The successful development of nanomachines is pivotal for the realization of future intelligent nanorobots, nanofactories, and nanomedicine. Through applications in nano and micro surgery, targeted drug delivery, and environmental pollutant removal, the impact of nanomachines on every aspect of daily lives as well as the global economy is expected to be significant. However, the manufacturing of nanomachines is challenging due to the difficulty in combining multiple materials or assembling multiple components into a three-dimensional structure to achieve the desired functionalities. Most currently reported nano and micromachines are limited to very simple designs with spherical or cylindrical geometries and thus limited functions, while requiring a large amount of labor, time, and cost for fabrication. This award investigates the scalable and efficient manufacturing of multi-material three-dimensional objects consisting of arbitrarily distributed nano-sized building-blocks. The project studies the advent of multi-functionality by nanoparticle localization through patterning and building 3D objects by solidifying particle-polymer suspensions layer-by-layer. Furthermore, this research advances knowledge of multi-material structure design and development, and paves the way for a new scientific paradigm for the design, fabrication, and application of multi-functional nanomachines. Course modules on additive nanomanufacturing are planned for education in engineering both at the two collaborative universities and at local middle and high schools. Special attention is given to encourage the participation of women, persons with disabilities, and traditionally underrepresented groups. Current manufacturing methods for nanomachines are limited by scalability, efficiency, and material and geometric diversity. To overcome these constraints, this project aims to establish a new additive nanomanufacturing strategy for fabricating 3D multi-material particle-polymer nanocomposites, and to test the hypothesis that the localized nanoparticle distribution can produce multi-functionalities. The research approach -- acoustic field-assisted stereolithography -- utilizes an acoustic field to pattern nanoparticles with macro-to-nano scale resolutions and build a 3D object by solidifying the particle-polymer suspensions layer-by-layer. This research integrates multiple physical phenomena with nanomanufacturing and involves various disciplines of science and engineering including modeling and simulation, process design and development, material and device characterization. This project contributes to advances in additive nanomanufacturing, nanotechnology, and innovations in nanomaterials and nanomachines.

纳米机器的成功开发对于实现未来智能纳米机器人，纳米效应和纳米医学的关键性至关重要。通过在纳米和微观手术，有针对性的药物输送以及清除环境污染物中的应用，纳米机器对日常生活各个方面以及全球经济的影响预计将是重要的。但是，由于难以将多种材料组合或将多个组件组装成三维结构以实现所需功能，因此纳米机器的制造是具有挑战性的。目前，大多数报道的Nano和Micromachines仅限于具有球形或圆柱形几何形状的非常简单的设计，因此功能有限，同时需要大量的劳动，时间和制造成本。该奖项调查了由任意分布的纳米尺寸建筑块组成的多物质三维对象的可扩展性生产。该项目通过固化粒子聚合物悬架逐层固定和构建3D对象来研究纳米颗粒定位的多功能性的出现。此外，这项研究促进了多物质结构设计和开发的知识，并为多功能纳米机器设计，制造和应用的新科学范式铺平了道路。计划在两所合作大学以及当地的中学和高中进行添加纳米制造的课程模块进行工程教育。特别注意鼓励妇女，残疾人和传统代表性不足的群体的参与。纳米机器的当前制造方法受到可扩展性，效率以及材料和几何多样性的限制。为了克服这些约束，该项目旨在建立一种用于制造3D多物质粒子聚合物纳米复合材料的新的添加纳米制造策略，并测试局部纳米颗粒分布可以产生多功能性的假设。研究方法 - 声场辅助立体光刻 - 利用声场用宏观到纳米尺度的分辨率来模拟纳米颗粒，并通过巩固粒子聚合物悬架的一层分层来构建3D对象。这项研究将多种物理现象与纳米制造相结合，涉及科学和工程的各种学科，包括建模和模拟，过程设计和开发，材料和设备表征。该项目有助于纳米材料和纳米机器的添加纳米制造，纳米技术以及创新。
