Experimental NanofluidicsUnderstanding and controlling fluid flow at the nanoscale is a subject of intense current interest. Recent simulation studies have found unexpected results and this behaviour has recently been confirmed experimentally. In particular, transport of gases and liquids through pores < 2 nm has been measured to occur more than three orders of magnitude more rapidly than predicted by conventional theory. This discovery has significant implications, both for our understanding of how fluids behave at very small length scales and for the design of nanofluidic devices with application in medical diagnosis, medical therapy, sensing and materials separation.The research outlined in this proposal is centred on these emerging phenomena in nanofluidics. The flow of fluids through the central pores of carbon nanotubes and nanopipes will be the primary focus. The emphasis is on a program of basic experimental work aimed at understanding the underlying science, exploring key applications of the associated technology and developing an early stage capability for fabricating and evaluating prototype nanofluidic devices.Five objectives are identified as detailed in the previous section of this application:1) Fabrication of nonporous materials2) Characterisation of fluid flow3) Interaction with nanoparticles4) Exploration of device architectures5) Collaboration with biologistsThis 27 month project will be directed by Prof N Quirke, a pioneer in computational and theoretical nanofluidics. The experimental work will be carried out in the Chemistry Department at Imperial College. An unusual feature of the project team is close collaboration between experimentalists and theoreticians, particularly in using molecular modeling techniques to guide design and provide bidirectional feedback.The funding that is requested in this application primarily covers consumables, small items of equipment and electron microscope time. It will significantly accelerate the rate of progress that can be achieved by an established team and enhance UK science output in an important new field. The project is a collaboration with RGB Research, an SME based in London developing nanomaterials applications.

实验纳米流体学理解和控制纳米尺度的流体流动是当前人们强烈关注的主题。最近的模拟研究发现了意想不到的结果，并且这种行为最近已通过实验得到证实。特别是，气体和液体通过 < 2 nm 的孔隙的传输已被测量为比传统理论预测的速度快三个数量级以上。这一发现对于我们理解流体在非常小的长度尺度上的行为以及在医学诊断、医学治疗、传感和材料分离中应用的纳米流体设备的设计具有重要意义。本提案中概述的研究集中在纳米流体中的这些新兴现象。流体通过碳纳米管和纳米管中心孔的流动将是主要焦点。重点是旨在了解基础科学、探索相关技术的关键应用以及开发制造和评估原型纳米流体设备的早期能力的基础实验工作计划。本申请的前一部分详细说明了五个目标：1) 无孔材料的制造2) 流体流动的表征3) 与纳米颗粒的相互作用4) 设备架构的探索5) 与 这个为期 27 个月的项目将由计算和理论纳米流体学先驱 N Quirke 教授指导。实验工作将在帝国理工学院化学系进行。该项目团队的一个不寻常的特点是实验学家和理论家之间的密切合作，特别是在使用分子建模技术来指导设计和提供双向反馈方面。本申请所需的资金主要涵盖消耗品、小型设备和电子显微镜时间。它将显着加快现有团队取得的进展速度，并提高英国在重要新领域的科学产出。该项目是与 RGB Research 合作的，RGB Research 是一家位于伦敦的中小企业，开发纳米材料应用。
