Artificial color-changing material that mimics chameleon skin can detect seafood freshness
E-Mail IMAGE: This image shows the color change of the "chameleon skin " hydrogel-based chemosensor in response to biogenic volatile amine vapors, which are a well known indicator of fish and shrimp spoilage.... view more Credit: Lu et al./Cell Reports Physical Science Scientists in China and Germany have designed an artificial color-changing material that mimics chameleon skin, with luminogens (molecules that make crystals glow) organized into different core and shell hydrogel layers instead of one uniform matrix. The findings, published May 6 in the journal Cell Reports Physic...
