Bio-Compatible Photonic Crystals

Bio-compatible photonic crystals represent an innovative approach to sustainable color engineering through their unique nanostructures. Our research explores hydroxypropyl cellulose (HPC)-based materials that create vibrant structural colors, offering an eco-friendly alternative to traditional synthetic dyes. These materials demonstrate exceptional potential in both photonic cosmetics and automotive coatings, where their natural coloration mechanism provides enhanced durability and environmental sustainability. The technology enables the development of sustainable pigments that maintain high performance while meeting growing demands for environmentally conscious solutions in the cosmetic and automotive industries.
