摘要

我们开发了一种新的工艺，“3D- ebd(电子束沉积)”，以形成3D线框和纳米尺寸的结构。利用这种方法，我们在玻璃针的尖端形成了一个直径20纳米的纳米探针，并利用它从人类染色体中提取了一根DNA纤维。我们还将其应用于使用SNOM(扫描近场光学显微镜)进行单个DNA观察。

3D nano wire-frame for handling and observing a single DNA fiber

We developed a new process, "3D-EBD (Electron Beam Deposition)" to form 3D wire-frame and nanometer-sized structures. Using this process we formed a 20 nm diameter nano-probe on the tip of a glass needle, and extracted a single DNA fiber from a human chromosome using it. We are also applying it to a single DNA observation using SNOM (Scanning Near-field Optical Microscope).
