We propose to explore the construction of a high resolution scanning probe microscope capable of gathering inelastic electron tunneling spectra (IETS) from biological samples with nm resolution. This would be the first high-resolution instrument for mapping the distribution of organic molecules. It will be based on an atomic force microscope operated at helium temperatures. IETS of a thin-film sample will be gathered using a conductive coating on the tip. Achieving this goal requires major advances in AFM technology, microtome technology and sample mounting methods. Here, We request a Small Grant for Exploratory Research in order to carry out a feasibility study with a much simpler system, an AFM equipped for IETS and operating at liquid nitrogen temperatures.

我们建议探索建设一个高分辨率的扫描探针显微镜能够收集非弹性电子隧道光谱（IETS）从生物样品与纳米分辨率。这将是第一个绘制有机分子分布的高分辨率仪器。它将基于在氦温度下操作的原子力显微镜。将使用尖端上的导电涂层收集薄膜样品的IETS。 实现这一目标需要在原子力显微镜技术，切片机技术和样品安装方法的重大进展。在这里，我们申请一笔探索性研究的小额赠款，以便用一个更简单的系统进行可行性研究，即为IETS配备的AFM，并在液氮温度下运行。
