This PFI: AIR Technology Translation project focuses on translating a patented nanoparticle-structured sensor technology needed to enhance the performance of air-quality chemical sensors. The sensor technology is important because it will have a broad impact to human health in terms of providing a method for the general population to measure air-contamination indicator volatile organic compounds (VOCs) levels and associated risks at home and in the environment. This project provides a large-scale and green route toward the low-cost synthesis of nanoparticles as printable nanomaterials that are used for manufacturing the sensors. It provides the advantage of lower cost manufacturing of the sensing nanomaterials in comparison with existing methods. Existing methods are mostly based on laboratory small quantity synthesis involving large amount of organic solvents, which not only adds a high cost for the manufacturing along with toxic wastes to the environment, but also diminish the viability of commercial scale manufacturing of the nanoparticles. The proposed nanoparticle-structured air-quality sensors will have several unique features such as tunable sensing structure and increased sensor stability, and are anticipated to enable high sensitivity, high selectivity, and low detection limit. This project addresses an important technology gap, as it translates from research discovery toward commercial application, between low-cost sensor manufacturing and scalable nanomaterials preparation by establishing a large-scale and green synthesis route for manufacturing copper-gold alloy nanoparticles as printable micorelectrodes and sensitive scaffolds. The proposed approach to synthesizing the alloy nanoparticles of different compositions by controlling aggregative nucleation and aggregative growth in aqueous solutions of highly-concentrated metal precursors will be tested. If successful, this will reduce the cost of the nanomaterials and create a green pathway that eliminates the use of large amounts of organic solvents as used in most of the existing synthesis protocols. This synthesis scale up features a number of unique attributes, including tunable surface composition compatible to gold-based surface chemistry needed for the sensing film structure, increased stability in comparison with pure copper nanoparticles, and lower cost of the nanoparticles in comparison with pure gold nanoparticles without sacrificing the desired performance. The combination of low-cost manufacturing, high sensitivity, and multiplexing capability of the sensors for detecting multiple VOCs is expected to be competitive in the sensor market in comparison with existing sensor products in the market manufactured by traditional microfabrication processes. Personnel involved in this project, including two graduate and two undergraduate student researchers, will receive training in terms of entrepreneurship and technology translation experiences through active collaborations with industrial partners towards commercialization of the technology in the sensor market for environmental monitoring. The project engages several industrial partners who have entrepreneurship experiences and are interested in licensing the nanoparticle and sensor technologies to test and evaluate the nanomaterials and sensor performances in this technology translation effort from research discovery toward commercial reality.

该PFI：AIR技术翻译项目的重点是翻译一项专利纳米结构传感器技术，以提高空气质量化学传感器的性能。 传感器技术很重要，因为它将对人类健康产生广泛的影响，为普通人群提供一种方法来测量空气污染指标挥发性有机化合物（VOC）水平以及家庭和环境中的相关风险。 该项目提供了一个大规模的和绿色的路线，以低成本合成的纳米粒子作为可打印的纳米材料，用于制造传感器。 与现有方法相比，它提供了传感纳米材料的低成本制造的优点。现有的方法大多基于实验室少量合成，涉及大量的有机溶剂，这不仅增加了制造的高成本，沿着有毒废物到环境中，而且降低了纳米颗粒的商业规模制造的可行性。 所提出的纳米颗粒结构的空气质量传感器将具有几个独特的功能，如可调的传感结构和增加的传感器稳定性，并预计能够实现高灵敏度，高选择性和低检测限。该项目解决了一个重要的技术差距，因为它从研究发现转化为商业应用，低成本的传感器制造和可扩展的纳米材料制备之间，通过建立一个大规模的和绿色合成路线制造铜金合金纳米粒子作为可打印的微电极和敏感的支架。 将测试所提出的通过控制高浓度金属前体的水溶液中的聚集成核和聚集生长来合成不同组成的合金纳米颗粒的方法。如果成功的话，这将降低纳米材料的成本，并创造一种绿色途径，消除了在大多数现有合成方案中使用的大量有机溶剂。 这种合成放大具有许多独特的属性，包括与感测膜结构所需的基于金的表面化学相容的可调表面组成，与纯铜纳米颗粒相比增加的稳定性，以及与纯金纳米颗粒相比纳米颗粒的较低成本，而不牺牲所需的性能。 与市场上现有的通过传统微制造工艺制造的传感器产品相比，用于检测多种VOC的传感器的低成本制造、高灵敏度和多路复用能力的组合预计在传感器市场上具有竞争力。 参与该项目的人员，包括两名研究生和两名本科生研究人员，将通过与工业合作伙伴的积极合作，在环境监测传感器市场的技术商业化方面接受创业和技术翻译经验方面的培训。 该项目吸引了几个有创业经验的工业合作伙伴，他们有兴趣授权纳米颗粒和传感器技术，以测试和评估从研究发现到商业现实的技术转化工作中的纳米材料和传感器性能。
