Researchers at the University of Connecticut were inspired by the skins of squids and jellyfish, which can change color or texture in response to certain factors in their surroundings.
In a move that would make Q from the James Bond series blush, the scientists—who presented their findings at the 52nd National Meeting & Exposition of the American Chemical Society on Sunday, said they’ve replicated the properties of skin in a thin film that can be used to encrypt secret messages or create anti-glare surfaces. When exposed to moisture, its properties can change, thereby revealing things that weren’t there before.
