Bioactivation of Titanium Surfaces by Femtosecond laser Processing

Tavangar A., Tan B., Venkatakrishnan K., Ryerson University, CA

In this study, we propose a novel yet simple method to generate titanium oxide 3-D nanofibrous structures on the titanium implants using femtosecond laser machining. The femtosecond laser pulses hit the titanium substrate and generate [...]

Nanoparticles co-encapsulating hVEGF and hAng-1 can induce mitotic and antiapoptotic effect on vascular endothelial cells

Khan A.A., Paul A., Abbasi S., Prakash S., McGill University, CA

This study demonstrates the combined effect of the angiogenic proteins, hVEGF and hAng-1, coencapsulated in human serum albumin (HSA) nanoparticles (NPs), towards human umbilical vein endothelial cells (HUVECs) and an evaluation of the potential application [...]

Indium Phosphide : Cadmium Free Quantum Dots for Cancer Imaging and Therapy

Chibli H., Carlini L., Park S., Dimitrijevic N., Nadeau J.L., McGill University, CA

We synthesised Indium phosphide (InP) quantum dots (QDs) with different shell layer. We demonstrate highly fluorescent labeling of cell lines after nonspecific endocytosis of the QD. With spin-trap electron paramagnetic resonance (EPR) spectroscopy and reporter [...]

Plasmonic nanostructure based biosensing

Patskovsky S., École Polytechnique de Montréal, CA

Plasmonics is quickly becoming a dominant technology in the fields of novel optical devices employing new experimental capabilities of subwavelength metallic nanostructures. In combination with modern nanofabrication technologies which allows preparation of numerous regular patterns [...]

Highly robust array of nanosensing platform for biosensing application

Stateikina I., Ng A., Chinnappan R., Ahmed M., Zourob M., INRS, CA

This work presents a simple method of combining macro connectors with pre-fabricated nanovire chips. This design offers a unique ease and rapidity of connecting the nanowires with the connectors without using imaging and external aid [...]

Smectic structure of Nano Crystalline Cellulose Established by Large-Scale Parallel Molecular Dynamic Simulations

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

Structural and optical properties of Nano Crystalline Cellulose (NCC) in liquid solutions and in solid films were investigated by large-scale parallel molecular dynamics (MD) simulation using empirical Coulombian interaction potentials. Our calculations give a good [...]

Rapid Fabrication of Nanofibrous Membranes inside microchannels using Femtosecond Laser Micromaching

Tavangar A., Tan B., Venkatakrishnan K., Ryerson University, CA

In this paper, we propose a single-step technique to develop membrane-based microfluidic channels using femtosecond laser micromachining. The proposed method fabricates both the nanoporous membrane and microfluidic channel in a single step under ambient condition. [...]

Octadecylphosphonic acid Langmuir-Blodgett films and their modification by hyperthermal hydrogen projectile

Dey R., The university of waterloo, CA

We report on surface modification with hyperthermal hydrogen induced cross-linking (HHIC) technology on uniform and well-ordered octadecylphosphonic acid (OPA) Langmuir-Blodgett (LB) films on several surfaces, and on surface characterizations of its properties. The hyperthermal hydrogen [...]

Photonic crystals with nanocelulose

Picard G., Simon D., Kadiri Y., Lebreux J.-D., Gozayel F., College Ahuntsic, CA

Nano Crystalline Cellulose (NCC) can be easily extracted from wood. This has been known for several decades (see for modern extraction method the reference 1). It was also demonstrated for decades that letting the dispersion [...]

Carbon-supported platinum and nickel nanoparticles for CO capture in hydrogen fuel cells

J. D. Durbin D., J. Fermin D., Plana D., J. D. Durbin D., J. Fermin D., Malardier-Jugroot C., Royal Military College of Canada, CA

Fuel cells are electrochemical cells that convert chemical energy into electrical energy with efficiencies up to 80%; they are a promising potential replacement for internal combustion engines in automobiles. However, carbon monoxide poisoning of the [...]
