Gold nanoparticles, which are smaller than the wavelength of light, are surrounded by a type of light called plasmons. This makes the gold nanoparticles act like an antenna or lens that collects and concentrates light. Using this property of concentrating photoelectric fields, we are developing dye-free analytical technology and tiny stealth tags for supply chain security.

We are developing near-future technology that enables anti-counterfeiting, distribution control (traceability), and dose control by applying a special liquid of gold nanoparticles directly to products.

We provide a low-cost and easy-to-use surface-enhanced Raman scattering (SERS) co-aggregation method by controlling the plasmonic nano-aggregation structure of gold nanoparticle self-assembly.
