Abstract :
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)
