The Morpho butterfly’s highly evolved wings are so unique that scientists at Simon Fraser University have teamed up with NanoTech Security to reproduce their iridescent blue coloring for a new anti-counterfeiting technology. A clever pairing of nanotechnology and entomology used nanoscale microscopic holes that interact with light to reproduce the butterfly’s shimmering signature wherever a counterfeit-proof watermark is desired: e.g., in bank notes, legal documents, merchandise, concert tickets, stock certificates, visas, passports, and pharmaceutical products.
