Acquisition of an Atomic Force Microscope for Research and Research Training at UNC

在主要研究仪器(MRI)计划的支持下，北科罗多大学化学系将获得一台原子力显微镜(AFM)。这台设备将被用来a)研究带有末端官能团的硅烷在云母表面形成初始硅烷单分子层的稳定性，b)探索氧化锌纳米柱的沉积和氧化锌纳米线的掺杂，c)评估蛇毒毒素与特定受体的相互作用，以及d)建立裸子植物木材托轮凹坑膜的三维表示。化学是一门在分子水平上研究结构和过程的科学。在过去，化学家们学会通过执行集体光谱学来检查和阐明分子事件，即测量溶液或固态实验的平均性质。包括原子力显微镜在内的现代技术可以在更小的范围内进行测量。原子力显微镜可以直接观察和理解化学和生物过程中发生的分子事件，使微观结构与宏观性质相关联，并允许设计具有纳米特征的材料。这些研究将在多个领域产生影响，包括材料科学和生物化学。

With support from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at the University of Northern Colordo will acquire an atomic force microscope (AFM). This equipment will be used to a) investigate initial silane monolayer formation stability on mica surfaces using silanes with terminal functional groups, b) explore zinc oxide nanocolumn deposition and doping of zinc oxide nanowires, c) evaluate snake venom toxin interactions with specific receptors, and d) develop a 3-D representation of the torusbearing pit membrane of gymnosperm woods.Chemistry is a scientific discipline that studies structure and processes at the molecular scale. In the past, chemists learned to examine and elucidate molecular events by performing collective spectroscopy, that is, measuring average properties from solution or solid-state experiments. Modern techniques, including AFM, allow measurements at a much smaller scale. AFM allows the direct observation and understanding of molecular events occurring in chemical and biological processes, enables the correlation of microscopic structures to macroscopic properties, and permits the design of materials with nanoscopic features. These studies will have an impact in a number of areas, including materials science and biochemistry.
