This proposal requests financial support for conducting a market assessment study on a circuit-free technology capable of measuring the pH of solutions. The assessment aims to evaluate which applications represent the most promising market opportunity for technology based on referenced optical pH sensors. This proposal follows a proof of feasibility of a new sensing technology developed by Martel and coworkers, which is based on an innovative pH responsive probe comprised of metallic Single-Walled Carbon Nanotubes (SWCNTs) in contact with a platinum redox couple. This Pt-SWCNT sensors was shown to provide optical measurements of the pH in aqueous solutions across a broad range of values between 1 and 12 with a best accuracy of ±500 mpH unit. The technology demonstrates for the first time optical pH sensing analogous to a conventional pH sensor equipped with a built-in internal reference, with the added benefits of wireless and remote measurements across the full pH range. The potential applications include in situ monitoring of pH in an industrial reactor, food monitoring, in-vivo studies of metabolisms, etc. The study will define the addressable market of such electrodeless pH sensors for remote optical pH measurements and identify the significance of the competitive advantage that the technology could provide.
