In the upcoming circular economy, advanced management of raw materials, products, and recyclables will be essential. Furthermore, in Society 5.0, the integration of the physical world, where humans live, with the cyber world of digital information will serve as a core technology. Traditionally, stickers and labels have been used for item management. However, risks such as removal, misuse, and reverse engineering through visual inspection have been identified as significant challenges. To address these issues, we have developed a groundbreaking traceability technology. This innovation involves printing or applying our proprietary ultra-small gold nanotags onto products and detecting their unique spectral waveforms as signatures. Gold nanoparticles, which are smaller than the wavelength of light, function as antennas or lenses, concentrating light through the nanoscale optical effects of plasmons. This light-concentration property enables self-assembled gold nanoparticles to exhibit “Surface Enhanced Raman Scattering (SERS),” significantly enhancing the Raman scattering of nearby molecules. We have developed the world’s only technology capable of utilizing SERS while gold nanoparticle self-assemblies remain dispersed in liquid form. By leveraging this technology, we aim to commercialize Raman scattering-enhanced sensing solutions that eliminate the need for dyes, alongside ultra-small gold nanotags designed to enhance supply chain security.
