Nanophotonics—the precise manipulation of light using sub-wavelength structures—is a rapidly advancing field driving global innovation, particularly through high-refractive-index dielectric nanoantennas. Despite its significant scientific and technological potential, Japan currently lacks a clearly established global research hub in this area.

Our group seeks to fill this gap by developing a unique method for the mass production of high-quality crystalline silicon nanoparticles with ideal Mie resonance characteristics. Leveraging an extensive international network, we are establishing a research hub centered at Kobe University that promotes collaboration from fundamental physics to applied biological technologies.

A major achievement of this research is the demonstration of one of the world’s lightest structural color coatings. Our single-layer, Mie-resonance-based silicon ink enables vivid, angle-independent coloration and has the potential to drastically reduce environmental impact through weight reduction.

By fostering high-impact international research and nurturing young researchers through long-term exchanges, this project aims to significantly enhance Kobe University’s global research presence in nanophotonics.
