报告介绍
报告摘要:
Here we propose a novel methodology “hand-operating nanotechnology” where molecular orientation, organization and even functions in nanometer-scale can be operated by our macroscopic (hand) operation. This concept can be realized at dynamic two-dimensional medium such as thin films at the air-water interface because this medium possess both features of bulk and molecular dimension. For example, we successfully manipulated molecular machines at the air-water interface upon bulk (10-100 cm size) motion of the entire monolayer and realized “capture and release” of aqueous guest molecules using molecular machine, steroid cyclophane (see Figure). In addition, mechanically controlled chiral recognition of amino acid and discrimination of nucleosides by the supramolecular monolayer was successfully demonstrated. The concept has been also applied to indicator-displacement assay for sensor usage.
These examples demonstrate our new concept, manual nanotechnology so-called, hand-operating nanotechnology, with which we can manually control nano/molecular phenomena and functions by macroscopic mechanical force such as hand motions. Using hands for functional operation would be most environmentally friendly and least energy consuming technology.

报告人简介:
  Prof. Katsuhiko ARIGA completed his PhD from Tokyo Institute of Technology in 1990. From 1987 to 1992, he worked as an assistant professor at Tokyo Institute of Technology. And then, he was appointed as a JST Group Leader (Supermolecules Project) and CREST Researcher from 1992 to1998. Then, he joined Nara Institute of Science and Technology as Associate Professor in 1998 and was promoted to principal investigator in 2004 at MANA. Prof. Katsuhiko Ariga has authored and co-authored more than 500 papers (citations 18,000, H index = 72, named as a Highly Cited Researcher by Thomson Reuters (ISI Web of Knowledge)). He served as an Editorial Advisory Board Member of Advanced Materials, Chemistry of Materials, and Langmuir. Prof. Katsuhiko Ariga has been working on supramolecular chemistry especially related with self-assembly processes, ultrathin films and molecular recognitions. Accomplishments in his researches contribute significantly developments of biomemetic systems as well as physicochemical understanding on interfacial phenomena. Especially, pioneer researches of layer-layer supramolecular assembly have been highly evaluated, and he is also recognized as an authority of supramolecular recognition at the interfaces. Total citation of entire researches exceeded 7000 times. Now, his research team is working on frontier researches for supramolecular materials through entire bottom-up process.
