Conformational analysis of alternating copolymers and their association into nanoarchitectures

Chan A.S.W., Groves M., Malardier-Jugroot C., Royal Military College of Canada, CA

Our research focuses on the characterization of the association and the properties in aqueous solution of nano-structures, particularly on nanotubes composed of amphiphilic alternating copolymers. These copolymers constitute a pH sensitive hydrophilic group (maleic anhydride) [...]

12 Billion Dollars Annually Expended on Throw away Filters- There is a new technology alternative to this wasteful practice

Bromley D., Enprotec, CA

In a world that is focussed at finding methods to use less energy or alternatives to existing energy driven products, one obvious change that is essential is the reduced use of disposable products. Specifically this [...]

Identification of Dynamic Structural Domains in Proteins, Analysis of Local Bond Flexibility,and Application for Interpretation of NMR Experiments

Stepanova M., National Institute for Nanotechnology, CA

A novel theoretical methodology is introduced to cidentify dynamic structural domains and analyze local flexibility in proteins. The methodology employs a multiscale approach combining identification of essential collective coordinates based on the covariance analysis of [...]

SERS Gold Nanoparticles for Cancer Surface Marker Detection

Nguyen C.T., Nguyen J., Nguyen C.T., Nguyen J., Rutledge S., Wang C., Walker G.C., University of Toronto, CA

Surface Enhanced Raman Scattering (SERS) gold nanoparticles may provide novel optical tags for cellular analysis. Currently, cell markers are mostly assessed by fluorescence labeling using flow cytometry. However, fluorescence dyes are usually limited to 4-5 [...]

Monitoring of the major blood vessels supplying head and brain (carotid arteries) contactlessly

Kaminska B., Simon Fraser University, CA

An apparatus for measuring Carotid Arteries movement without physically connecting electrodes or other sensors to the body was developed. The measurement system was implemented to simultaneously monitor the Carotid Arteries and ECG in order to [...]

Biochip for minimally invasive blood glucose monitoring

Zhang P., Ahmadi M.M., Jullien G.A., University of Calgary, CA

The most common techniques for blood glucose sensing are based on enzymatic glucose oxidation techniques because of being highly sensitive and specific to the glucose. But, the techniques need oxygen environment and the measurement accuracy [...]

A Novel Virtual Button User Interface for Determining the Characteristics of an Impulse Input Based on MEMS Inertial Sensors

Zwart A., Effa D., Nieva P., Lancaster-Larocque S., University of Waterloo, CA

This paper introduces a novel application of MEMS accelerometer in consumer electronics device for a ‘Virtual Button’ Technology. MEMS based accelerometers is designed in order to measure low-g acceleration to sense tapping motion on the [...]
