Preventing Bank and credit cards Fraud – Butterflies Comes to the Rescue

A study of the stunningly bright and beautiful colors found on the wings of Indonesian Peacock or Swallowtail butterfly (Papilio blumei) might come in handy for the banking industry. It has the potential revolutionize the security printing industry.
 Till now mimicking nature's most colourful, eye-catching surfaces of butterfly wings has proved elusive. The colours are produced by light bouncing off microscopic structures on the insects' wings.
Using a combination of nanofabrication procedures Dr Mathias Kolle, working with Professor Ullrich Steiner and Professor Jeremy Baumberg of the University of Cambridge made structurally identical copies of the butterfly scales, and these copies produced the same vivid colours as the butterflies' wings.
The artificial structures could be used to encrypt information in optical signatures on banknotes and credit cards to protect them against forgery.
Full details appear in the latest issue of journal Nature Nanotechnology.
