OUR WATER REVOLUTION

 

 

Much of our success in the work we do is a result of a lot of hard work, entrepreneurship, and dedication. We are committed to enhancing the safety of our waters and having a tangible impact on human lives, society, and the environment. Have a look at some of our latest and greatest achievements.

Published in Nature Communications - Selective Ion Sensing in Real Time

Real-time, high resolution, simultaneous measurement of multiple ionic species is challenging with existing chromatographic, spectrophotometric and potentiometric techniques. Potentiometric ion sensors exhibit limitations in both resolution and selectivity. We develop wafer scale graphene transistor technology for overcoming these limitations. Large area graphene is an ideal material for high resolution ion sensitive field effect transistors (ISFETs), while simultaneously enabling facile fabrication as compared to conventional semiconductors. We develop the ISFETs into an array and apply Nikolskii–Eisenman analysis to account for cross-sensitivity and thereby achieve high selectivity. We experimentally demonstrate real-time, simultaneous concentration measurement of different ions in an aquarium with remarkable resolution and accuracy. 

2019 William and Rhea Seath Award in Engineering Innovation - $28,000 AWARD

The William and Rhea Seath Awards (WRSAs) have been established to support innovative technological ideas and research in engineering. These Awards recognize outstanding students and professors, who have innovative technological ideas or research results with potential for commercialization.

We demonstrate large-area graphene based ion sensitive field effect transistors (ISFETs) with potassium ionophore sensing layers. Graphene ISFETs encapsulated with an ultra-thin hydrophobic layer, parylene C, improves ion sensing performance. We observer detection limits and resolutions orders of magnitude better than state-of-the-art. The sensors exhibit remarkable stability and reproducibility over a five-month period. The sensors have been tested in  a variety of specimens, including beverages and blood. The graphene ISFET design can be extended to sensing of other ionic species by substitution of alternative ionophores within the sensing membrane.

UltraSense Invited to LDE North America 2018

UltraSense was invited to the Lebanese Diaspora Energy - North America 2018 in Montreal, an event hosted by the Lebanese Ministry of Foreign Affairs and Emigrants for establishing connections and promoting new possibilities. At the LDE, we talked about our vision for revolutionizing water quality monitoring among highly influential members in the Canadian and Lebanese communities, including Ministers, Ambassadors, Members of Parliaments and CEOs.
