Butterfly wings offer guiding light for Nanotech Innovation

from TechNewsWorld

The Morpho butterfly's highly evolved wings are so unique that scientists at Simon Fraser University (SFU) 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 — the study of insects — used nanoscale microscopic holes that interact with light to reproduce the butterfly's shimmering signature wherever a counterfeit-proof watermark is desired: In bank notes, legal documents, merchandise, concert tickets, stock certificates, visas, passports, and pharmaceutical products, to name a few of the possible uses. more
