2018/19-2019/20 • $78,000 • PI
The need for analytical technologies that provide rapid, quantitative, and ultrasensitive detection of chemical compounds in environmental or biological samples is globally on the rise. Raman spectroscopy, with its inherent biochemical specificity, simplicity in sample preparation and...

Strategies for AC electrokinetic manipulation and detection of viruses in microfluidic environments

2013/14-2017/18 • $145,000 • PI
The inability of present-day diagnostic tools to provide early detection of pathogenic viruses (HIV-AIDS, H1N1, West Nile) does not allow prevention or early containment of an infection. Additionally, governments around the world, along with civilians and the military, are becoming increasingly...

Cost-effective and disposable microbatteries for point-of-care-testing and other microfluidic applications

2013/14-2016/17 • $100,000 • PI,CO
Microfluidics deals with fluids that are geometrically confined to a micro scale. Microfluidic devices provide a means for healthcare testing at the site of the patient; i.e. the so-called Point-of-Care Testing (POCT). Diagnostics that previously required several steps, highly skilled personnel...

Environmentally friendly and scalable production of multi-layered graphene from graphite

2016/17 • $24,900 • PI
Eagle Graphite Corporation (EGC) is a Canadian company that owns one of only two operating natural graphite mines and beneficiation plants in North America. As part of their mandate to develop graphite mines and production facilities to cover the needs of the Canadian graphite and graphene...

Graphene-based super-hydrophobic coatings

2015/16 • $25,000 • PI
Alcereco Inc. is interested in manufacturing super-hydrophobic coatings by taking advantage of a proprietary surface-conversion process that it has recently developed. Super-hydrophobic coatings exhibit poor water spreading characteristics, i.e., they cause water to bead up and form droplets...

Development of AC electrokinetics-based methodologies for nanoparticle assembly

2010/11-2012/13 • $84,000 • PI
The controlled manipulation and organization of colloidal particles (i.e., particles with size smaller than 1 micron stably suspended in a fluid) into one-, and multi-dimensional ordered structures represents the first step towards the fabrication of a large number of miniaturized products of...



An electrokinetics-assisted sensor for sensing a target material. The sensor may include a microstructure deflectable in response to added mass on its body. The sensor may also include one or more features on or near the microstructure designed to generate an electric field giving rise to one or more electrokinetic effects to drive material towards the microstructure, when an electrical signal is applied to the feature(s). Presence of the target material on the body of the microstructure may...
