Development of a new conductive carbon ink for printed sensors for smart diapers

Urinary incontinence has been always a tedious and a distressing health problem, especially for elderly people in nursing home residents. To address this issue, an effective management system is highly required to enhance the quality care, prevent health issues, and reduce labor costs. This project is focusing to develop a flexible and wearable sensor based on carbon nanomaterials. The final product, in addition to the sensor, consists Wi-FI module and app.

Remediation of Contaminated Soil and Groundwater using Nanotechnologies - Year two

Contamination in soil and groundwater tends to be overlooked since their adverse impact does not appear exteriorly and instantaneously. However, the contaminants could potentially cause adverse impact on vegetation and human health by migrating off the contaminated site through groundwater flow, and also influence climate change through cycling of elements. Recently, demand for remediation of contaminated soil and groundwater has been raised due to increasing public awareness about environmental problems.

GaN Power Transistor Modelling and Experimental Verification

Crosslight Software Inc. is a leading provider of technology CAD (TCAD) tools for the design and simulation of semiconductor devices. They are specialized in innovative III-V compound materials which are considered as the next generation materials for power semiconductor devices. Crosslight has on-going activities in developing accurate simulation models for gallium nitride (GaN) material and devices. In particular, this is critical for the design of GaN based power transistors.

Assessment of DNA Ministring technology in cell transfection and the treatment of Colorectal Cancer (CRC)

Despite the power of gene therapy, its successful application to medicine has been diminished due to: (i) high toxicities and potentially fatal adverse effects; (ii) poor transgene expression in target cells; and (iii) extensive vector degradation. While viral vectors greatly improve efficiency, they sometimes lead to cancers due to chromosomal integration and may suffer from a lack of desired tissue selectivity. In contrast, nonviral systems have proven safer, but less efficient.

Silicon Quantum Dot Trace Explosive Sensor

Development and testing of a trace explosive sensor based on silicon nanomaterials or quantum dots. The project will involve interaction and pilot testing with the RCMP and Transport Canada. The success of the project will enable Applied Quantum Materials to introduce a new product into the security marketplace and form a platform technology for the development of drug and chemical agent detection.

Enhancement of Cement Properties by Means of In Situ Prepared Nanoparticles

Cement is a vital material in our modern society. It is the only thing that humans consume more of, by volume, than water. Conventional cement-based materials are usually brittle, have low tensile strength and exhibit bulk shrinkage. With the recent advancements in nanotechnology, many researchers investigated the addition of nanoparticles to the cement mix to enhance its workability and mechanical properties. In fact, nanoparticles were found to increase compressive and tensile strengths and decrease porosity and permeability of the cement.

Low cost micro dispenser for general analytical or synthetic applications

The micro-dispenser serves to accurately and precisely dispense a variety of fluids in droplets with volumes in the microliter range. The micro dispensing is quite valuable as it reduces the required volume of reagents and subsequently reducing cost. Here we propose a novel micro dispensing technology based on electrowetting on dielectric (EWOD) digital microfluidic (DMF) technique.

A nanostructured surface for ultrasensitive detection of illicit drugs in oral fluids

Drug-impaired driving is a growing threat to the safety of road users in North America and Europe. In Ontario, over 10% of the total road fatalities involved drugs and 36% of fatally injured drivers had drugs in their system while driving. Point-of-care testing (POCT) devices, akin to the Approved Screening Device (ASD) test for alcohol, are time- and cost-efficient tools for providing enforceable means of determining impairment by drugs in drivers at the roadside.

Atomic Layer Deposition Tool – Testing and Process Development - Year two

Currently, no Canadian-based companies are involved in the manufacturing of state-of-the-art research tools for atomic layer deposition (ALD). Angstrom Engineering is a leading manufacturer of similar technologies – physical vapour deposition and chemical vapour deposition – and have identified an opportunity to produce the first ALD research tool manufactured entirely in Canada. ALD is a vapour phase technique that offers sequential, self-limiting surface reactions to deposit thin films with exceptional control over thickness and composition, as well as conformality and uniformity.

Nano-varnish with integrated biomineralizable and antibacterial activity against dental caries

Dental caries is a major health hazard in the general population worldwide. Fluoride-based formulations are conventionally used to resolve this problem but they present certain important disadvantages, which has been overlooked. Here we propose to develop and characterize a non-fluoride based dental varnish using natural product conjugated nanoparticles that holds the potential of inhibiting bacterial plaque formation and repair early damage on tooth surface. The potential long-term benefits of this product are extensive and include prevention of dental caries and improved quality of life.
