With this award from the Major Research Instrumentation (MRI) and Chemistry Research Instrumentation and Facilities (CRIF) programs, Purdue University acquires an atomic force microscope (AFM). Scanning probe instrumentation, such as a force microscope, has become central in characterizing materials at submicron scales for applications ranging from photolithographic patterning to studies of biological structure. In the past decade, substantial advances in atomic force microscopy have led to the ability to characterize materials in some cases down to the atomic scale, opening new doors in the understanding of how material structure impacts properties. In addition to its impact on research, the instrument advances the training of students at all levels in this modern technique preparing them for careers in the modern workplace. The proposal is aimed at enhancing research especially in areas such as: (a) robust amphiphilic interfaces for energetic materials and biological structure; (b) self-assembled DNA nanomaterials for scalable nanomanufacturing; (c) functionalized collagen peptide supramolecular assemblies; (d) bioresponsive nanocarriers based on pseudorotaxanes; (e) block copolymers for organic photovoltaics; (f) energy transfer and charge carrier dynamics in solar energy conversion systems; and (g)conjugated materials and polymer composites for flexible printed electronics.

凭借主要研究仪器（MRI）和化学研究仪器和设施（CRIF）计划的这一奖项，普渡大学获得了原子力显微镜（AFM）。扫描探针仪器，如力显微镜，已成为在亚微米尺度上表征材料的核心，其应用范围从生物结构的图案化到研究。在过去的十年中，原子力显微镜的实质性进展已经导致在某些情况下能够将材料表征到原子尺度，为理解材料结构如何影响性能打开了新的大门。除了对研究的影响外，该仪器还促进了各级学生在这一现代技术方面的培训，为他们在现代工作场所的职业生涯做好准备。该提案旨在加强特别是以下领域的研究：（a）高能材料和生物结构的坚固两亲界面;（B）用于可扩展纳米制造的自组装DNA纳米材料;（c）功能化胶原肽超分子组装;（d）基于伪轮烷的生物响应纳米载体;（e）用于有机光致发光的嵌段共聚物;（f）太阳能转换系统中的能量转移和电荷载流子动力学;（g）用于柔性印刷电子的共轭材料和聚合物复合材料。
