  • Metal multi-nanopore structures for quantum dot lasing
    Grants-in-Aid for Scientific Research
    01 Apr. 2019 - 31 Mar. 2022
    Ryuzaki Sou
    A novel laser has been developed by metal multi-nanopore structure with a diameter of ca.100 nm filled with a solution in which quantum dots (QDs) are dispersed. The Fabry-Perot type lasing is caused by plasmonic resonances between the emission from QDs and the metal multi-nanopore structure. In this study, the following results have been mainly achieved. (1) Development of a method to control the emission characteristics of quantum dots after synthesis, (2) Fabrication and characterization of plasmonic nanopores, (3) Revealing the correlation between electronic state at the metal-organic interface and plasmon resonance properties, (4) Fabry-Perot type lasing by the metal multi-nanopore structure.

    Exosomes are extracellular vesicles and play an important role for cancer tumorigenesis, cancer progression, and cancer metastasis. And, exosomes have more information than conventional blood biomarkers. Recently, researchers expected exosomes as the next-generation cancer diagnosis biomarkers. In this research, we proposed a device to demonstrate rapid and precise analysis of cancer specific exosomes using nanospace unique features. And furthermore, we had a goal to aim for cancer diagnosis system, which could achieve higher speed and more accurate diagnosis than conventional systems.

  • Nanopore devices for structural analysis of nanobio materials

    Rapid structural analysis of nanoscale matter in a liquid environment represents innovative technologies that reveal the identities and functions of biologically important molecules. However, there is currently no method with high spatio-temporal resolution that can scan individual particles in solutions to gain structural information. Here we report the development of a nanopore platform realizing quantitative structural analysis for suspended nanomaterials in solutions. We used a low thickness-to-diameter aspect ratio pore architecture for achieving cross sectional areas of analyte (i.e. tomograms). Combining this with multiphysics simulation methods to translate ionic current data into tomograms, we demonstrated rapid structural analysis of many kind of single vesicles and EVs. The present results indicate this structural analysis is very powerful tool to identify nano-bioparticles and have a potential as novel nanobio sensors from the view point of particle shapes.

    This study aimed at multidimensional self-assembly of metallic nanoparticles, and theoretical and experimental elucidation of novel optical phenomena developed in this study, and development of novel nano-optical devices using these phenomena. The main scientific achievement is to reveal the origin of color change observed on multidimensional self-assembled metal nanoparticle sheets on a metal substrate, as "electromagnetically induced transparency (EIT)". The main achievements in application are
    development of colorimetric sensors by use of EIT and super resolution imaging of cell attached nano interface. These our original studies disseminate the fundamental field of plasmonic and nanometamaterials to the world.

  • Nanopore devices for a structural analysis of single molecules

    Nanopore devices consisting of a surround gating electrode causing a decrease in speed of nanomaterials passing through the nanopore have been fabricated in order to analyze structures of the materials. The gating voltage via a gating electrode resulted in 240 times slower speed of nanoparticles passing through a nanopore than that without the gating voltage, and DNA also showed 10 times slower speed under the gating voltage. In addition, the shapes and structures of these materials passing through a nanopore were quantitatively revealed by analysing changes in ionic current due to the material translation.
