Workshop on "Chiro-Optical Effects in Nanomaterials"

On November 15th 2019, the workshop on "Chiro-Optical Effects in Nanomaterials" was successfully held in Osaka Prefecture University, Nakamozu campus, which was organized by the Center for Novel Science Initiatives (Dept. of Frontier Photonic Science), National Institutes of Natural Science.

The major purpose of the workshop was to improve the fundamental understanding of chiral nanoscience and encourage the exchange of novel ideas of researches, for the researchers of related fields who were non-expert in chiro-optical aspect of nanomaterials.

In this workshop, the three distinguished scientists in the field of chiral nanomaterials, Prof. Alexander O. Govorov (Ohio University; University of Electronic Science and Technology of China), Prof. Gil Markovich (Tel Aviv University), and Prof. Malcolm Kadodwala (University of Glasgow), were invited and gave comprehensive lectures on the chiro-optical nanomaterials and their related phenomena.

The workshop started with the opening remarks of Prof. Hiromi Okamoto (Institute for Molecular Science).

Prof. Alexander O. Govorov lectured on the theoretical models for describing the chiro-optical phenomena of materials and their implications, which is of importance in understanding and further exploiting plasmon-induced chiro-optical response in the nanoparticles and nanoparticle-biomolecule hybrid systems.

As followed, Prof. Gil Markovich introduced various approaches to achieve the chirality and chiro-optical properties in terms of inorganic nanomaterials. His lecture covered the chirality of inorganic materials that emerged from the atomic-level arrangement to the individual nanostructures, nanoparticle assemblies, and nanoparticle-biomolecule hybrids.

Subsequently, Prof. Malcolm Kadodwala gave a talk on the ultrasensitive chirality detection of the organics and biomolecules, which is one of the central applications of chiral plasmonic nanomaterials. He explained the principles of the chirality detections and presented the forefront methods for detecting biomolecular higher-order structures such as proteins, using chiral metamaterial structures.

Fifty-five researchers and students from universities and national institutes attended the workshop and had vigorous discussions related to the topic, which could be a valuable opportunity to strengthen the basic knowledge and give insights on the chiral-optical materials and related phenomena.

This workshop was supported by Center for Mesoscopic Sciences (Institute for Molecular Science, National Institutes of Natural Sciences), Osaka Prefecture University, and Grant-in-Aid for Scientific Research on Innovative Areas "Nano-Material Manipulation and Structural Order Control with Optical Forces."
