项目摘要

Community-engaged soil sensing is essential for confronting the challenge of toxic pollution—specifically arsenic and per- and poly-fluoroalkyl substances (PFAS)—in human environments. This project uses bacteria as sensors of soil contaminants, ultimately leading to the production of paper-based “test strips” that generate a quantitative reading of contaminant concentrations in soil. Such biosensors can support basic science as well as community-engaged investigations of exposure pathways. The project uses a “responsible research and innovation” (RRI) framework, which means including stakeholders—particularly citizen scientists—in the research process to enhance capacity to anticipate consequences of different sensor designs, reflect on the researchers’ assumptions, and respond to stakeholder needs and values.This work aims to create a biohybrid device that can exploit and tune the strengths of both electronic and biological sensing with the invention of a dynamic bioelectronic interface. By separating the actuation and sensing stages with different bacteria, a transfer function between signal gain and system stability can be engineered and customized toward community sensing needs. Development of the device involves pursuit of four interdependent aims: 1) engaging stakeholders through citizen science and an advisory board in order to inform research priorities and approaches, 2) using two different bacteria that function as the sensing front end (E.coli) and electroactive backend (S. oneidensis) to produce arsenic detection at detection levels comparable to current standards, 3) experimentation with electroactive bacteria species (P. aeroginosa) to advance toward a PFAS biosensor, and 4) iterative development of a paper-based sensor design that is suitable for community-based environmental monitoring.This award was made through the "Signals in the Soil (SitS)" solicitation, a collaborative partnership between the National Science Foundation and the United States Department of Agriculture National Institute of Food and Agriculture (USDA NIFA).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.
社区参与的土壤遥感对于应对人类环境中有毒污染的挑战至关重要,特别是砷和全氟烷基和多氟烷基物质。该项目使用细菌作为土壤污染物的传感器,最终生产出基于纸张的“测试条”,可以定量读取土壤中的污染物浓度。这种生物传感器可以支持基础科学以及社区参与的接触途径调查。该项目采用“负责任的研究与创新”(RRI)框架,这意味着在研究过程中包括利益相关者,特别是公民科学家,以提高预测不同传感器设计后果的能力,反思研究人员的假设,并回应利益相关者的需求和价值观。这项工作旨在创造一种生物混合装置,通过发明动态生物电子接口,可以利用和调整电子和生物传感的优势。通过分离不同细菌的驱动和传感阶段,可以设计和定制信号增益和系统稳定性之间的传递函数,以满足社区传感需求。该设备的开发涉及四个相互依存的目标:1)通过公民科学和顾问委员会吸引利益相关者,以便为研究重点和方法提供信息;2)使用两种不同的细菌作为传感前端(大肠杆菌)和电活性后端(S. oneidensis),以产生与当前标准相当的检测水平的砷检测;3)对电活性细菌物种(P. aeroginosa)进行实验,以推进PFAS生物传感器。4)迭代开发适合社区环境监测的基于纸张的传感器设计。该奖项是通过“土壤信号”征集活动获得的,该征集活动是美国国家科学基金会和美国农业部国家粮食和农业研究所(USDA NIFA)之间的合作伙伴关系。该奖项反映了美国国家科学基金会的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
