智力优势：拟议的职业研究的主要目标是通过微电子学和电化学的联姻实现纳米电化学系统，以实现低成本，高通量的台式纳米纤维。PI提出了一个高度非常规但强大的候选人实现这样的纳米电化学设备？自上而下制造的硅CMOS（互补金属氧化物半导体）管芯作为受控纳米制造的功能衬底。这种新的范式将CMOS技术的作用扩展到传统的计算、信号处理和通信领域之外，转向定向纳米组装和纳米制造。拟议的研究将开发两种方法：（1）用于纳米组装的CMOS：电场操纵和组装已经合成的纳米结构;（2）用于纳米纤维的CMOS：直接在CMOS上控制不同类型纳米线的电化学生长。内置的集成电路将促进组装和生长的实时反馈控制，并可重复使用作为传感的前端电路。该研究为在同一硅片上异质集成多种纳米材料提供了直接途径。作为概念验证，PI计划实施一种用于生物分析的纳米电化学传感器，主要用于检测神经递质，并对实际样品中的痕量重金属离子进行环境传感。更广泛的影响：该研究如果成功，将通过在化学和生物传感、高速电子以及能源产生和存储设备领域的创新和产品开发产生巨大的经济和社会影响。PI将实施四项关键举措，作为综合教育和推广计划的一部分：（一）本科课程中基于项目的学习举措;（二）自下而上的纳米制造研究生课程;（三）本科生跨学科研究经验;（四）面向公众的网络模块。少数民族和代表不足群体a的参与计划包括：㈠为塔夫茨大学和西蒙斯学院的女学生提供暑期和学期的研究机会，一个全女性的本科院校（ii）通过塔夫茨大学STEM多样性中心为代表性不足的群体提供暑期实习机会，以及（iii）K-12和社区外展，通过学生教师辅导方案和研讨会在当地高中在梅德福和马尔登地区。

Intellectual Merits: The main objective of the proposed career research is the realization of nanoelectrochemical systems through a marriage of microelectronics and electrochemistry for low-cost, high-throughput bench-top nanofabrication. The PI proposes a highly unconventional yet powerful candidate to realize such nanoelectrochemical devices ? that of top-down fabricated silicon CMOS (Complementary Metal Oxide Semiconductor) die as functional substrate for controlled nanofabrication. This new paradigm extends the role of CMOS technology beyond conventional areas of computation, signal processing and communication towards directed nanoassembly and nanofabrication. The proposed research will develop two approaches: (1) CMOS for Nanoassembly: Electric field manipulation and assembly of already synthesized nanostructures and (2) CMOS for Nanofabrication: Controlled electrochemical growth of different types of nanowires directly on CMOS. Built-in integrated circuits will facilitate real-time feedback control for assembly and growth, and can be reused as front-end circuits for sensing. The research provides a direct path for heterogeneous integration of multiple nanomaterials on same silicon chip. As a proof of concept, the PI plans to implement a nanoelectrochemical sensor for bioanalysis, primarily detection of neurotransmitters, and environmental sensing of trace heavy metal ions in actual samples.Broader impacts: The research, if successful, will have tremendous economic and societal impact through innovation and product development in areas of chemical and biological sensing, high-speed electronics, and devices for energy generation and storage. The PI will implement four key initiatives as part of the integrated education and outreach plan: (i) Project-based learning initiatives in undergraduate courses (ii) Graduate level course on Bottom-up nanomanufacturing, (iii) Interdisciplinary research experience for undergraduates, and (iv) Web based modules for public audience. Plans for participation of minorities and under-represented groupa include: (i) Summer and semester long research opportunities for women students from Tufts University and Simmons College, an all-women undergraduate institution (ii) Summer internship opportunities for under-represented groups advertised through the Center for STEM Diversity at Tufts University and (iii) K-12 and community outreach through student teacher mentorship programs and seminars at local high-schools in the Medford and Malden areas.
