Polymer particles mimic opal's iridescence with nano-hole architecture A research team affiliated with UNIST has developed a novel method to synthesize polymer-based particles that mimic the stunning iridescence of opal gemstones. This innovative approach employs nanostructured, porous microparticles composed of linear block copolymers, offering a sustainable and scalable alternative to conventional dyes and pigments.
