中文摘要
提案编号:0810294标题:CPA-DA:Hierarchy Design Tools for Bio-NEM主要调查者:N.R.Aluru研究所:伊利诺伊大学香槟分校摘要聚合物因其可响应各种刺激(如pH、盐浓度、电场等)而成为纳米机电(NEMS)的诱人材料。聚合物易于制造、廉价、一次性、生物兼容、低功率致动器,并具有诱人的灵敏度和选择性性能。基于聚合物的NEMS在传感细胞、蛋白质、DNA和生物分子方面得到了应用,并作为微流控网络的关键部件在化学和生物分析中得到了应用。基于聚合物的生物NEMS设备与微流体、MEMS和控制电子学相结合,可以在集成系统的设计和开发方面取得重大进展。这项建议的目标是开发分层设计工具,以实现生物NEMS的快速设计和开发。拟议的研究重点是进行量子力学研究以了解聚合物的静电行为,原子模拟以了解聚合物中的扩散并提取表征生物材料本构行为的应力-应变关系,基于耦合的化学、电气和力学理论的连续介质计算以了解宏观响应,以及从详细和广泛的连续介质模拟中提取生物NEMS器件的紧凑模型。这里提出的研究是多学科的,可以从这项研究中受益的一些应用是纳米级传感和驱动、DNA提纯、化学和生物处理等。该项目将导致在高度交叉的生物NEMS领域培养研究生。从事这个项目的学生将接受有关量子、原子和连续介质模拟方法、聚合物物理、系统级建模和大规模集成生物-NEMS系统设计的培训。该项目的成果将在世界各地的档案期刊和会议上公布。此外,该项目的成果将被纳入UIUC现有的MEMS建模与仿真课程和暑期学校。
英文摘要
Proposal Number: 0810294Title: CPA-DA: Hierarchical Design Tools for Bio-NEMSPrincipal Investigator: N. R. Aluru Institution: University of Illinois at Urbana-ChampaignAbstractPolymers are attractive materials for nanoelectromechanical (NEMS) as they can respond to various stimuli such as pH, salt concentration, electric field, etc. Polymers are easy to manufacture, cheap, disposable, biocompatible, low-power actuators and exhibit attractive sensitivity and selectivity properties. Polymer-based NEMS find applications in sensing cells, proteins, DNA and biomolecules, and as key components in microfluidic networks with applications in chemical and biological analysis. Polymer-based bio-NEMS devices when combined with microfluidics, MEMS, and control electronics can enable significant advances in the design and development of integrated systems. The objective of this proposal is to develop hierarchical design tools to enable rapid design and development of bio-NEMS. The proposed research focuses on performing quantum-mechanical studies to understand the electrostatic behavior of polymers, atomistic simulations to understand diffusion in polymers and to extract stress-strain relations characterizing the constitutive behavior of the biomaterials, continuum calculations based on coupled chemical, electrical, and mechanical theories to understand the macroscopic response, and extracting compact models for bio-NEMS devices from detailed and extensive continuum simulations. The research proposed here is multidisciplinary and some of the applications that could benefit from this research are nanoscale sensing and actuation, DNA purification, chemical and biological processing, etc. This project will result in the education of graduate students in the highly interdisciplinary area of bio-NEMS. Students working on this project will be trained in quantum, atomistic and continuum simulation methods, physics of polymers, system-level modeling and design of large scale integrated bio-NEMS systems. The results from this project will be presented in archival journals and conferences around the world. In addition, the results from this project will be integrated into an existing course on modeling and simulation of MEMS and summer schools offered at UIUC.
