项目摘要

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.

该提案要求提供财政支持，以便对能够测量溶液酸碱度的无电路技术进行市场评估研究。该评估旨在评估哪些应用代表了基于参考光学pH传感器的技术最有前途的市场机会。这项建议是在Martel及其同事开发的一种新的传感技术的可行性得到证明之后提出的，该技术基于一种创新的pH响应探头，该探头由金属单壁碳纳米管(SWCNTs)与铂氧化还原对接触组成。这种铂碳纳米管传感器可以在1到12的宽值范围内对水溶液中的pH值进行光学测量，最佳精度为±500英里/小时。该技术首次展示了类似于配备内置内部基准的传统pH传感器的光学pH传感，并增加了在整个pH范围内进行无线和远程测量的好处。潜在的应用包括工业反应堆中pH的现场监测、食品监测、体内代谢研究等。这项研究将确定用于远程光学pH测量的这种无电极pH传感器的可寻址市场，并确定该技术所能提供的竞争优势的重要性。
