This Major Research Instrumentation (MRI) award supports the development of an open-source, dual-probe atomic force microscope (AFM). The AFM is one of the most versatile tools for nanoscience and nanotechnology with the ability to perform a wide variety of manipulation and measurement tasks. Current state-of-the-art AFMs use one probe, requiring the user to switch between manipulation and measurement modes. The dual-probe AFM will exploit the unique geometry of newly developed probes to place two probe tips head-to-head. Each probe and the substrate will be independently actuated creating unprecedented functionality through simultaneous, localized manipulation and measurement. In manipulation tasks (push, pull, cut, pick, position, orient, assemble, twist, etc), one probe will manipulate while the other probe is imaging. A feedback loop will create high-speed, automated manipulation. In lithography tasks (scratch, dynamic plow, oxidation, dip-pen, etc), a similar arrangement will create precision lithography through real-time process regulation and control. In material characterization tasks, the sample will be mechanically, electrically, magnetically, or thermally excited by one probe and measured by the other creating spatially and temporally resolved material measurements under localized excitation. The open-source architecture of the developed instrument will also serve as a unique experimental platform for advanced control systems research.The instrument to be developed has the potential for broad impact in a wide range of research and research training activities. The Missouri S&T Materials Research Center (MRC) will make the instrument available to external users. In addition to materials-related experimentation, the instrument will also be available for control-systems research. Modular code will be provided on the MRC webpage which can be modified and submitted for remote testing. Missouri S&T and the MRC are committed to long-term maintenance and upkeep of this instrument. The instrument will also be used in a variety of educational activities including undergraduate and graduate courses.

这项主要的研究工具（MRI）奖支持开源，双探针原子力显微镜（AFM）的开发。 AFM是纳米科学和纳米技术最通用的工具之一，能够执行各种操纵和测量任务。 当前的最新AFMS使用一个探针，要求用户在操作和测量模式之间切换。 双探针AFM将利用新开发的探针的独特几何形状，以放置两个探针尖端。 每个探针和底物将通过同时的，局部的操作和测量来独立启动，从而创建前所未有的功能。 在操纵任务（推，拉，切割，挑选，位置，东方，组装，扭曲等）中，一个探针会操纵，而另一个探针正在成像。 反馈循环将产生高速自动操作。 在光刻任务（刮擦，动态犁，氧化，浸入式式等）中，类似的布置将通过实时过程调节和控制来创造精确的光刻。 在材料表征任务中，样品将通过一个探针机械，电气，磁或热激发，并通过另一个探针进行测量，在局部激发下产生空间和时间分辨的材料测量。 开发仪器的开源体系结构还将作为高级控制系统研究的独特实验平台。开发的工具具有在广泛的研究和研究培训活动中产生广泛影响的潜力。 密苏里州S＆T材料研究中心（MRC）将向外部用户提供该仪器。 除了与材料相关的实验外，该仪器还将用于控制系统研究。 MRC网页上将提供模块化代码，可以修改并提交以进行远程测试。 密苏里州S＆T和MRC致力于长期维护和维护该工具。 该乐器还将用于各种教育活动，包括本科和研究生课程。
