美国国家科学基金会-化学与运输系统部粒子与多相过程项目（1415）摘要申请号：0644789首席研究员：Kretzschmar， ilona单位：纽约市立大学申请题目：职业：用于分层自组装三维结构的独特功能化纳米粒子智力优势：本研究中提出的t型结构的合成可以作为一个有趣的等离子体开关模型系统。颗粒表面的位点特异性修饰，即贴片颗粒，以及随后的分子定向组装，通过为结合能、颗粒浓度和贴片大小的选择提供指导，推进了自组装领域。t型结构装配作为一个模型系统，用于实现分支结构，其中包含对三维装配至关重要的元素。此外，斑块状颗粒还可以作为表面活性剂、传感器和颗粒探针，以促进对胶体悬浮液和乳液稳定的理解。更广泛的影响：CCNY是一所公认的少数族裔服务机构，为西班牙裔（36%），非洲裔（30%），亚裔（23%）和白人（21%）学生提供多元化的本科学生群体。学生将受益于分子定向粒子组装领域的积极研究。IREU项目的组织为CCNY本科生提供了接触国际水平研究的机会。此外，建议的个人指导将为女性和少数民族学生在职业生涯早期提供一个指导网络。与路易斯-斯托克斯少数民族参与联盟（LSAMP）的合作将引导来自代表性不足群体的学生进入该项目。未来的记者、作家和制作人接触纳米技术可能会对我们这个以媒体为导向的社会产生强烈的影响，并将有助于提高非技术作家对纳米技术潜在应用的认识，以及公众舆论对该领域发展的影响。

National Science Foundation - Division of Chemical &Transport Systems Particulate & Multiphase Processes Program (1415)ABSTRACTProposal Number: 0644789Principal Investigator: Kretzschmar, IlonaAffiliation: CUNY City CollegeProposal Title: CAREER: Uniquely functionalized nanoparticles for hierarchical self-assembly of three-dimensional structures Intellectual Merit:The synthesis of T-structures proposed in this work could serve as an interesting model system for a plasmonic switch. The site-specific modification of particle surfaces, i.e., patch particles, and subsequent molecularly directed assembly advance the area of self-assembly by providing guidelines for the choice of binding energies, particle concentrations, and patch sizes. The T-structure assembly serves as a model system for achieving branched structures containing the elements crucial for three-dimensional assembly. Further, the patchy particles may also serve as surfactants, sensors, and particle probes for the advancement of the understanding of colloidal suspensions and emulsion stabilization. Broader Impact: CCNY is a recognized minority-serving institution, which serves a diverse undergraduate student body of Hispanic (36%), African American (30%), Asian (23%), and White (21%) students. The students will profit from the active research in the area of molecularly directed particle assembly. The organization of an IREU program provides CCNY undergraduates with exposure to research at an international level. Further, the individual mentoring proposed will provide female and minority students with a mentoring network early on in their careers. Collaboration with the Louis-Stokes Alliance for Minority Participation (LSAMP) will channel students from underrepresented groups into the program. The exposure of future journalists, writers, and producers to nanotechnology is likely to have a strong impact on our media-oriented society and will help to increase the awareness of non-technical writers to the potential applications of nanotechnology and the effect of public opinion on the development of the area.
