Development of high-performance electrochemical enzyme biosensors based on carbon nanotube complexes with conjugated polyelectrolytes

A simple and facile route for the construction of highly sensitive electrochemical enzyme biosensors has been proposed using carbon nanotube (CNT) complexes with a conducting poly(thiophene) polymer. Glucose oxidase was used as a model enzyme for the construction of the advanced biosensors. Glucose biosensors, exhibiting sensitivity higher than any biosensor based on CNTs and other […]

The travel behaviour of recent immigrants in the Greater Toronto Area

The proposed research will explore how diverse recent immigrant populations in the Greater Toronto Area (GTA) use the transportation system to meet their daily-life needs.  The objectives are to explore how these groups make use of surrounding urban environments, provide a description of the processes used to secure transportation and the barriers faced, and examine […]

Design of a novel magnetoencephalograph-compatible tracking system for monitoring speech-related orofacial events

Individuals with speech problems face difficulties such as anxiety, poor socialization and poor literacy. Key to effective intervention and therapy is a better understanding of the brain activity associated with speech. Magnetoencephalography (MEG) is a new brain-imaging technology that, for the first time, allows researchers to monitor the fast-changing brain activity involved with speech. The […]

Developing a prototype electrowetting on dielectric device to perform immunoassays

The goal of this project is to develop a prototype microfluidic device to rapidly determine whether a target protein is present in a sample. Applications of this device include genomic and proteomic research, pharmaceutical testing, and quality control for various industries, including food preparation. The prototype will make use of electrowetting on dielectric (EWOD) actuation, […]

Building Surfaces from Curve Sketches

In recent years 3D sketching has received considerable attention and a number of powerful tools (such as ILoveSketch) have been developed which can interpret strokes of a design artist as three-dimensional curves. Using these tools, the artist can create, in roughly the same time it takes him/her to draw a single 2D sketch, a loose […]

Mathematical Analysis of Partial Differential Equations Modeling Electrostatic MEMS

Microelectromechanical systems (MEMS) and nanoelectromechanical systems (NEMS), which combine electronics with miniature-size mechanical devices, are essential components of the modern technology. In order to provide accurate, controlled, and stable locomotion for such microdevices, researchers have proposed a variety of models, based upon thermal, biological, or electrostatic forces. There are many industries and manufacturers in Ontario […]

A study of free surface electrospinning to enhance and optimize the nanofibre production process

Free Surface Electrospinning (FSE) is a novel process capable of producing non-woven webs of continuous nanofibres with controlled morphology and size from polymer solutions with the application of high electric fields. This novel scheme which was based on a rotating cylinder-solution feeding system is capable of producing nanofibres at a reasonable rate with compared to […]

Cold laser ablation as a novel tool for biodiagnostic applications and biomarker discovery

We have developed a technology platform that allows us to obtain quantitative information regarding biomarkers much faster than currently possible, without the need to use expensive antibodies for detection. Our platform allows for simultaneous detection of many biomarkers at once. This reduces the time and the cost associated with biodiagnosis, and will directly contribute to […]

Pain-Free Steroid Hormone Extract Analysis Using Digital Microfluidics

Quantitative steroid hormone measurements are a mainstay in the field of clinical endocrinology, due to their effects in myriad processes from maturation to hormone-sensitive cancers. Conventional steroid hormone testing protocols require a venopunture blood draw (~5 mL) followed by a time consuming immunoassay (~2 hr) each time a single  hormone is tested. In response to […]

Pe-cursor reduction for improving signal integrity in high-speed data Communications

As data transmission rates increase, transmission quality over existing channels degrades. Advanced signal processing techniques to compensate for the mechanisms which degrade transmission quality are known. Simulations studies conducted at the data rates proposed for next generation data communication products show that pre-cursor inter-symbol interference (ISI) is becoming a significant contributor to degradation in transmission […]
