Microfluidic Control of Adipose-Derived Stem Cell Growth and Positioning

Wadhawan N., Kalkat H., Ma X., Gajjeraman S., Nandagopal S., Hao N., Deng J., Xiang B., Zhang M., Tian G., Lin F., University of Manitoba, CA

Microfluidic devices provide powerful new tools for quantitative stem cell research owing to its advantages in cellular microenvironmental control and experiment throughput over conventional methods. Particularly, microfluidics is playing a growing role in studying stem [...]

Polypyrrole nanoionic composites for solid state electronics

Zhao J.H., Pillai R.G., Freund M.S., Thomson D.J., University of Manitoba, CA

In this report, a conjugated semiconducting polymer composite was designed to have a mobile charge carrier density that can be controlled through an electric field. An electrochemically deposited polypyrrole (PPy) composite between two gold electrodes [...]

Capacitance signatures for rapid detection of the polarity of the dielectrophoretic force on single yeast cells

Ferrier G.A., Romanuik S.F., Thomson D.J., Bridges G.E., Freeman M.R., University of Manitoba, CA

Previously, we demonstrated a system that can detect the presence of yeast cells using capacitance measurements from a cavity resonator. The resonator is coupled to a set of electrodes, which are aligned 90 degrees relative [...]

Microfluidic electromanipulation with capacitive detection for cell diagnostic applications

Ferrier G.A., Hladio A.N., Thomson D.J., Bridges G.E., Hedayatipoor M., Olson S., Freeman M., University of Manitoba, CA

We are proposing an all-electrical approach to mechanical cell diagnostics that uses a combination of electromanipulation for stimulus and capacitance for sensing. We have successfully used the capacitive sensor to detect the electrical trapping (using [...]
