Numerical Modeling of Microdrop Motion on Digital Microfluidic Multiplexer

Ahmadi A., Najjaran H., Holzman J., Hoorfar M., University of British Columbia, CA

This paper introduces a computationally efficient numerical modeling approach for microdroplet motion on an innovative Digital Microfluidic Multiplexer structure which enables the pilot synthesis and study of nanoparticles. This structure offers an enhanced level of [...]

A capillary effect based microfluidic system for high throughput screening of yeast cells

Mirzaei M., Juncker D., McGill University, CA

Microfluidic systems have been developed and used for high throughput cell-based assays successfully. However, these systems require complicated peripherals and a computer to control the flow, which limits their adoption by biologists. Here, we propose [...]

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 [...]

Multi-functional Wearable Device for Heart Health and Possition Assesment

Kaminska B., Simon Fraser University, CA

In this paper we introduce a wearable device combining physiological monitoring and person’s position assessment. An accelerometer is used as a multi-functional sensor for a position and heart mechanical performance measurements, known as mechanocardiography (MCG). [...]

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 [...]

Engineering of bacteriophages displaying affinity tags on its head for biosensor applications

Tolba M., Brovko L.Y., Griffiths M.W., University of Guelph, CA

A method was developed for the introduction of affinity tags onto bacteriophage heads using a phage display technique. It was shown that T4 bacteriophage carrying a biotin-binding polypeptide (Biotin Carboxyl Carrier Protein, BCCP, from acetyl-CoA [...]

Multifunctional nanoparticle platforms for pathogen diagnostic applications

Kell A.J., Paquet C., Simard B., National Research Council, CA

Infectious diseases and bioterrorism are of tremendous global concern, and our group is interested in developing superparamagnetic nanoparticle platforms that can aid in the magnetic extraction/concentration and detection of harmful pathogens. This has led to [...]

Effects-Based Risk Assessment of Emerging and Existing Nanomaterials

Chan-Remillard S., Kapustka L., Goudey S., Golder Associates Ltd. & HydroQual Laboratories Ltd., CA

Nanotechnology has been compared to the industrial revolution in its scope of applications and ability to dramatically transform new and existing technologies. Nanotechnology is a quickly emerging field where the toxicological effects on human and [...]

Nano cellulose crystallites: optical, photonic and electro-magnetic properties

Simon D., Kadiri Y., Picard G., Ahuntsic College, CA

(NCC) are tubes, about 200 nm long and 20 nm in diameter. This is a natural product, found in wood. It is separated by paper mills from long fibers, and rejected in mass volumes. In [...]

Synthesis of Nanopowders and Their Production at the Industrial Scale Using the Inductively-Coupled Plasma Technology

Dolbec R., Bolduc M., Fan X., Guo J., Jurewicz J., Xue S., Boulos M., Tekna Plasma Systems Inc., CA

The increasing demand for nanopowders (particles size
