Nanoscale Interdisciplinary Research Teams (NIRT)GATED TRANSPORT THROUGH CARBON NANOTUBE MEMBRANES Our interdisciplinary team will use a combination of experimental and simulation tools to conduct a study that would greatly improve our understanding of the nature and control of molecular transport through carbon nanotubes. Our project will explore the following two broad topics:. Fundamentals of molecular interactions with CNTs and the effects of spatial confinement on the molecular structure, dynamics and transport.. Active regulation and control of molecular selectivity and transport through carbon nanotubes using highly specific DNA-based molecular gating.Intellectual MeritThe proposed research will broaden and enhance the fundamental science of nanofluidics. We will not only investigate the effect of confinement that has implications for understanding ionic and water transport in living cells, but also lay the foundation for the development of membrane-based transformational technologies. The newly discovered phenomenon of fast transport through carbon nanotubes will be exploited to enable improvements in the performance of membranes for desalination, gas separation as well as other applications such as protective gear and drug delivery.Broader Impacts Beyond the training of graduate and undergraduate students on nano-bio-fluidics and the strengthening the course curricula at the partner institutions, we will design and implement co-taught graduate level courses. We will also place special emphasis on the recruitment of minority and underrepresented students.The main research and educational theme of this work is: Active Nanostructures.

纳米级跨学科研究团队（NIRT）通过碳纳米管膜的门控传输我们的跨学科团队将使用实验和模拟工具的组合进行研究，这将大大提高我们对通过碳纳米管的分子传输的性质和控制的理解。我们的项目将探讨以下两个广泛的主题：分子与碳纳米管相互作用的基本原理以及空间限制对分子结构，动力学和输运的影响。利用高度特异性的基于DNA的分子门控，通过碳纳米管主动调节和控制分子的选择性和运输。智力价值拟议的研究将拓宽和加强纳米流体的基础科学。我们不仅将研究限制的影响，这对理解活细胞中的离子和水的运输有影响，而且还为基于膜的转化技术的发展奠定了基础。新发现的碳纳米管的快速传输现象将被利用，以提高膜的性能，用于海水淡化，气体分离以及其他应用，如保护装置和药物输送。更广泛的影响除了培训研究生和本科生纳米生物流体学和加强合作机构的课程设置，我们将设计和实施共同教授的研究生课程。我们还将特别重视少数民族和代表性不足的学生的招聘。这项工作的主要研究和教育主题是：有源纳米结构。
