| Research Abstract |
We developed nanometer-sized mechanical tweezers for nanoparticle operation using direct atomic observation by in situ high-resolution transmission electron microscopy. We investigated various processing methods to fabricate fine metallic probes for tweezers, i.e., nanometer scale miniaturization methods of metallic needles. For the processing, we used mechanical polishing methods, focused ion beam processing, and contact-separation methods. As result, we obtained nanometer metallic probes. Using the probes, we could produce sandwiched structures of carbon nanocapsules and fullerene molecules. In addition to such nanocraft, we also investigated interaction between nanoprobes and nanoparticles during tweezers operation.
