Conductance detection using granular films

Universal NanoSensor Technologies (UNS-Tech) develops and commercializes microfabricated conductivity detectors. In this MITACS project, UNS-Tech will partner with Prof. Cynthia to explore new detector architectures based on nano-particle and nano-shell films. The results will be analyzed and the findings will be published in scientific journals. The intern participating in this cluster will benefit from this internship by gaining tremendous knowledge of electronics-based detectors.

Fiber Optic Temperature Sensors: Phosphor Deposition and Processing Improvements

Photon Control R&D LTD is a Burnaby, British Columbia company that designs and manufactures a wide range of optical sensors & instruments to measure temperature, pressure, position, and flow in the semiconductor, oil and gas, power, life science, and manufacturing industries. The operating principle of many of their products is based on the optical response of phosphor materials and is well suited to applications in harsh environments.

Tailoring the Anisotropy of First-Row Transition Metal and Their Interactions

The proposed collaboration project between the Richeson and Journaux groups has a primary purpose of identifying new magnetic phenomena derived from common, inexpensive transition metals. The focus is on compounds containing cobalt and iron metal centers since these metals have larger than usual magnetic anisotropies. In order to design these compounds, specific chemical groups will be bonded to them in order to direct their behaviour. Prior research has shown promising candidates for this approach using bis(imino)pyridine, which will be a good starting points.

Synthesis and self-assembly of bipyrimidine decorated porphyrins

build molecular structures that exhibit specific properties such as rigidity, electric conductivity, or porosity. Building these structures without bricks and mortar is no easy task. Instead, we use synthetic chemistry to create new building blocks and take advantage of favorable interactions between these molecules to produce new assemblies. Porphyrins are naturally occurring molecules necessary for oxygenation of human blood and plant photosynthesis. By modifying the porphyrin scaffold we hope to be able to link many of these units together in one, two, and three dimensions.

Simultaneous analysis of amphetamine and derivatives in drug seizures and natural weight loss pills by capillary electrophoresis tandem mass spectrometry

This proposed research project is to develop and validate a method based on Capillary electrophoresis coupled with mass spectrometry to analyze amphetamine, methamphetamine, methylenedioxy-amphetamine, methylenedioxy-methamphetamine, and methylenedioxyethylamphetamine in real samples of drug seizures and natural weight loss pills, by first getting a basic understanding of CE-MS/MS technique and then applying it.

Determination of stress-induced modifications to vaccine proteins by mass spectrometry

The therapeutic effect of a vaccine depends on its chemical composition, and in particular the integrity of its protein components. Conditions under which a vaccine is manufactured and stored can damage the proteins it contains; however, since proteins are structurally complex and reactive, their degradation during routine handling is unpredictable. In the project described here, three candidate vaccine products will be subjected to models of manufacture and storage in order to induce chemical changes within them in a controlled manner.

Nonlinear Frequency Response Analysis for Fuel Cell Diagnostics

In order to enhance the capabilities of fuel cell test stations, a new tool for fuel cell diagnostics based on nonlinear frequency response analysis (NFRA) will be developed. NFRA applies a perturbation of the operating current and measures the voltage response of the cell. By varying the frequency of the perturbation, processes with different dynamics (i.e. fast or slow processes) are excited and can be probed individually. From this frequency response, the state of the cell can be determined.

NaLnF4 nanoparticles as high-sensitivity reagents for mass cytometry immunoassays

One of the goals of modern bioanalytical chemistry is the simultaneous (multiplexed) detection of multiple biomarkers in individual cells. Biomarkers are defined as characteristic proteins, genes, or small molecules that can be measured and evaluated as indicators of normal biological or pathological state of a cell. Mass cytometry is a recently developed technique developed by Fluidigm Inc to detect multiple biomarkers. Detecting fewer number of biomarker copies is essential because we can identify for instance a cancer causing biomarker at an early stage.

The application of Dried Blood Spot samples to Nutraceutical Metabolomics studies and related applications using LCMS based detection

The current approach for testing compounds of interest in blood such as drugs or nutrients involves drawing blood samples into vials that then require refrigeration prior to testing. Since transportation to remote laboratories is challenging, people need to go into medical labs to have their blood tested. This research will develop improved techniques that enable blood samples to be collected from a finger prick onto a specially designed card that eliminates biohazards and makes the sample stable at room temperature so that it could be mailed or sent by courier to a lab.
