructional video The simplest way to get something wet is to allow water to condense on the surface of the something. In our case, we have a number of nanocavities (~ 0.1 femtoliters) with porous tents over them. The…
Bonding PDMS to PET films
PET is a very common material used in various cell culture applications. Unfortunately it’s chemical inertness makes it immune to plasma activation, and we can’t bond PDMS devices to PET. I am working with a PET films coated with Indium…
