NER: Effect of Morphology of Pd & NiFe Nanowires on Sensor Response

本研究的目的是通过实验了解在不同条件下电沉积的Pd和NiFe一维纳米线的形貌和结构变化对其功能的影响。重点将放在纳米线的形态、尺寸和形成周期对传感器性能、灵敏度和可逆性的影响。将研究改变以下参数的影响：a)改变电镀参数的影响；b)不同模板（石墨、聚碳酸酯、氧化铝和多孔硅）的影响。本提案的研究目标是量化纳米颗粒/线（Pd/NiFe）形态在传感/分离中的作用和重要性，通过整合和评估（a)弯曲板波声传感器（FPW）上的Pd纳米线用于近实时检测气体，以及b） NiFe在细胞操作/分离实验中的磁性。本提案的研究成果将促进对使用纳米线作为传感/分离元件的基本理解。研究目标的成功完成将对开发现场可部署的实时基于纳米粒子/线的气体/碳氢化合物探测声传感器以及在新兴的纳米生物磁学领域中整合生物学和纳米技术产生深远的影响。与学术界、工业界和医疗中心的各种团体的现有合作将大大促进拟议研究的成功。教育计划包括两个主要部分：课程发展和推广：(a)通过纳入研究成果，改进目前在南佛罗里达大学教授的研究生水平的跨学科化学/生物传感器和微加工课程。这门新的跨学科课程部分是为USF的IGERT项目开发的，并大量借鉴了pi正在进行的研究。(b)目前与海洋科学学院和圣彼得堡学院的联系将得到加强。PI将与USF招聘和保留主任、圣彼得堡初级学院、希尔斯堡和皮内拉斯县教育系统合作，开发技术信息模块，为社区大学的教师提供沉浸式培训体验。智力优势：拟议的研究将不同研究领域（纳米结构，气体传感和生物磁学）的发展整合在一个新的方法中，这将促进从理解到传感的各个领域的知识和理解。该研究将为不同环境下的定量诊断提供依据。这是跨领域的重大进步。更广泛的影响：这项研究将培养学生在新兴的跨学科领域（电气，化学工程和物理）。这项研究以本科生的早期工作为基础，并将继续有本科生和代表性不足的群体（少数民族、妇女）的参与。这项研究的结果将通过纳入PI制定的课程和单元、示范和外联的方式广泛传播。

The goal of this research is to experimentally understand the effect of change in morphology and structure of one-dimensional nanowires of Pd and NiFe electrodeposited under different conditions on their function. The focus will be on correlating the effect of morphology, size and formation cycle of nanowires to sensor performance, sensitivity and reversibility. The effect of changing the following parameters will be studied a) effect of changing the plating parameters and, b) effect of different templates (graphite, polycarbonate, alumina and porous silicon). The research objectives of this proposal are to quantify the role and importance of nanoparticle/wire (Pd/NiFe) morphology in sensing/separation, by integrating and evaluating (a) the Pd nanowires on flexural Plate Wave Acoustic Sensor (FPW) for near-real time detection of gases, and, b) the magnetic properties of NiFe in cell manipulation/separation experiments. Research outcomes of this proposal would facilitate the fundamental understanding of using nanowires as sensing/separating elements. Successful accomplishment of the research objectives will have far reaching implications in development of field deployable real-time nanoparticle/wire based acoustic sensors for gas/hydrocarbon detection and in integration of biology and nanotechnology in the emerging field of nano bio-magnetics. The existing collaborations with various groups in academia, industry and medical centers will greatly enhance the success of the proposed research. The educational plan consists of two major parts: Course development and Outreach: (a) Improve the graduate-level interdisciplinary Chemical/Biological Sensors and Microfabrication course currently taught at University of South Florida, through incorporation of research results. This new interdisciplinary course has been developed in-part for the IGERT program at USF and draws heavily from the PIs ongoing research. (b) Current outreach extending to the College of Marine Science and St. Petersburg College will be strengthened. In collaboration with Director of Recruitment and Retention USF, St. Petersburg Junior College, Hillsborough and Pinellas County Education System, PI will develop technology information modules for immersive training experience for teachers in community colleges. Intellectual Merit: Proposed research integrates developments in different research areas (nanostructures, gas sensing and bio-magnetics) in a novel approach that will advance the knowledge and understanding in diverse fields, from understanding to sensing. The research will provide a basis for quantitative diagnosis in diverse environments. This is a major advance across fields. Broader Impact: This research will train students in emerging cross-disciplinary areas (Electrical, Chemical Engineering and Physics). The research is based upon early work of undergraduate student and will have continued participation of undergraduate students and underrepresented groups (minority, women). The results of the research will be widely disseminated through inclusion in courses and modules developed by PI, demonstrations and outreach.
