Negative Data for Nanofluidic Transistors, Dielectic ‘Flowers’, and an Interesting Gold Filtering Behavior
I’ve been trying for a year now to make a nanofluidic transistor – a nanomembrane with a thin layer of metal coated in dielectric that allows for the dynamic modulation of the sieving characteristics of the chip. Beginning with the last 14 chips from wafer #1081, I coated them in ~3 nm of Ti and…
Pore formation process
ByJoe QiWe have suspected that those non-open pores in the TEM image of pnc-Si are pits in the silicon membrane for a long time. Last week, I SEMed a sample, oxide (30nm)/Si(25nm)/oxide(30nm) annealed at 800C for 1min, to verify the pits features. The first figure is a TEM image which the majority feature looks like non-open…
pH Variation of DMEM
(Transferred from old blog) Aim: Determine how quickly DMEM pH changes once removed from the incubator Methods and Materials: • non-sterile complete Dulbecco’s Modified Eagle’s Medium (DMEM) supplemented with 10% FBS • 6 and 24 well cell culture plates • 37 ºC 5% CO2 incubator 2 mL and 5 mL DMEM were placed in a…
Effect of Exosomes on Wound Healing Assay – 2
ByAslanHello Everyone, So Shannon and i have been working on studying the effect of exosomes in different conditions for wound healing assays and random migrations. This post is about one of our experiments (wound healing) to give you an update on our data and what we’re able to get with Henry’s matlab code. How the…
Focal Adhesion Formation on PDMS Substrates
ByAnaBackground Focal adhesions occur in 2D cell cultures as substrates apply large forces on cells. Previous experiments showed that focal adhesions formed on TCP and on non-porous SiO2 membranes but that less formed on 3.0µm-pore SiO2 porous membranes and even less on 0.5µm-pore SiO2 porous membranes. In other words, as area between pores decreased, formation…
