Phosphorus (P) is an essential element that forms the basis for all life on earth. Phosphorus plays a central role in biogeochemical cycles that broadly impact global biological productivity, food resources, energy generation, and climate. Understanding the complex interrelationships between critical food, energy, and water resources and addressing phosphorus demand, pollution, and recovery are some of the greatest scientific challenges for a sustainable future. At the root of these problems is the inability to measure phosphorus directly when and where one would like and to do so in a cost-effective manner. This technology gap precludes the ability to close the “phosphorus cycle” at regional, national, and global scales. This Growing Convergence Research project will overcome fundamental science, engineering, and prototyping challenges to enable portable, low-cost, robust, and selective sensors for phosphorus that address these critical and unmet needs. This project brings together researchers with expertise spanning supramolecular and inorganic chemistry, polymer science, soft-matter electronics, electrical engineering, and environmental and marine science. Convergent scientific, technological, and engineering advances will coalesce to realize new paradigms for control at the chemical, supramolecular, transduction, and device levels that will ultimately serve as the basis for ushering in a completely new generation of sensors for phosphorus. These sensors will satisfy the functional and economic requirements needed to provide pragmatic solutions for capturing the complexity of how phosphorus exists in space and time within agricultural landscapes, waterways, and ecosystems. Engagements with stakeholders, industrial partners, and government agencies will guide efforts towards additional applications, commercialization, and other societally relevant sensing challenges.This convergent research program will integrate basic science and engineering approaches together and combine significant intellectual and technical overlap between traditionally disparate disciplines to address long-standing challenges that have limited the development of phosphorus sensing technologies. Specific objectives of the program are to: (1) design, develop and understand how molecular recognition elements (“receptors”) selectively bind phosphorus in the form of inorganic and organic phosphate compounds, (2) tailor receptor-analyte-semiconductor interactions and investigate how they specifically transduce the phosphate-binding events into a sensitive signal; (3) integrate these chemistries within low-cost electronic devices; (4) engineer sensors that enable sensitive quantification in complex environments for managing the phosphorus cycle including agricultural runoff, wastewater, and fresh, brackish, estuarine, and marine environments; (5) communicate chemical phosphate detection to electronic platforms to digitize and relay this data; and (6) develop prototypes for field use and demonstrations. This holistic approach will produce field-deployable technologies for phosphorus that are low-cost, operate in real-time, and directly interface with commercial platforms broadly utilized within agricultural, environmental, and marine monitoring.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

磷（P）是构成地球上所有生命的基础的重要元素。磷在生物地球化学周期中起着核心作用，从而广泛影响全球生物学生产力，食物资源，能源产生和气候。了解关键食品，能源和水资源之间的复杂相互关系以及解决磷的需求，污染和恢复是可持续未来的一些最大科学挑战。这些问题的根源是无法直接以具有成本效益的方式直接测量何时何地并在哪里进行磷。这种技术差距排除了在区域，国家和全球量表上关闭“磷周期”的能力。这个不断增长的研究项目将克服基础科学，工程和原型挑战，以使磷的便携式，低成本，健壮和选择性传感器能够满足这些关键和未满足的需求。该项目汇集了具有跨越超分子和无机化学，聚合物科学，软性电子，电气工程以及环境和海洋科学的专业知识的研究人员。收敛的科学，技术和工程进步将合并，以实现化学，超分子，转导和设备水平的新范式，最终将成为迎接全新一代磷传感器的基础。传感器将满足提供务实解决方案所需的功能和经济要求，以捕获农业景观，水道和生态系统中磷的复杂性。与利益相关者，工业合作伙伴和政府机构的参与将指导为其他应用，商业化和其他与社会相关的感应挑战的努力。该收敛研究计划将将基础科学和工程方法整合在一起，并将重大的知识和技术重叠融合在一起，并在传统上不同的训练之间进行跨性别的挑战，以解决长期以来的挑战，以限制磷sissecties技术的发展。该程序的特定对象是：（1）设计，开发和理解分子识别元件（“受体”）如何以无机和有机磷酸盐化合物的形式选择性地结合磷，（2）量身定制的受体 - 动脉粥样硬化症状相互作用并调查如何专门将磷酸盐结合的事件转化为磷酸盐的敏感事件； （3）将这些化学家整合在低成本电子设备中； （4）在复杂环境中启用敏感定量的工程师传感器，以管理磷循环，包括农业径流，废水，新鲜，咸淡的，咸味，河口和海洋环境； （5）将化学磷酸盐检测传达到电子平台上，以数字化和中继此数据； （6）开发用于现场使用和演示的原型。这种整体方法将为磷的野外技术生产，这些技术是低成本，实时运行的，并直接与在农业，环境和海洋监测中广泛使用的商业平台直接接触。这奖反映了NSF的法定任务，并认为通过基金会的知识优点和广泛的criperia criperia criperia criperia criperia criperia criperia criperia criperia the Issed the the奖励，并被认为是宝贵的支持。
