BRIGE: The Design and Characterization of a Multifunctional Chemiresistor Sensor Array

多功能化学电阻传感器阵列的设计和表征“该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。”智力优势：本提案的目标是设计一个多功能化学电阻传感器阵列，该阵列集成了各种预先选择的功能化金纳米粒子和超灵敏静电计。这种设备的可用性将有利于医疗保健或药物诊断，因为这些领域必须快速收集和分析大量数据。所提出的传感器阵列的思想是在阵列的每一行中静电捕获不同的功能化纳米颗粒。金纳米粒子将被困在一个纳米隙中，这个纳米隙是由夹在氮化镓层之间的氮化铝量子阱形成的。提出的研究利用单电子器件与金纳米颗粒的使用，来展示多功能化学电阻传感器阵列。器件的特性将包括测量暴露于挥发性有机化合物时电流-电压曲线变化的幅度。长期目标是探索单分子检测的机制（即粒子电容或电荷的变化）。这项研究的成功将使基于纳米粒子传感器的单分子转移事件的基础研究成为可能。更广泛的影响：提出的研究促进了化学电阻传感器的使用，由于其简单廉价的制造方法和小尺寸（~nm尺度）而具有吸引力。将所提出的多功能传感器阵列引入社会，有助于医疗，食品和药品业务的进步。例如，这些设备可以很容易地在汽车工业中实施，在汽车工业中需要传感器来检测废气中的碳氢化合物或二氧化碳。此外，拟议的化学电阻传感器可以检测痕量爆炸物，这将是国家安全行业感兴趣的。为了培养一支广泛包容的科学和工程劳动力队伍，拟议的研究旨在促进学生的科学培训，同时扩大代表性不足群体的参与。这将通过一项新的教育计划来实现，该计划被称为NOLA moves（新奥尔良路易斯安那州通过科学教育研究的少数民族机会）。这个暑期项目将支持一所历史悠久的黑人学院和大学的学生参加伦斯勒的一流研究。此外，伦斯勒科学学院将建立一个独特的研究项目，以动员“未申报”的理科生。

BRIGE ECCS - 0927057The Design and Characterization of a Multifunctional Chemiresistor Sensor Array"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)."Intellectual Merit: The objective of this proposal is to design a multifunctional chemiresistor sensor array which integrates a variety of preselected functionalized gold nanoparticles and supersensitive electrometers. The availability of such a device will be beneficial in healthcare or drug diagnostics where large amounts of data must be quickly collected and analyzed. The idea of the proposed sensor array is to electrostatically trap a different functionalized nanoparticle in each row of the array. The gold nanoparticles will be trapped in a nanogap, which is formed by an aluminum nitride quantum well sandwiched between gallium nitride layers. The proposed research exploits the use of single electron devices with Au nanoparticles, to demonstrate a multifunctional chemiresistor sensor array. Characterization of the devices will include measurement of the magnitude by which the current-voltage curves are altered upon exposure to volatile organic compounds. The long term goal is to explore the mechanisms (i.e., change in particle capacitance or charge) responsible for single molecule detection. Success of the research will enable fundamental studies of single molecule transfer events in nanoparticle based sensors.Broader Impact: The proposed research promotes the use of chemiresistor sensors, which are attractive due to its simple and cheap fabrication methods and small size (~nm scale). Introducing the proposed multifunctional sensor array to society contributes to the advancement of medical, food and drug businesses. For example, these devices can easily be implemented in the automobile industry where sensors are needed to detect hydrocarbons or CO2 in exhaust gases. Also, the proposed chemiresistor sensors can enable the detection of trace explosives, which will be of interest to the nation's security industries. To cultivate a broadly inclusive science and engineering workforce, the proposed research is designed to promote scientific training of students while broadening the participation of underrepresented groups. This will be accomplished through a new educational program, called NOLA MOVERS (New Orleans Louisiana Minority Opportunities via Educational Research in Science). This summer program will be established to support students from a Historically Black College and University to participate in first class research at Rensselaer. Also, a unique research program will be established in Rensselaer's School of Science to mobilize "undeclared" science students.
