In a new study published by Cell Press, experts are describing a new material that can be used to detect seafood freshness. The hydrogel chemosensor, which mimics chameleon skin, changes color in response certain vapors that are released as fish spoils. According to the researchers, the material may also be used to advance the development of stretchable electronics, dynamic camouflaging robots, and anticounterfeiting technologies. Study co-author Tao Chen is a professor at the Ningbo Institute of Materials Technology and Engineering at the Chinese Academy of Sciences.  "This novel …
