Gorgeous Rainbow-Colored, Stretchy Film that Distinguishes Sugars | Headline Science
Rainbows and sugar may conjure up images of a certain leprechaun-branded breakfast cereal. But now, researchers in ACS Nano report a kaleidoscope-like film for telling different sweeteners apart. The material displayed multiple colors when stretched by hand. But when evenly stretched, it enhanced the unique shifts in fluorescence intensity of 14 sugars, distinguishing between them in beverages and sweat samples.
